    1. The COVID-19 syndemic, with a disproportionately higher adverse impact on communities of color (i.e., COVID-19 infection and death), will likely exacerbate the existing health disparities in trauma-related symptoms between people of color (POC) and White Americans. However, no studies have examined the racial disparities in posttraumatic stress symptoms (PTSS) during COVID-19. Grounded in ecological theory and racial trauma framework, we investigated rates of racial disparities in PTSS and three possible mechanisms, 1) COVID stress, 2) direct racism, and 3) indirect racism, for these discrepancies using a large U.S. national sample (N = 2,019). Results indicated that POC reported higher levels of PTSS than White Americans (d =.21). The PTSS racial disparity was accounted more by direct and indirect racism than by the COVID-19-specific stressors, after controlling for age, gender, education, income, parent status, adverse childhood experiences (ACEs), and intimate partner violence (IPV). Additional fine-grained analyses for Hispanic/Latinx Americans (n = 283), Black/African Americans (n = 279), and Asian American and Pacific Islanders (n = 123) by and large corroborated the above findings. Our findings highlighted the deleterious impact of the ongoing racism pandemic on the POC community as a public health crisis in addition to the COVID-19 pandemic.
    1. Background: The COVID-19 pandemic is a novel population-level stressor. As such, it is important to examine pandemic-related changes in mental health and to identify which individuals are at greatest risk of worsening symptoms. Methods: Online questionnaires were administered to 34,465 individuals in the UK, recruited from existing cohorts or via social media. Around one third (n = 12,718) with prior diagnoses of depression or anxiety completed pre-pandemic mental health assessments, allowing prospective investigation of symptom change. We examined changes in depression, anxiety and PTSD symptoms using prospective, retrospective and global ratings of change assessments. We also examined the effect of key risk factors on changes in symptoms. Outcomes: Prospective analyses showed small decreases in depression (PHQ-9: - .43 points) and anxiety symptoms (GAD-7: -.33 points), and increases in PTSD symptoms (PCL-6: .22 points). Conversely, retrospective analyses demonstrated large significant increases in depression (2.40 points) and anxiety symptoms (1.97 points) and 55% reported worsening mental health since the beginning of the pandemic on a global change rating. Using both prospective and retrospective symptom measures, regression analyses demonstrated that worsening depression, anxiety and PTSD symptoms were associated with i) prior mental health diagnoses, ii) female gender; iii) young age, and iv) unemployed or student status. Interpretation: We highlight the effect of prior mental health diagnoses on worsening mental health during the pandemic and confirm previously-reported sociodemographic risk factors. Discrepancies between prospective and retrospective measures of changes in mental health may be related to recall bias underestimating prior symptom severity.
    1. The COVID-19 pandemic is increasing older people's existing challenges in engaging with their physical and social worlds, and is thereby likely to worsen their loneliness. Digital technology has been offered as a potential aid for social connectedness during social distancing/isolation. However, many popular digital communication tools have not been designed to specifically address the needs of older adults impacted by social isolation. We propose that the social identity approach to health and the Social Identity Model of Identity Change (SIMIC) could be a foundation for digital interventions to address loneliness. While SIMIC applies to maintaining wellbeing during life transitions, it has not previously been rigorously applied to digital interventions. There are known challenges to integrating psychological theory to the design of digital technology, such as efficacy, user-autonomy, and engagement. The interdisciplinary field of Human Computer Interaction has a history of drawing on models originating from psychology to improve the design of digital technology and to design technologies in an appropriate manner. Drawing on key lessons from this literature, we consolidate design guidelines that could assist in applying SIMIC to digital interventions for loneliness in older people affected by the pandemic.
    1. While scholarly attention to date has focused almost entirely on individual-level drivers of vaccine confidence, we show that macro-level factors play an important role in understanding individual propensity to be confident about vaccination. We analyse data from the 2018 Wellcome Global Monitor survey covering over 120,000 respondents in 126 countries to assess how societal-level trust in science is related to vaccine confidence. In countries with a high aggregate level of trust in science, people are more likely to be confident about vaccination, over and above their individual-level scientific trust. Additionally, we show that societal consensus around trust in science moderates these individual-level and country-level relationships. In countries with a high level of consensus regarding the trustworthiness of science and scientists, the positive correlation between trust in science and vaccine confidence is stronger than it is in comparable countries where the level of social consensus is weaker.
    1. We study the changes in greeting behavior caused by the COVID-19 pandemic. We find that after the use of handshakes and social kissing as forms of greeting decreased drastically, they became common again already a few months after the outbreak. Nevertheless, a consistently large proportion of respondents (around 57%) plan to change their greeting behavior permanently, either because they simply became used to it or because they want to avoid the danger of contracting and transmitting infectious diseases. As can be seen from the results of the first survey wave in April, 2020, the belief in conspiracy theories about COVID-19 did not influence the greeting behavior of individuals, but it proved to have a strong impact in the second survey wave in September, 2020.
    1. COVID-19 pandemic gave rise to numerous new conspiracy theories related to the virus. The aim of this study was to simultaneously investigate a range of individual predictors of beliefs in COVID-19 conspiracy theories that account for socio-demographic characteristics (age, gender, education, economic standard, the importance of religion and political self-identification), distinctive motivational orientations (social dominance and authoritarianism), relevant social attitudes (sense of political powerlessness and trust in science and scientists) and perceived personal risk (perceived risk for self and family members, concern of being infected and expected influence of pandemic on one’s own economic standard). Participants were 1060 adults recruited from the general public of Croatia. The sample was a probabilistic quota sample with gender, age, level of education, size of a place of living and region of the country as predetermined quotas. The regression model explained 42.2% of the individual differences in beliefs in COVID-19 conspiracy theories. Trust in science and scientists and political powerlessness were the strongest predictors, whereas fear of being infected had the weakest contribution in explaining variance of the criterion. Additionally, results revealed that the relation of authoritarianism with the belief in COVID-19 conspiracies was mediated by trust in science and scientists. The relation between social dominance and belief in conspiracies was also partially mediated by trust in science. Our results suggest that (re)building trust in science and lowering the sense of political helplessness might help in fighting potentially harmful false beliefs about the pandemic.
    1. The complexity of COVID-19 and variation in control measures and containment efforts of different countries have caused difficulties in the prediction and modelling of the COVID-19 pandemic. We attempted to predict the scale of the latter half of the pandemic based on real data using the ratio between the early and latter halves from countries where the pandemic is largely over. We collected daily pandemic data from China, South Korea and Switzerland and subtracted ratio of pandemic days before and after the disease apex day of COVID-19. We obtained the ratio of pandemic data and created multiple regression models for the relationship between before and after the apex day. We then tested our models using data from the first wave of the disease from 14 countries in Europe and the US. We then tested the models using data of these countries from entire pandemics up to March 30, 2021. Results indicates that the actual number of cases of these countries during the first wave mostly fall in the predicted ranges of liner regression excepting Spain and Russia. Similarly, the actual death of these countries mostly falls into the range of predicted data. Using the accumulated data up to the day of apex and total accumulated data up to March 30, 2021, the data of case numbers in these countries are falling into the range of predicted data, except for data from Brazil. The actual number of deaths in all the countries are at or below the predicted data. In conclusion, liner regression model built with real data from countries or regions of early pandemics can predict pandemic scales of the countries which the pandemics occur late. Such a prediction with high degree of accuracy provides valuable information for governments and public.
    1. Background: In response to the COVID-19 pandemic, physical distancing measures have been implemented globally. Canadians have been instructed to stay at home, which has likely resulted in significant changes in their physical activity. Using data from a national physical activity tracking app (PAC app), we aimed to determine device-measured physical activity levels immediately prior to and following the implementation of physical distancing measures in Canada to provide evidence for the development of physical activity recommendations for future pandemics or second wave infections. Methods: Demographic and physical activity data were extracted from the ParticipACTION app (PAC app), using a 10-week (10 February to 19 April 2020) quasi-experimental design to determine changes in physical activity 4 weeks pre-pandemic and 6 weeks post-pandemic declaration. Weekly physical activity levels were monitored through wearable fitness trackers and health apps linked to the PAC app, to record moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and steps. Repeated measure ANOVA was used to determine changes over time (mean ± SE). Findings: A total of 2,338 Canadians who were mostly 35–44 years old (26.6%) and female (90.2%) were included in the analysis. MVPA, LPA, and steps significantly declined immediately following the declaration of the pandemic (MVPA: pre-pandemic: 194.2 ± 5.2 min, post-pandemic: 176.7 ± 5.0 min, p < 0.001; LPA: pre-pandemic: 1,000.5 ± 17.0 min, post-pandemic: 874.1 ± 15.6 min, p < 0.001; steps: pre-pandemic: 48,625 ± 745 steps, post-pandemic: 43,395 ± 705 steps, p < 0.001). However, 6 weeks following pandemic declaration, MVPA (week 6: 204.4 ± 5.4 min, p = 0.498) had returned to pre-pandemic levels. LPA (week 6: 732.0 ± 14.3 min, p = < 0.001) and steps (week 6: 41,946 ± 763, p < 0.001) remained significantly lower than pre-pandemic levels at week 6. Interpretation: Although MVPA returned to pre-pandemic levels, significant and sustained declines in incidental LPA and steps were observed. Attenuating the loss of incidental physical activity should be a public health priority in response to future pandemics or a second wave of a COVID-19 infection, as it may have significant long-term implications for the physical and mental health of Canadians.
    1. In recent years behavioural science has quickly become embedded in national level governance. As the contributions of behavioural science to the UK’s COVID-19 response policies in early 2020 became apparent, a debate emerged in the British media about its involvement. This served as a unique opportunity to capture public discourse and representation of behavioural science in this fast-track, high-stake context. Aimed at identifying elements which foster and detract from trust and credibility in emergent scientific contributions to policy making, in Study 1 we use corpus linguistics and network analysis to map the narrative around the key behavioural science actors and concepts which were discussed in the 647 news articles extracted from the 15 most read British newspapers over the 12-week period surrounding the first hard UK lockdown of 2020. We report and discuss 1) the salience of key concepts and actors as the debate unfolded, 2) quantified changes in the polarity of the sentiment expressed toward them and their policy application contexts, and 3) patterns of co-occurrence via network analyses. To establish public discourse surrounding identified themes, in Study 2 we investigate how salience and sentiment of key themes and relations to policy on original Twitter chatter (N = 2,187). In Study 3, we complement these findings with a qualitative analysis of the subset of news articles which contained the most extreme sentiments (N = 111), providing an in-depth perspective of sentiments and discourse developed around keywords, as either promoting or undermining their credibility in, and trust toward behaviourally informed policy. We discuss our findings in light of the integration of behavioural science in national policy making under emergency constraints.
    1. As covid-19 vaccines begin to arrive in the Andean highlands in Colombia, Maria Pito, a leader of the Nasa people, is reluctant to receive one. “As a nurse, I will be required by the clinic where I work to be vaccinated but if I had the choice, I would not take it and would continue to rely on traditional medicine,” she says. “I and many others don’t trust this untransparent government.”
    1. Vaccine confidence will be the casualty of Europe’s war of words over the AstraZeneca–Oxford vaccine.
    1. Avoid unwarranted certainty, neat narratives and partisan presentation; strive to inform, not persuade.
    1. Background: COVID-19 continues to ravage the world with economies and life significantly and negatively affected. Fortunately, there has been significant progress in the production of vaccines to stem the infection. However, with controversies and myths surrounding vaccinations, it is timely to examine individuals’ willingness to vaccinate. The present study developed and validated the Motors of COVID-19 Vaccination Acceptance Scale (MoVac-COVID19S) and assessed the acceptance of COVID-19 vaccination utilizing the cognitive model of empowerment (CME). Methods: A total of 3145 university students (mean age=20.80 years; SD=2.09) were recruited for the present study between January 5 and 16, 2021. Two MoVac-COVID19S scales (9-item and 12-item) were adapted from the MoVac-Flu Scale, an instrument developed using CME. Psychometric tests were conducted to ascertain reliability and validity properties. Results: The findings indicated that the MoVac-COVID19S had high internal consistency in both the 9-item version (ω=0.921) and 12-item version (ω=0.898). The factor structure of the MoVac-COVID19S (9-item and 12-item versions) corresponded well with CME theory. All the fit indices were satisfactory (CFI=0.984, TLI=0.971, RMSEA=0.088, SRMR=0.058) but the 9-item MoVac-COVID had better fit indices than the 12-item MoVac-COVID due to the negative wording effects existing in the 12-item MoVac-COVID19S. The scale had satisfactory known-group validity in both 9-item and 12-item versions. Conclusions: The MoVac-COVID19S has promising psychometric properties based on internal consistency, factor structure, and known-group validity.
    1. Introduction: Vaccines against COVID-19 have been developed in unprecedented time. However, the effectiveness of any vaccine is dictated by the proportion of the population willing to be vaccinated. In this observational population-based study we examined intentions to be vaccinated against COVID-19 throughout the pandemic. Methods: In November, 2020 we analyzed longitudinal data from a nationally representative sample of 7,547 US adults enrolled in the Understanding America Study (UAS) using multinomial logistic regresion. Participants reporting being willing, undecided and unwilling to get vaccinated against coronavirus across 13 assessments conducted from April-October, 2020. Public attitudes to vaccination against the coronavirus were also assessed on a four-point Likert scale. Results: Willingness to vaccinate declined from 71% in April to 53.6% in October. This was explained by an increase in the percentage of participants undecided about vaccinating (from 10.5% to 14.4%) and the portion of the sample unwilling to vaccinate (from 18.5% to 32%). The population subgroups most likely to be undecided/unwilling to vaccinate were those without a degree (undecided: RRR=2.47, 95% CI: 2.04-3.00; unwilling: RRR=1.92, 95% CI:1.67-2.20), Black participants (undecided: RRR=2.18, 95% CI: 1.73-2.74; unwilling: RRR=1.98, 95% CI:1.63-2.42), and females (undecided: RRR=1.41, 95% CI:1.20-1.65; unwilling: RRR=1.29, 95% CI:1.14-1.46). Participants who were older or were on higher incomes were least likely to be undecided or unwilling to vaccinate. Concerns about potential side effects of a vaccine were common. Conclusions: Intentions to be vaccinated against coronavirus have declined rapidly during the pandemic and close to half of Americans are undecided or unwilling to be vaccinated.
    1. Socioeconomic disparities in mental health have been reported during the COVID-19 pandemic. However, few studies have examined the mechanisms through which such disparities in mental health occurred. This pre-registered study aimed to examine socioeconomic disparities, as indexed by education levels, in the trajectory of mental health at the early stages of the COVID-19 pandemic and whether financial stress associated with the pandemic mediated socioeconomic disparities in mental health. Data were drawn from the Love in the Time of COVID project, of which we included four waves of data (N = 2,204) collected between March 27th and June 21st, 2020. Education was assessed at baseline, and mental health outcomes (i.e., eudaimonic well-being, positive affect, negative affect, depressive and anxious symptoms) and financial stress associated with the COVID-19 pandemic were assessed at each wave. Results indicated that there were educational disparities in eudaimonic well-being, negative affect, and depressive and anxiety symptoms at baseline, with those with lower education levels reporting poorer mental health. However, education did not amplify disparities in mental health outcomes over time, showing no associations with the rates of change in mental health outcomes. Financial stress mediated the associations between education and eudaimonic well-being, negative affect, and depressive and anxious symptoms at baseline, and there were no temporal variations in the mediation effects of financial stress. These results highlight persistent educational disparities in mental health at the early stages of the COVID-19 pandemic, and such educational disparities may be partially explained by financial stress associated with the COVID-19 pandemic.
    1. It took just four months to reach this global milestone, and hitting to the two-billion mark could happen even faster, say scientists.
    1. THE coronavirus pandemic has left children vulnerable to other infections, in part due to reduced interactions as a result of lockdowns and social distancing.
    1. THE covid-19 situation in India is terrible and is likely to get worse. The country has set one new record after another for the most daily coronavirus cases reported in any country. Just as the world was hoping the worst of the pandemic was over, we are seeing its biggest outbreak.
    1. The world has reached the milestone of administering one billion doses of COVID-19 vaccines, just four months after the World Health Organization (WHO) approved the first vaccine for emergency use, and roll-outs began in countries such as the United States and the United Kingdom. The speed at which they have been administered is remarkable, but unequal distribution of the vaccinations highlights global disparities, say researchers (see ‘Divided by doses’).
    1. What motivates human behaviour in social dilemmas? The results of public goods games are commonly interpreted as showing that humans are altruistically motivated to benefit others. However, there is a competing ‘confused learners’ hypothesis: that individuals start the game either uncertain or mistaken (confused) and then learn from experience how to improve their payoff (payoff-based learning). Here we (1) show that these competing hypotheses can be differentiated by how they predict contributions should decline over time; and (2) use metadata from 237 published public goods games to test between these competing hypotheses. We found, as predicted by the confused learners hypothesis, that contributions declined faster when individuals had more influence over their own payoffs. This predicted relationship arises because more influence leads to a greater correlation between contributions and payoffs, facilitating learning. Our results suggest that humans, in general, are not altruistically motivated to benefit others but instead learn to help themselves.
    1. The authors conducted a close replication of a study by Georgiou et al (2020), who found amongst 660 (reported in abstract) or 640 (reported in participant section) participants that 1) Covid-19 related conspiracy theory beliefs were strongly related to broader conspiracy theory beliefs, that 2) Covid-19 related conspiracy beliefs were higher in those with lower levels of education, and that 3) Covid-19 related conspiracy beliefs were positively (although weakly) correlated with more negative attitudes towards different individual items measuring the government’s response. Finally, they find that 4) Covid-19 beliefs were unrelated to self-reported stress. In a pre-registered replication and extension in a study sufficiently well-powered to detect f2 = 0.05, at an alpha level of .05, with an a priori power of .95, and with 5 Predictors in a multiple regression analysis, we do not find the same results. First, we find that education level is unrelated to Covid-19 related conspiracy beliefs, that stress is related to Covid-19 related conspiracy beliefs, but that the government’s response is indeed related to Covid-19 related conspiracy beliefs. We point out measurement problems in measuring conspiracy beliefs, extend the study through supervised machine learning by finding that attachment avoidance and anxiety are important predictors of conspiracy beliefs (Covid-19-related and beyond). Part of the differences between their and our study are likely due to differences in analysis approach; others may be due to the errors in Georgiou et al.’s (2020 reporting.
    1. We test the hypothesis that COVID-19 vaccine hesitancy is attributable to ‘distrustful complacency’ – an interactive and not just additive combination of concern and distrust. Across two studies, 9695 respondents across 13 different parts of Britain reported their level of concern about COVID-19, trust in the UK government, and intention to accept or refuse the vaccine. Multilevel regression analysis, controlling for geographic area and relevant demographics, confirmed the predicted interactive effect of concern and trust. Respondents with both low trust and low concern were 10%-22% more vaccine hesitant than respondents with either high trust or high concern, and 20%-29% more hesitant than respondents with both high trust and high concern. Results hold equally among White, Black, and Muslim respondents, consistent with the view that, regardless of mean level differences, a common process underlies vaccine hesitancy, underlining the importance of tackling distrustful complacency both generally and specifically amongst unvaccinated individuals and populations.
    1. Adherence to government COVID-19-related instructions is important in preventing, detecting, treating and emerging successfully from the acute phase of the pandemic. Public adherence to instructions has been high but will only remain so as long as people’s capabilities, opportunities and motivations are supported. Policy makers should ensure that strategies are developed that will prevent people’s capabilities, opportunities and motivations from being undermined. Men, younger people, and people with black, Asian and minority ethnic backgrounds represent important targets for such interventions.
    1. Worldwide, higher education institutions made quick and often unprepared shifts from on-site to online examination in 2020 due to the COVID-19 health crisis. This development sparked an ongoing debate on whether this development made it easier for students to cheat. We investigated whether students indeed cheated more often in online than in on-site exams and whether the use of online exams was also associated with higher rates of other behaviors deemed as academic dishonesty. To answer our research questions, we questioned 1,608 German students from a wide variety of higher education institutions about their behavior during the summer semester of 2020. The participating students reported that they cheated more frequently in online than in on-site exams. Effects on other measures of academic dishonesty were more negligible. These results speak for the notion that the swift application of ad-hoc online testing during 2020 has led to negative consequences for academic integrity.
    1. Facial emotion recognition is crucial for social interaction. However, in times of a global pandemic, where wearing a face mask covering mouth and nose is widely encouraged to prevent the spread of disease, successful emotion recognition may be challenging. In Study 1, we investigated whether emotion recognition, assessed by a validated emotion recognition task, is impaired for faces wearing a mask compared to uncovered faces, in a sample of 790 participants between 18 and 89 years. Additionally, perception of threat for faces with and without mask was assessed. We found impaired emotion recognition for faces wearing a mask compared to faces without mask, especially for those depicting anger, sadness and disgust. Further, we observed that perception of threat was altered for faces wearing a mask. In Study 2, we compared emotion recognition performance for faces with and without face mask to faces that are occluded by something other than a mask, i.e. a bubble as well as only showing the upper part of the faces. We found that, for most emotions and especially for disgust, there seems to be an effect that can be ascribed to the face mask specifically, both for emotion recognition performance and perception of threat. Methodological constraints as well as the importance of wearing a mask despite temporarily compromised social interaction are discussed.
    1. India’s huge wave of Covid-19 infections has hit the international shipping industry, which relies on the country for seafarers, as crews come down with the disease and ports deny entry to vessels.Ports including Singapore and Fujairah in the United Arab Emirates have barred ships from changing crew members who have recently travelled from India, notices from maritime authorities show. Zhoushan in China has banned the entry of ships or crew that have visited India or Bangladesh in the past three months, according to Wilhelmsen Ship Management, a crew provider.Industry executives also said that crews coming from India were testing positive for Covid-19 on ships, despite quarantining and testing negative before boarding.
    1. We study how publicity in the science press, in the form of highlighting, affects the citations of research papers. Using multiple linear regression, we quantify the citation advantage associated with several highlighting platforms for papers published in Physical Review Letters (PRL) from 2008-2018. We thus find that the strongest predictor of citation accrual is a Viewpoint in Physics magazine, followed by a Research Highlight in Nature, an Editors' Suggestion in PRL, and a Research Highlight in Nature Physics. A similar hierarchical pattern is found when we search for extreme, not average, citation accrual, in the form a paper being listed among the top-1% cited papers in physics by Clarivate Analytics. The citation advantage of each highlighting platform is stratified according to the degree of vetting for importance that the manuscript received during peer review. This implies that we can view highlighting platforms as predictors of citation accrual, with varying degrees of strength that mirror each platform's vetting level.
    1. The story of COVID-19 vaccines and vaccination in Africa is slowly unfolding, as more and more countries across the continent receive shipments of the long-awaited vaccines.
    1. Facebook announced a community review program in December 2019 and Twitter launched a community-based platform to address misinformation, called Birdwatch, in January 2021. We provide an overview of the potential affordances of such community based approaches to content moderation based on past research. While our analysis generally supports a community-based approach to content moderation, it also warns against potential pitfalls, particularly when the implementation of the new infrastructures does not promote diversity. We call for more multidisciplinary research utilizing methods from complex systems studies, behavioural sociology, and computational social science to advance the research on crowd-based content moderation.
    1. Few states collect sexual orientation or gender identity data, so no one knows how many people in some communities are getting vaccinated.
    1. GENEVA -- The World Health Organization urged rich countries on Friday to reconsider plans to vaccinate children and instead donate COVID-19 shots to the COVAX scheme that shares them with poorer nations.
    1. Jerome Kim, director of the International Vaccine Institute in South Korea, told DW that successfully producing and distributing complex vaccines in developing countries will take more than access to biotech secrets.
    1. Epidemiological models have been a source of continual controversy from the start of the pandemic, often blamed for fearmongering and inaccuracy. How well have they done?
    1. The KFF COVID-19 Vaccine Monitor is an ongoing research project tracking the public’s attitudes and experiences with COVID-19 vaccinations. Using a combination of surveys and qualitative research, this project tracks the dynamic nature of public opinion as vaccine development and distribution unfold, including vaccine confidence and acceptance, information needs, trusted messengers and messages, as well as the public’s experiences with vaccination.
    1. The Vaccine Confidence Project, an interdisciplinary and international research group at the London School of Hygiene & Tropical Medicine specialising in monitoring public confidence in vaccines, providing insights and informing strategies to address emerging risks, today announced that they would be joining The Trinity Challenge as its newest member.
    1. In some of these countries where geography imbued its people with a false sense of security and insulation, lawmakers tried to close their countries from the dangerous world that lay beyond their literal shores. Iceland, Australia, and New Zealand have all been the lockdown media’s darlings, as if what these countries experienced – comparatively low infections and deaths – stemmed from wise policy choices that were equally available to the world’s transportation hubs (London, New York) or highly connected countries with next to no ability to restrict movement across borders (U.K., European Union member states or the states of the United States). 
    1. A new variant stealthily took hold on two continents, highlighting the need for global genomic surveillance.
    1. The number of people infected with the coronavirus in England has fallen by half since the end of March. These findings from the Imperial College London-led REACT study are based on over 127,000 home swab tests taken between 15th April and 3rd May. The results show that 0.1% of the population is currently infected, or 1 in 1,000. This compares with the study’s previous testing round when 0.2% or 1 in 500 had the virus as of 30th March.
    1. A new study led by Public Health England and NHS Test and Trace will help increase understanding of how effective daily contact testing could be for people who are contacts of positive COVID-19 cases. It is to be used as an alternative to self-isolation.
    1. Determining policies to end the SARS-CoV-2 pandemic will require an understanding of the efficacy and effectiveness (hereafter, efficacy) of vaccines. Beyond the efficacy against severe disease and symptomatic and asymptomatic infection, understanding vaccine efficacy against transmission will help model epidemic trajectory and determine appropriate control measures. Recent studies have proposed using random virologic testing in individual randomized controlled trials to improve estimation of vaccine efficacy against infection. We propose to further use the viral load measures from these tests to estimate efficacy against transmission. This estimation requires a model of the relationship between viral load and transmissibility and assumptions about the vaccine effect on transmission and the progress of the epidemic. We describe these key assumptions, potential violations of them, and solutions that can be implemented to mitigate these violations. Assessing these assumptions and implementing this random sampling, with viral load measures, will enable better estimation of the crucial measure of vaccine efficacy against transmission.
    1. Early on in the pandemic Germany committed to purchasing all vaccines through the EU despite delays. Now some want to make an exception for the Russian vaccine Sputnik V.
    1. Carlson knows anti-vaxxers have become a big part of Trump’s Republican Party and that they are easy marks as he hustles to up the ante and amp up the outrage.
    1. This document outlines how the national and NHS England region estimates of the reproduction number (R) and growth rate are produced and subsequently published on GOV.UK: section 1 below outlines how each academic group produces their individual estimates, using a mixture of data sources and modelling techniques section 2 below outlines how these estimates are statistically combined to form a single consensus range section 3 below outlines the approval and quality assurance process that the individual and combined estimates go through to ensure they are robust and reliable section 4 below outlines how the final consensus range is communicated
    1. Political polarization appears to be on the rise, as measured by voting behavior, general affect towards opposing partisans and their parties, and contents posted and consumed online. Research over the years has focused on the role of the Web as a driver of polarization. In order to further our understanding of the factors behind online polarization, in the present work we collect and analyze Web browsing histories of tens of thousands of users alongside careful measurements of the time spent browsing various news sources. We show that online news consumption follows a polarized pattern, where users' visits to news sources aligned with their own political leaning are substantially longer than their visits to other news sources. Next, we show that such preferences hold at the individual as well as the population level, as evidenced by the emergence of clear partisan communities of news domains from aggregated browsing patterns. Finally, we tackle the important question of the role of user choices in polarization. Are users simply following the links proffered by their Web environment, or do they exacerbate partisan polarization by intentionally pursuing like-minded news sources? To answer this question, we compare browsing patterns with the underlying hyperlink structure spanned by the considered news domains, finding strong evidence of polarization in partisan browsing habits beyond that which can be explained by the hyperlink structure of the Web.
    1. Background: Despite the proven effectiveness of vaccinations, vaccination uptake is limited in Nigeria. According to the Multiple Indicator Cluster Survey (MICS), one of the main barriers is the lack of accurate knowledge of the vaccination schedule. This study evaluates caregivers’ knowledge of the vaccination schedule and their ability to read the immunization card.Methods: The study evaluated the knowledge of caregivers in 11 settlements in the Jada local government area of Adamawa State in September 2019. The change in knowledge among caregivers before and after referring to the immunization card was evaluated using a simple statistical hypothesis testing (chi-square test). We also used logistic regression analysis to evaluate the determinants of vaccination knowledge, as well as the correlation between knowledge and actual vaccination behaviors.Results: More than half of the women had correct knowledge of the vaccination schedule for critical vaccines. However, the knowledge of the caregivers did not improve after referring to the immunization card which contained the information. Caregivers who brought their children to the clinic for vaccination recently were more likely to know the vaccination schedule correctly. Accurate knowledge was highly correlated with the actual vaccination behaviors.Conclusion: Reference to the immunization card did not improve the knowledge of vaccination schedule, especially among the less-educated population. To increase the demand for vaccinations, one potential policy is to target the uneducated population and help them increase their knowledge.
    1. BackgroundEarly childhood vaccination is an essential global public health practice that saves two to three million lives each year, but many children do not receive all the recommended vaccines. To achieve and maintain appropriate coverage rates, vaccination programmes rely on people having sufficient awareness and acceptance of vaccines.Face‐to‐face information or educational interventions are widely used to help parents understand why vaccines are important; explain where, how and when to access services; and address hesitancy and concerns about vaccine safety or efficacy. Such interventions are interactive, and can be adapted to target particular populations or identified barriers.This is an update of a review originally published in 2013.ObjectivesTo assess the effects of face‐to‐face interventions for informing or educating parents about early childhood vaccination on vaccination status and parental knowledge, attitudes and intention to vaccinate.Search methodsWe searched the CENTRAL, MEDLINE, Embase, five other databases, and two trial registries (July and August 2017). We screened reference lists of relevant articles, and contacted authors of included studies and experts in the field. We had no language or date restrictions.Selection criteriaWe included randomised controlled trials (RCTs) and cluster‐RCTs evaluating the effects of face‐to‐face interventions delivered to parents or expectant parents to inform or educate them about early childhood vaccination, compared with control or with another face‐to‐face intervention. The World Health Organization recommends that children receive all early childhood vaccines, with the exception of human papillomavirus vaccine (HPV), which is delivered to adolescents.Data collection and analysisWe used standard methodological procedures expected by Cochrane. Two authors independently reviewed all search results, extracted data and assessed the risk of bias of included studies.Main resultsIn this update, we found four new studies, for a total of ten studies. We included seven RCTs and three cluster‐RCTs involving a total of 4527 participants, although we were unable to pool the data from one cluster‐RCT. Three of the ten studies were conducted in low‐ or middle‐ income countries.All included studies compared face‐to‐face interventions with control. Most studies evaluated the effectiveness of a single intervention session delivered to individual parents. The interventions were an even mix of short (ten minutes or less) and longer sessions (15 minutes to several hours).Overall, elements of the study designs put them at moderate to high risk of bias. All studies but one were at low risk of bias for sequence generation (i.e. used a random number sequence). For allocation concealment (i.e. the person randomising participants was unaware of the study group to which participant would be allocated), three were at high risk and one was judged at unclear risk of bias. Due to the educational nature of the intervention, blinding of participants and personnel was not possible in any studies. The risk of bias due to blinding of outcome assessors was judged as low for four studies. Most studies were at unclear risk of bias for incomplete outcome data and selective reporting. Other potential sources of bias included failure to account for clustering in a cluster‐RCT and significant unexplained baseline differences between groups. One cluster‐RCT was at high risk for selective recruitment of participants.We judged the certainty of the evidence to be low for the outcomes of children's vaccination status, parents' attitudes or beliefs, intention to vaccinate, adverse effects (e.g. anxiety), and immunisation cost, and moderate for parents' knowledge or understanding. All studies had limitations in design. We downgraded the certainty of the evidence where we judged that studies had problems with randomisation or allocation concealment, or when outcomes were self‐reported by participants who knew whether they'd received the intervention or not. We also downgraded the certainty for inconsistency (vaccination status), imprecision (intention to vaccinate and adverse effects), and indirectness (attitudes or beliefs, and cost).Low‐certainty evidence from seven studies (3004 participants) suggested that face‐to‐face interventions to inform or educate parents may improve vaccination status (risk ratio (RR) 1.20, 95% confidence interval (CI) 1.04 to 1.37). Moderate‐certainty evidence from four studies (657 participants) found that face‐to‐face interventions probably slightly improved parent knowledge (standardised mean difference (SMD) 0.19, 95% CI 0.00 to 0.38), and low‐certainty evidence from two studies (179 participants) suggested they may slightly improve intention to vaccinate (SMD 0.55, 95% CI 0.24 to 0.85). Low‐certainty evidence found the interventions may lead to little or no change in parent attitudes or beliefs about vaccination (SMD 0.03, 95% CI ‐0.20 to 0.27; three studies, 292 participants), or in parents’ anxiety (mean difference (MD) ‐1.93, 95% CI ‐7.27 to 3.41; one study, 90 participants). Only one study (365 participants) measured the intervention cost of a case management strategy, reporting that the estimated additional cost per fully immunised child for the intervention was approximately eight times higher than usual care (low‐certainty evidence). No included studies reported outcomes associated with parents’ experience of the intervention (e.g. satisfaction).Authors' conclusionsThere is low‐ to moderate‐certainty evidence suggesting that face‐to‐face information or education may improve or slightly improve children's vaccination status, parents' knowledge, and parents' intention to vaccinate.Face‐to‐face interventions may be more effective in populations where lack of awareness or understanding of vaccination is identified as a barrier (e.g. where people are unaware of new or optional vaccines). The effect of the intervention in a population where concerns about vaccines or vaccine hesitancy is the primary barrier is less clear. Reliable and validated scales for measuring more complex outcomes, such as attitudes or beliefs, are necessary in order to improve comparisons of the effects across studies.
    1. BackgroundImmunization rates for children and adults are rising, but coverage levels have not reached optimal goals. As a result, vaccine‐preventable diseases still occur. In an era of increasing complexity of immunization schedules, rising expectations about the performance of primary care, and large demands on primary care providers, it is important to understand and promote interventions that work in primary care settings to increase immunization coverage. One common theme across immunization programs in many nations involves the challenge of implementing a population‐based approach and identifying all eligible recipients, for example the children who should receive the measles vaccine. However, this issue is gradually being addressed through the availability of immunization registries and electronic health records. A second common theme is identifying the best strategies to promote high vaccination rates. Three types of strategies have been studied: (1) patient‐oriented interventions, such as patient reminder or recall, (2) provider interventions, and (3) system interventions, such as school laws. One of the most prominent intervention strategies, and perhaps best studied, involves patient reminder or recall systems. This is an update of a previously published review.ObjectivesTo evaluate and compare the effectiveness of various types of patient reminder and recall interventions to improve receipt of immunizations.Search methodsWe searched CENTRAL, MEDLINE, Embase and CINAHL to January 2017. We also searched grey literature and trial registers to January 2017.Selection criteriaWe included randomized trials, controlled before and after studies, and interrupted time series evaluating immunization‐focused patient reminder or recall interventions in children, adolescents, and adults who receive immunizations in any setting. We included no‐intervention control groups, standard practice activities that did not include immunization patient reminder or recall, media‐based activities aimed at promoting immunizations, or simple practice‐based awareness campaigns. We included receipt of any immunizations as eligible outcome measures, excluding special travel immunizations. We excluded patients who were hospitalized for the duration of the study period.Data collection and analysisWe used the standard methodological procedures expected by Cochrane and the Cochrane Effective Practice and Organisation of Care (EPOC) Group. We present results for individual studies as relative rates using risk ratios, and risk differences for randomized trials, and as absolute changes in percentage points for controlled before‐after studies. We present pooled results for randomized trials using the random‐effects model.Main resultsThe 75 included studies involved child, adolescent, and adult participants in outpatient, community‐based, primary care, and other settings in 10 countries.Patient reminder or recall interventions, including telephone and autodialer calls, letters, postcards, text messages, combination of mail or telephone, or a combination of patient reminder or recall with outreach, probably improve the proportion of participants who receive immunization (risk ratio (RR) of 1.28, 95% confidence interval (CI) 1.23 to 1.35; risk difference of 8%) based on moderate certainty evidence from 55 studies with 138,625 participants.Three types of single‐method reminders improve receipt of immunizations based on high certainty evidence: the use of postcards (RR 1.18, 95% CI 1.08 to 1.30; eight studies; 27,734 participants), text messages (RR 1.29, 95% CI 1.15 to 1.44; six studies; 7772 participants), and autodialer (RR 1.17, 95% CI 1.03 to 1.32; five studies; 11,947 participants). Two types of single‐method reminders probably improve receipt of immunizations based on moderate certainty evidence: the use of telephone calls (RR 1.75, 95% CI 1.20 to 2.54; seven studies; 9120 participants) and letters to patients (RR 1.29, 95% CI 1.21 to 1.38; 27 studies; 81,100 participants).Based on high certainty evidence, reminders improve receipt of immunizations for childhood (RR 1.22, 95% CI 1.15 to 1.29; risk difference of 8%; 23 studies; 31,099 participants) and adolescent vaccinations (RR 1.29, 95% CI 1.17 to 1.42; risk difference of 7%; 10 studies; 30,868 participants). Reminders probably improve receipt of vaccinations for childhood influenza (RR 1.51, 95% CI 1.14 to 1.99; risk difference of 22%; five studies; 9265 participants) and adult influenza (RR 1.29, 95% CI 1.17 to 1.43; risk difference of 9%; 15 studies; 59,328 participants) based on moderate certainty evidence. They may improve receipt of vaccinations for adult pneumococcus, tetanus, hepatitis B, and other non‐influenza vaccinations based on low certainty evidence although the confidence interval includes no effect of these interventions (RR 2.08, 95% CI 0.91 to 4.78; four studies; 8065 participants).Authors' conclusionsPatient reminder and recall systems, in primary care settings, are likely to be effective at improving the proportion of the target population who receive immunizations.
    1. BackgroundAlthough vaccination has been proved to be a safe, efficacious, and cost-effective intervention, immunisation rates remain suboptimal in many European countries, resulting in poor control of many vaccine-preventable diseases.DiscussionThe Summit of Independent European Vaccination Experts focused on the perception of vaccines and vaccination by the general public and healthcare professionals and discussed ways to improve vaccine uptake in Europe.Despite the substantial impact and importance of the media, healthcare professionals were identified as the main advocates for vaccination and the most important source of information about vaccines for the general public. Healthcare professionals should receive more support for their own education on vaccinology, have rapid access to up-to-date information on vaccines, and have easy access to consultation with experts regarding vaccination-related problems. Vaccine information systems should be set up to facilitate promotion of vaccination.SummaryEvery opportunity to administer vaccines should be used, and active reminder systems should be set up. A European vaccine awareness week should be established.
    1. Public trust in the safety and efficacy of vaccines is one key to the remarkable success of immunization programs within the United States and globally. Allegations of harm from vaccination have raised parental, political, and clinical anxiety to a level that now threatens the ability of children to receive timely, full immunization. Multiple factors have contributed to current concerns, including the interdependent issues of an evolving communications environment and shortfalls in structure and resources that constrain research on immunization safety (immunization-safety science). Prompt attention by public health leadership to spreading concern about the safety of immunization is essential for protecting deserved public trust in immunization.
    1. The incidence, prevalence, morbidity and mortality rates of vaccine-preventable diseases have decreased drastically since the advent of modern vaccination by Edward Jenner at the end of the 18th century. In recent years, however, a growing number of parents have been refusing or delaying vaccination for their children for socioeconomical, medical, religious and/or philosophical reasons. This has resulted in a loss of herd immunity that has caused a resurgence of many infectious diseases. This article describes evidence-based methods by which a pediatric clinic can become a vaccine champion by aiming at vaccination rates of 100 percent. This goal can be attained by a team effort that addresses the challenges of vaccination by using every visit as a chance to vaccinate, educate, address the fears and the concerns of the parents and provide articles and other written documentations on the benefits and side effects of vaccines. A standardized system that identifies and tracks patients who need vaccines is also essential to find those who are seldom brought to medical attention. A consistent and systematic use of these evidence-based methods by a dedicated staff is essential to attain vaccination rates close to 100 percent.
    1. This is the first in a series of two articles about childhood and adult immunization in the United States. Part 2 will discuss adult vaccination, the role of pharmacists, and considerations for P&T committees.
    1. Background: Vaccination hesitancy and skepticism among parents hinders progress in achieving full vaccination coverage. Swedish measles, mumps and rubella (MMR) vaccine coverage is high however some areas with low vaccination coverage risk outbreaks. This study aimed to explore factors influencing the decision of Somali parents living in the Rinkeby and Tensta districts of Stockholm, Sweden, on whether or not to vaccinate their children with the measles, mumps and rubella (MMR) vaccine. Method: Participants were 13 mothers of at least one child aged 18 months to 5 years, who were recruited using snowball sampling. In-depth interviews were conducted in Somali and Swedish languages and the data generated was analysed using qualitative content analysis. Both written and verbal informed consent were obtained from participants. Results: Seven of the mothers had not vaccinated their youngest child at the time of the study and decided to postpone the vaccination until their child became older (delayers). The other six mothers had vaccinated their child for MMR at the appointed time (timely vaccinators). The analysis of the data revealed two main themes: (1) barriers to vaccinate on time, included issues surrounding fear of the child not speaking and unpleasant encounters with nurses and (2) facilitating factors to vaccinate on time, included heeding vaccinating parents’ advice, trust in nurses and trust in God. The mothers who had vaccinated their children had a positive impact in influencing other mothers to also vaccinate. Conclusions: Fear, based on the perceived risk that vaccination will lead to autism, among Somali mothers in Tensta and Rinkeby is evident and influenced by the opinions of friends and relatives. Child Healthcare Center nurses are important in the decision-making process regarding acceptance of MMR vaccination. There is a need to address mothers’ concerns regarding vaccine safety while improving the approach of nurses as they address these concerns.
    1. U.S. media reports suggest that vastly disproportionate numbers of un‐ and under‐vaccinated children attend Waldorf (private alternative) schools. After confirming this statistically, I analyzed qualitative and quantitative vaccination‐related data provided by parents from a well‐established U.S. Waldorf school. In Europe, Waldorf‐related non‐vaccination is associated with anthroposophy (a worldview foundational to Waldorf education)—but that was not the case here. Nor was simple ignorance to blame: Parents were highly educated and dedicated to self‐education regarding child health. They saw vaccination as variously unnecessary, toxic, developmentally inappropriate, and profit driven. Some vaccine caution likely predated matriculation, but notable post‐enrollment refusal increases provided evidence of the socially cultivated nature of vaccine refusal in the Waldorf school setting. Vaccine caution was nourished and intensified by an institutionalized emphasis on alternative information and by school community norms lauding vaccine refusal and masking uptake. Implications for intervention are explored.
    1. With the successful development and distribution of new vaccines, there is hope in the United States that the acute phase of the SARS-CoV-2 pandemic may soon end. 
    1. A surge of attacks in one of Canada’s most multicultural cities during the pandemic is surfacing long-simmering racial tensions.
    1. Even with vaccines, many older people and their relatives are weighing how to manage at-home care for those who can no longer live independently.
    1. Slovakia conducted multiple rounds of population-wide rapid antigen testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in late 2020, combined with a period of additional contact restrictions. Observed prevalence decreased by 58% (95% confidence interval: 57 to 58%) within 1 week in the 45 counties that were subject to two rounds of mass testing, an estimate that remained robust when adjusting for multiple potential confounders. Adjusting for epidemic growth of 4.4% (1.1 to 6.9%) per day preceding the mass testing campaign, the estimated decrease in prevalence compared with a scenario of unmitigated growth was 70% (67 to 73%). Modeling indicated that this decrease could not be explained solely by infection control measures but required the addition of the isolation and quarantine of household members of those testing positive.
    1. The tempo-spatial patterns of Covid-19 infections are a result of nested personal, societal, and political decisions that involve complicated epidemiological dynamics across overlapping spatial scales. High infection “hotspots” interspersed within regions where infections remained sporadic were ubiquitous early in the outbreak, but the spatial signature of the infection evolved to affect most regions equally, albeit with distinct temporal patterns. The sparseness of Covid-19 infections in the United States was analyzed at scales spanning from 10 to 2,600 km (county to continental scale). Spatial evolution of Covid-19 cases in the United States followed multifractal scaling. A rapid increase in the spatial correlation was identified early in the outbreak (March to April). Then, the increase continued at a slower rate and approached the spatial correlation of human population. Instead of adopting agent-based models that require tracking of individuals, a kernel-modulated approach is developed to characterize the dynamic spreading of disease in a multifractal distributed susceptible population. Multiphase Covid-19 epidemics were reasonably reproduced by the proposed kernel-modulated susceptible–infectious–recovered (SIR) model. The work explained the fact that while the reproduction number was reduced due to nonpharmaceutical interventions (e.g., masks, social distancing, etc.), subsequent multiple epidemic waves still occurred; this was due to an increase in susceptible population flow following a relaxation of travel restrictions and corollary stay-at-home orders. This study provides an original interpretation of Covid-19 spread together with a pragmatic approach that can be imminently used to capture the spatial intermittency at all epidemiologically relevant scales while preserving the “disordered” spatial pattern of infectious cases.
    1. All medical treatments have potential harms as well as potential benefits, and it's important to be able to weigh these against each other. With vaccines, the benefits are particularly complex as they can involve benefits to others as well as to ourselves - and the harms can feel particularly acute because we take vaccines when we are healthy, as a preventative measure.With the initial release of data from the MHRA on a specific type of blood clot recorded in the UK that might be associated with the Astra-Zeneca COVID-19 vaccine, the Winton Centre were asked to help communicate the risks. Now more data is available, we have updated our graphics.The blood-clot estimates are based on the MHRA’s yellow-card reports and so they have uncertainty around them, both because the small number of events mean there is uncertainty about the underlying risk, and that cases may yet to be reported. With very rare events like this we expect the rates to fluctuate as more data comes in so it’s not surprising to see changes from week to week.
    1. Journals risk being used in place of regulators when they publish studies of novel vaccines that have not yet been authorised by a major regulator. Chris van Tulleken argues that peer review is inadequate to decide the risk-benefit ratio of new drugsIn August 2020 President Vladimir Putin announced Sputnik V, a vaccine developed by Russia’s Gamaleya National Center of Epidemiology and Microbiology. The president’s claim that it had gone through “all the necessary trials”1 did not seem to be backed up by the information on the Russian language registration certificate, which said that just 38 participants had received the vaccine.2International responses ranged from concern to derision. By granting approval to a vaccine before results from large phase III randomised trials were available, the Russian government seemed to be taking two immense risks. The first was a risk of direct harm to large numbers of people. Bad vaccines don’t just fail to protect, they might have serious adverse effects including making subsequent infection more dangerous through antibody associated disease enhancement, a phenomenon previously seen with SARS and MERS coronaviruses.3 Second, if people were harmed, public confidence in the vaccination programme and future investment in covid-19 vaccine development and uptake might be jeopardised. Trust in vaccines is easily bruised and recovers slowly.In September 2020, the first peer reviewed Sputnik V data were published in the Lancet: two non-randomised, open label studies, each of 38 people. No serious adverse events were reported, and the vaccine seemed to induce robust immune responses in participants.4

    1. If you are pregnant, you can receive a COVID-19 vaccine. There is currently no evidence that any vaccines, including COVID-19 vaccines, cause fertility problems. However, data are limited about the safety of COVID-19 vaccines for people who are pregnant. CDC established the v-safe COVID-19 Vaccine Pregnancy Registry to learn more about this issue. The registry is collecting health information from people who received COVID-19 vaccination in the periconception period (within 30 days before last menstrual period) or during pregnancy. The information is critical to helping people and their healthcare providers make informed decisions about COVID-19 vaccination. Participation is voluntary, and participants may opt out at any time.
    1. Vaccine hesitancy could undermine efforts to control COVID-19. We investigated the prevalence of COVID-19 vaccine hesitancy in the UK and identified vaccine hesitant subgroups. The ‘Understanding Society’ COVID-19 survey asked participants (n = 12,035) their likelihood of vaccine uptake and reason for hesitancy. Cross-sectional analysis assessed vaccine hesitancy prevalence and logistic regression calculated odds ratios. Overall vaccine hesitancy was low (18% unlikely/very unlikely). Vaccine hesitancy was higher in women (21.0% vs 14.7%), younger age groups (26.5% in 16–24 year olds vs 4.5% in 75 + ) and those with lower education levels (18.6% no qualifications vs 13.2% degree qualified). Vaccine hesitancy was high in Black (71.8%) and Pakistani/Bangladeshi (42.3%) ethnic groups. Odds ratios for vaccine hesitancy were 13.42 (95% CI:6.86, 26.24) in Black and 2.54 (95% CI:1.19, 5.44) in Pakistani/Bangladeshi groups (compared to White British/Irish) and 3.54 (95% CI:2.06, 6.09) for people with no qualifications versus degree. Urgent action to address hesitancy is needed for some but not all ethnic minority groups.
    1. There is huge variation in the percentage of frontline NHS healthcare staff who have been vaccinated against Covid in England.More than 98% in the North East and South West have had a first dose - but only 79% in London, leaving around 35,000 staff unvaccinated there.Ministers are considering whether to make the jab mandatory for NHS staff.Health and social care workers across the UK were one of the first groups to be offered a vaccine. In England, NHS data suggests 93% of eligible frontline staff have been vaccinated - equivalent to one million doses. But, nearly three months after the vaccination programme began, up to 80,000 frontline staff have still not taken up the offer.
    1. Among widespread calls for a public inquiry into England’s response to the covid-19 pandemic, the King’s Fund has proposed a potential framework for an inquiry under five key headings: “Intrinsic risk,” “Public health response,” “Healthcare system response,” “Measures in wider society,” and “Adult social care response.”1 All partly depend on the role of government and its agencies. I realise that a public inquiry can produce an evidenced narrative and recommendations, but the need and demand for one highlights a serious failure of open elected government and leadership at the highest levels.
    1. Since vaccines to prevent the spread of COVID-19 were first approved only months ago, more than 40% of people living in the United States have received at least one dose. But in nations like Mozambique, Namibia, and Sudan, that number is closer to 2%. So far, the World Health Organization’s vaccine-sharing initiative, COVAX, has failed to close the gap.  President Biden recently came out in support of international efforts to convince the World Health Organization to lift intellectual property restrictions in order to allow local manufacturers to produce generic versions of the life-saving drugs.
    1. Vaccine regulators have delivered a clear verdict: In most settings, the benefits of the COVID-19 vaccines made by AstraZeneca and Johnson & Johnson (J&J) far outweigh the small risk they will cause an unusual and sometimes deadly clotting disorder. But many questions remain about who is most at risk, how the risk-benefit calculus changes when cases fall, and what the side effects mean for the future of these vaccines, which use adenoviruses to ferry the gene for SARS-CoV-2’s spike protein into human cells.
    1. Does boredom increase risk behaviors in real-world settings, and if so, might it contribute to failure to comply with public health guidelines during the COVID-19 pandemic? In a large cross-national sample of 63,336 community respondents from 116 countries, we examined the prevalence of lockdown-related boredom during the initial outbreak of COVID-19, as well as its demographic and situational predictors. Boredom was higher in countries with more COVID-19 cases, more stringent lockdown policies, and lower GDPs, as well as among men and less educated/younger adults. Additionally, we examined whether “pandemic boredom” predicted longitudinal decreases in social distancing behavior (and vice versa; n = 8031). We found little evidence that changes in boredom predict individual public health behaviors (handwashing, staying home, self-quarantining, avoiding crowds) over time, or that such behaviors had any reliable longitudinal effects on boredom itself. In summary, we found little evidence that boredom affects pandemic health behaviors.
    1. Parents have experienced considerable challenges and stress during the COVID-19 pandemic, which may impact their well-being. This meta-analysis sought to identify: 1) the prevalence of depression and anxiety in parents of young children (< age 5) during the COVID-19 pandemic, and 2) sociodemographic (e.g., parent age, minority status) and methodological moderators (e.g., study quality) that explain heterogeneity among studies. A systematic search was conducted across four databases from January 1st, 2020 to March 3st, 2021. A total of 18 non-overlapping studies (9,101 participants), all focused on maternal mental health, met inclusion criteria. Random-effect meta-analyses were conducted. Pooled prevalence estimates for clinically significant depression and anxiety symptoms for mothers of young children during the COVID-19 pandemic were 27.4% (95% CI: 21.5-34.3) and 43.5% (95% CI:27.5-60.9), respectively. Prevalence of clinically elevated depression and anxiety symptoms were higher in Europe and North America and among older mothers. Clinically elevated depressive symptoms were lower in studies with a higher percentage of racial and ethnic minority individuals. In comparison, clinically elevated anxiety symptoms were higher among studies of low study quality and in samples with highly educated mothers. Policies and resources targeting improvements in maternal mental health are essential.
    1. Risk occupies a central role in both the theory and practice of decision-making. Although it is deeply implicated in many conditions involving dysfunctional behavior and thought, modern theoretical approaches to understanding and mitigating risk, in either one-shot or sequential settings, have yet to permeate fully the fields of neural reinforcement learning and computational psychiatry. Here we use one prominent approach, called conditional value-at-risk (CVaR), to examine optimal risk-sensitive choice and one form of optimal, risk-sensitive offline planning. We relate the former to both a justified form of the gambler’s fallacy and extremely risk-avoidant behavior resembling that observed in anxiety disorders. We relate the latter to worry and rumination.
    1. Nonpharmaceutical interventions to control SARS-CoV-2 spread have been implemented with different intensity, timing, and impact on transmission. As a result, post-lockdown COVID-19 dynamics are heterogeneous and difficult to interpret. We describe a set of contact surveys performed in four Chinese cities (Wuhan, Shanghai, Shenzhen, and Changsha) during the pre-pandemic, lockdown and post-lockdown periods to quantify changes in contact patterns. In the post-lockdown period, the mean number of contacts increased by 5 to 17% as compared to the lockdown period. However, it remains three to seven times lower than its pre-pandemic level sufficient to control SARS-CoV-2 transmission. We find that the impact of school interventions depends nonlinearly on the intensity of other activities. When most community activities are halted, school closure leads to a 77% decrease in the reproduction number; in contrast, when social mixing outside of schools is at pre-pandemic level, school closure leads to a 5% reduction in transmission.
    1. The US has backed India and South Africa's bid to temporarily lift patent protection for COVID-19 vaccines. The support for an IP waiver by the WTO has left pharma companies dismayed and health activists asking for more.
    1. Viruses need entry proteins to penetrate the cells where they will replicate. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) version is called the spike or S protein. The S protein, also the target of the current vaccines, is quickly adapting to its new human hosts. It took its first major step in this direction early in 2020, when its amino acid 614 (of 1297) changed from an aspartic acid (D) to a glycine (G). Viruses bearing this D614G mutation transmit among humans more rapidly and now form the majority in circulation
    1. As of early April, 2021, more than 2·8 million individuals have died globally from COVID-19. However, tens of millions of patients have survived COVID-19 and returned to everyday life. Increasing evidence has shown that a considerable proportion of patients did not recover fully and had lasting sequelae, described by various terms without consensus, including long COVID, post-COVID condition or syndrome, postacute (or late) sequelae of COVID-19, and post-acute COVID syndrome.1Lerner AM Robinson DA Yang L et al.Toward understanding COVID-19 recovery: National Institutes of Health workshop on postacute COVID-19.Ann Intern Med. 2021; (published online March 30.)https://doi.org/10.7326/M21-1043Crossref PubMed Google Scholar,  2Nalbandian A Sehgal K Gupta A et al.Post-acute COVID-19 syndrome.Nat Med. 2021; 27: 601-615Crossref PubMed Scopus (1) Google Scholar Studies have mainly focused on patients with COVID-19 after hospital admission.3Huang C Huang L Wang Y et al.6-month consequences of COVID-19 in patients discharged from hospital: a cohort study.Lancet. 2021; 397: 220-232Summary Full Text Full Text PDF PubMed Scopus (51) Google Scholar,  4Morin L Savale L Pham T et al.Four-month clinical status of a cohort of patients after hospitalization for COVID-19.JAMA. 2021; (published online March 17.)https://doi.org/10.1001/jama.2021.3331PubMed Google Scholar One study with a small sample size and without a control group of people without COVID-19 described the long-term outcomes of patients with COVID-19 who did not require hospital admission.5Stavem K Ghanima W Olsen MK Gilboe HM Einvik G Persistent symptoms 1·5–6 months after COVID-19 in non-hospitalised subjects: a population-based cohort study.Thorax. 2020; 76: 405-407Crossref Scopus (8) Google Scholar
    1. A form of the coronavirus variant first identified in India, which is now spreading in the UK, appears to be passed on at least as easily as the “Kent variant” that now dominates UK infections. The variant, called B.1.617.2, was designated a “variant of concern” on 7 May by health authorities in England. B.1.617.2 is one of three sub-lineages of B.1.617, the variant that has become common in India and which some have considered, but not proven, to be one potential factor behind the crisis India has been facing. On 10 May, the World Health Organization designated B.1.617 as a variant of concern. Advertisement googletag.cmd.push(function() { googletag.display('mpu-mid-article'); }); googletag.cmd.push(function() { googletag.display('video-mid-article'); }); Public Health England (PHE) has moderate confidence that the B.1.617.2 variant is on a par for transmissibility with B.1.1.7, which originated in the UK, said Sharon Peacock at the University of Cambridge at a press briefing today. The view is based on the variant’s mutations and its ability to circulate in the UK alongside the Kent variant. However, there is still much we don’t know about the Indian variants.
    1. OBJECTIVE: To explore public attitudes to COVID-19 vaccines in the UK, focused on intentions and decisions around taking vaccines, views on ‘vaccine passports’, and experiences and perspectives on post-vaccination behaviour. DESIGN: Qualitative study consisting of 6 online focus groups conducted between 15th March – 22nd April 2021. SETTING: Online video conferencing PARTICIPANTS: 29 adult UK-based participants RESULTS: Three main groups regarding participants’ decision or intention to receive a COVID-19 vaccine were identified: (1) Accepters, (2) Delayers and (3) Refusers. Two reasons for vaccine delay were identified: delay due to a perceived need more information and delay until vaccine was “required” in the future. Three main facilitators (Vaccination as a social norm; Vaccination as a necessity; Trust in science) and six barriers (Preference for “natural immunity”; Concerns over possible side effects; Distrust in government; Perceived lack of information; Conspiracy theories; “Covid echo chambers”) to vaccine uptake were identified. For some delayers, 'vaccine passports' were perceived to be a reason why they would get vaccinated in the future. However, vaccine passports were controversial, and were framed in four main ways: as “a necessary evil”; as “Orwellian”; as a “human rights problem”; and as a source of confidence”. Participants generally felt that receiving a vaccine was not changing the extent to which people were adhering to COVID-19 measures. CONCLUSIONS: Overall positive sentiment around vaccines is high. However, there remains a number of potential barriers which might be leading to vaccine delay in some. ‘Vaccine delay’ might be a more useful and precise construct than vaccine hesitancy in explaining why some may initially ignore or be uncertain about vaccination invitations. Vaccine passports may increase or ‘nudge’ uptake in some delayers but may be unpopular in others. Earlier concerns that vaccination might reduce adherence to social distancing measures are not borne out in our data, with most people reporting adherence and caution.
    1. Interacting with others wearing a face mask has become a regular worldwide practice since the beginning of the COVID-19 pandemic. However, the impact of face masks on cognitive mechanisms supporting social interaction is still largely unexplored. In the present work we focused on gaze cueing of attention, a phenomenon tapping the essential ability which allows individuals to orient their attentional resources in response to eye gaze signals coming from others. Participants from both a Western (i.e., Italy; Experiment 1) and an Asian (i.e., China; Experiment 2) country were involved, namely two countries in which the daily use of face masks before COVID-19 pandemic was either extremely uncommon or frequently adopted, respectively. Both samples completed a task in which a peripheral target had to be discriminated while a task irrelevant averted gaze face, wearing a mask or not, acted as a central cueing stimulus. Overall, a reliable and comparable gaze cueing emerged in both experiments, independent of the mask condition. These findings suggest that social attention is preserved even when the person perceived is wearing a face mask.
    1. The German government said while they support global vaccine supplies, "the protection of intellectual property is a source of innovation and must remain so in the future."
    1. Distance clouds perspective. The covid-19 pandemic is in a dangerous new phase, ripping through Brazil and India, two of the world’s emerging powers, with all middle and low income countries at risk. Neither country achieved herd immunity, as some politicians and scientists recklessly claimed. Yet the scale of death and fear feels distant from the UK. It shouldn’t. Just as the effects of environmental damage shouldn’t feel distant either. They already affect us directly.1 These aren’t merely other people’s problems. It is this “othering” that precipitated the failed pandemic responses of the UK, US, and much of Europe. Any isolationism or exceptionalism we sow today will reap a future harvest of premature death and worse health.
    1. Could today’s version of America have been able to win World War II? It hardly seems possible.That victory required national cohesion, voluntary sacrifice for the common good and trust in institutions and each other. America’s response to Covid-19 suggests that we no longer have sufficient quantities of any of those things. window.onload = function () { const target = document.querySelector('#push-signup'); const options = { channel: 'david-brooks', region: 'top-banner', productCode: 'PUDB', channelName: 'David Brooks', ctaMsg: 'Get alerts when we publish', subscribedMsg: 'You’re signed up to receive alerts from', }; const config = { target, options, }; pushSignup(config); }; In 2020 Americans failed to socially distance and test for the coronavirus and suffered among the highest infection and death rates in the developed world. Millions decided that wearing a mask infringed their individual liberty.
    1. A confusing and unusually nasty fight broke out this week over the safety of a Russian COVID-19 vaccine known as Sputnik V after a Brazilian health agency declined on Monday to authorize its import because of quality and safety concerns. The stakes escalated yesterday when the Twitter account officially associated with the vaccine said “Sputnik V is undertaking a legal defamation proceeding” against Brazil’s regulators. In an online press conference several hours later, the Brazilian Health Regulatory Agency (Anvisa) defended its decision, maintaining that documentation from some of the Russian facilities making Sputnik V shows that one of its two doses contains adenoviruses capable of replication, a potential danger to vaccine recipients. The vaccine uses two different adenoviruses, which cause the common cold, to deliver the gene for the spike protein of SARS-CoV-2, the virus that causes COVD-19. Both are supposed to be stripped of a key gene that allows them to replicate.
    1. There are a lot of ways Dr. Kent Bream would describe the lines of people waiting, sometimes for hours, for COVID-19 vaccines at his community health clinic in West Philadelphia. Eager. Impatient. Frustrated, even. But "hesitant" doesn't come to mind. As soon as the city started sending him doses, he says, demand was never an issue. In fact, Bream's clinic — which is located in a predominantly Black neighborhood — had more vaccines than it had staff to administer them. "I said, send me vaccine and I will show you that there is not the level of vaccine hesitancy you think there is," recalls the medical director of Sayre Health Center. Despite the high demand, the latest data show that 23% of vaccines are going to Black residents. Compare that to Philadelphia's total population, which is more than 40% Black. Vaccination rates for Black and Latino people in the city are still half what they are for whites.
    1. We investigated laypersons’ agreement with technical claims about the spread of the Sars-CoV-2 virus and with claims about the risk from COVID-19 in the general public in Germany (N = 1,575) and compared these with the evaluations of scientific experts (N = 128). Using Latent Class Analysis, we distinguished four segments in the general public. Two groups (mainstream and cautious, 73%) are generally consistent with scientific experts in their evaluations. Two groups (doubters and deniers, 27%) differ distinctively from expert evaluations and tend to believe in conspiracies about COVID-19. Deniers (8%) are characterized by low risk assessments, anti-elitist sentiments and low compliance with containment measures. Doubters (19%) are characterized by general uncertainty in the distinction between true and false claims and by low scientific literacy in terms of cognitive ability and style. Our research indicates that conspiracy beliefs about COVID-19 cannot be linked to a single and distinct motivational structure.
    1. Two studies showed the vaccine to be more than 95 percent effective at protecting against severe disease or death from the variants first identified in South Africa and the U.K.
    1. Fake news, like conjuring, plays on our weaknesses — but with a little attention, we can fight back
    1. In psychology, causal inference—both the transport from lab estimates to the real world and estimation on the basis of observational data—is often pursued in a casual manner. Underlying assumptions remain unarticulated; potential pitfalls are compiled in post-hoc lists of flaws. The field should move on to coherent frameworks of causal inference and generalizability that have been developed elsewhere.
    1. When situations occur in which unwanted events are rightly or wrongly connected with vaccination, they may erode confidence in vaccines and the authorities delivering them. This document presents the scientific evidence behind WHO’s recommendations on building and restoring confidence in vaccines and vaccination, both in ongoing work and during crises. The evidence draws on a vast reserve of laboratory research and fieldwork within psychology and communication. It examines how people make decisions about vaccination; why some people are hesitant about vaccination; and the factors that drive a crisis, covering how building trust, listening to and understanding people, building relations, communicating risk and shaping messages to the audiences may mitigate crises. This document provides a knowledge base for stakeholders who develop communication strategies or facilitate workshops on communication and trust-building activities in relation to vaccines and immunization, such as immunization programme units, ministries of health, public relations and health promotion units, vaccine safety communication trainers and immunization advisory bodies
    1. BackgroundIn high-income countries, substantial differences exist in vaccine uptake relating to socioeconomic status, gender, ethnic group, geographic location and religious belief. This paper updates a 2009 systematic review on effective interventions to decrease vaccine uptake inequalities in light of new technologies applied to vaccination and new vaccine programmes (eg, human papillomavirus in adolescents).MethodsWe searched MEDLINE, Embase, ASSIA, The Campbell Collaboration, CINAHL, The Cochrane Database of Systematic Reviews, Eppi Centre, Eric and PsychINFO for intervention, cohort or ecological studies conducted at primary/community care level in children and young people from birth to 19 years in OECD countries, with vaccine uptake or coverage as outcomes, published between 2008 and 2015.ResultsThe 41 included studies evaluated complex multicomponent interventions (n=16), reminder/recall systems (n=18), outreach programmes (n=3) or computer-based interventions (n=2). Complex, locally designed interventions demonstrated the best evidence for effectiveness in reducing inequalities in deprived, urban, ethnically diverse communities. There is some evidence that postal and telephone reminders are effective, however, evidence remains mixed for text-message reminders, although these may be more effective in adolescents. Interventions that escalated in intensity appeared particularly effective. Computer-based interventions were not effective. Few studies targeted an inequality specifically, although several reported differential effects by the ethnic group.ConclusionsLocally designed, multicomponent interventions should be used in urban, ethnically diverse, deprived populations. Some evidence is emerging for text-message reminders, particularly in adolescents. Further research should be conducted in the UK and Europe with a focus on reducing specific inequalities.
    1. IntroductionBeyond their impact on health, vaccines can lead to large economic benefits. While most economic evaluations of vaccines have focused on the health impact of vaccines at a national scale, it is critical to understand how their impact is distributed along population subgroups.MethodsWe build a financial risk protection model to evaluate the impact of immunisation against measles, severe pneumococcal disease and severe rotavirus for birth cohorts vaccinated over 2016–2030 for three scenarios in 41 Gavi-eligible countries: no immunisation, current immunisation coverage forecasts and the current immunisation coverage enhanced with funding support. We distribute modelled disease cases per socioeconomic group and derive the number of cases of: (1) catastrophic health costs (CHCs) and (2) medical impoverishment.ResultsIn the absence of any vaccine coverage, the number of CHC cases attributable to measles, severe pneumococcal disease and severe rotavirus would be approximately 18.9 million, 6.6 million and 2.2 million, respectively. Expanding vaccine coverage would reduce this number by up to 90%, 30% and 40% in each case. More importantly, we find a higher share of CHC incidence among the poorest quintiles who consequently benefit more from vaccine expansion.ConclusionOur findings contribute to the understanding of how vaccines can have a broad economic impact. In particular, we find that immunisation programmes can reduce the proportion of households facing catastrophic payments from out-of-pocket health expenses, mainly in lower socioeconomic groups. Thus, vaccines could have an important role in poverty reduction.
    1. In the World Health Organization (WHO) European Region, differences in uptake rates of routine childhood immunisation persist within and among countries, with rates even falling in some areas. There has been a tendency among national programmes, policymakers and the media in recent years to attribute missed vaccinations to faltering demand or refusal among parents. However, evidence shows that the reasons for suboptimal coverage are multifactorial and include the social determinants of health. At the midpoint in the implementation of the European Vaccine Action Plan 2015–2020 (EVAP), national immunisation programmes should be aware that inequity may be a factor affecting their progress towards the EVAP immunisation targets. Social determinants of health, such as individual and household income and education, impact immunisation uptake as well as general health outcomes – even in high-income countries. One way to ensure optimal coverage is to make inequities in immunisation uptake visible by disaggregating immunisation coverage data and linking them with already available data sources of social determinants. This can serve as a starting point to identify and eliminate underlying structural causes of suboptimal uptake. The WHO Regional Office for Europe encourages countries to make the equitable delivery of vaccination a priority.
    1. Background Cervical cancer disproportionately affects women from lower socioeconomic backgrounds. A human papillomavirus (HPV) vaccination programme was introduced in Scotland in 2008 with uptake being lower and inequitable in a catch-up cohort run for the first three years of the programme compared with the routine programme. The socioeconomic differences in vaccine uptake have the potential to further increase the inequality gap in regards to cervical disease.Methods Vaccination status was linked to demographic, cytological and colposcopic data, which are routinely collected by the Scottish HPV surveillance system. Incidence rates and relative risk of cervical intraepithelial neoplasia (CIN) 1, 2 and 3 in unvaccinated and vaccinated women were stratified by birth year and deprivation status using Poisson regression.Results Women who received three doses of HPV vaccine have significantly decreased risk of CIN 1, 2 and 3. Vaccine effectiveness was greater in those women from the most deprived backgrounds against CIN 2 and 3 lesions. Compared with the most deprived, unvaccinated women, the relative risk of CIN 3 in fully vaccinated women in the same deprivation group was 0.29 (95% CI 0.2 to 0.43) compared with 0.62 (95% CI 0.4 to 0.97) in vaccinated women in the least-deprived group.Conclusions The HPV vaccine is associated with significant reductions in both low-grade and high-grade CIN for all deprivation categories. However, the effect on high-grade disease was most profound in the most-deprived women. These data are welcoming and allay the concern that inequalities in cervical cancer may persist or increase following the introduction of the vaccine in Scotland.
    1. The problem of antimicrobial resistance (AMR) and the associated morbidity and mortality due to antibiotic resistant bacterial pathogens is not new. However, AMR has been increasing at an alarming rate with appearances of diseases caused by bacteria exhibiting resistance to not just one but multiple classes of antibiotics. The World Health Organization (WHO) supported by governments, health ministries and health agencies has formulated global action plans to combat the rise in AMR, supporting a number of proven initiatives such as antimicrobial stewardship, investments in development of new classes of antibiotics, and educational programs designed to eliminate inappropriate antibiotic use. Vaccines as tools to reduce AMR have historically been under-recognized, yet the positive effect in reducing AMR has been well established. For example Haemophilus influenzae type B (Hib) as well as Streptococcus pneumoniae (pneumococcal) conjugate vaccines have impressive track records in not only preventing life threatening diseases caused by these bacteria, but also reducing antibiotic use and AMR. This paper will describe the drivers of antibiotic use and subsequent development of AMR; it will make the case how existing vaccines are already participating in combatting AMR, describe future prospects for the role of new vaccines in development to reduce AMR, and highlight challenges associated with future vaccine development to combat AMR.
    1. In low-income countries, infectious diseases still account for a large proportion of deaths, highlighting health inequities largely caused by economic differences. Vaccination can cut health-care costs and reduce these inequities. Disease control, elimination or eradication can save billions of US dollars for communities and countries. Vaccines have lowered the incidence of hepatocellular carcinoma and will control cervical cancer. Travellers can be protected against “exotic” diseases by appropriate vaccination. Vaccines are considered indispensable against bioterrorism. They can combat resistance to antibiotics in some pathogens. Noncommunicable diseases, such as ischaemic heart disease, could also be reduced by influenza vaccination.Immunization programmes have improved the primary care infrastructure in developing countries, lowered mortality in childhood and empowered women to better plan their families, with consequent health, social and economic benefits.Vaccination helps economic growth everywhere, because of lower morbidity and mortality. The annual return on investment in vaccination has been calculated to be between 12% and 18%. Vaccination leads to increased life expectancy. Long healthy lives are now recognized as a prerequisite for wealth, and wealth promotes health. Vaccines are thus efficient tools to reduce disparities in wealth and inequities in health.
    1. IntroductionThe WHO Regional Office for Europe developed the Guide to tailoring immunization programmes (TIP), offering countries a process through which to diagnose barriers and motivators to vaccination in susceptible low vaccination coverage and design tailored interventions. A review of TIP implementation was conducted in the European Region.Material and methodsThe review was conducted during June to December 2016 by an external review committee and was based on visits in Bulgaria, Lithuania, Sweden and the United Kingdom that had conducted a TIP project; review of national and regional TIP documents and an online survey of the Member States in the WHO European Region that had not conducted a TIP project. A review committee workshop was held to formulate conclusions and recommendations.ResultsThe review found the most commonly cited strengths of the TIP approach to be the social science research as well as the interdisciplinary approach and community engagement, enhancing the ability of programmes to “listen” and learn, to gain an understanding of community and individual perspectives. National immunization managers in the Region are generally aware that TIP exists and that there is strong demand for the type of research it addresses. Further work is needed to assist countries move towards implementable strategies based on the TIP findings, supported by an emphasis on enhanced local ownership; integrated diagnostic and intervention design; and follow-up meetings, advocacy and incentives for decision-makers to implement and invest in strategies.ConclusionsUnderstanding the perspectives of susceptible and low-coverage populations is crucial to improving immunization programmes. TIP provides a framework that facilitated this in four countries. In the future, the purpose of TIP should go beyond identification of susceptible groups and diagnosis of challenges and ensure a stronger focus on the design of strategies and appropriate and effective interventions to ensure long-term change.
    1. Widely circulating coronavirus variants and persistent hesitancy about vaccines will keep the goal out of reach. The virus is here to stay, but vaccinating the most vulnerable may be enough to restore normalcy.
    1. COVID-19 has brought an epidemic of information which has produced detrimental mental health effects for young people. This systematic review protocol outlines the approach to investigating the available literature which assesses the relationship between COVID-19 related news and mental health outcomes in young people.
    1. The European Medicines Agency (EMA) has concluded that there is a possible link between rare but severe cases of blood clots (VITT) and the COVID-19 vaccine from Johnson & Johnson. As the COVID-19 epidemic in Denmark is currently under control, and the vaccination rollout is progressing satisfactorily with other available vaccines, the Danish Health Authority has decided to continue the national vaccination campaign without the COVID-19 vaccine from Johnson & Johnson.
    1. If you keep calm, put things in context and remain curious, you stand a much better chance of protecting yourself during the Covid-19 pandemic and avoiding feeling overwhelmed by scary statistics
    1. Coronavirus cases are surging in many countries, with the highest number of new cases now being reported in Asia. India alone reported 161,736 new cases on 12 April. In the Indian city of Surat, parts of gas furnaces used for cremations melted after being used non-stop. Meanwhile, millions have been gathering for festivals across the country.
    1. India, one of the world’s biggest suppliers of vaccines, is facing a COVID-19 vaccine crunch, partly due to an explosion of cases linked to new variants. This spells trouble for many countries relying on Indian-made vaccines supplied through the COVAX initiative for equitable access to vaccines, led by bodies including the World Health Organization.
    1. At least 97% of the funding for the development of the Oxford/AstraZeneca Covid-19 vaccine has been identified as coming from taxpayers or charitable trusts, according to the first attempt to reconstruct who paid for the decades of research that led to the lifesaving formulation.
    1. Taking stock after a year, what did the behavioural sciences get right? What went wrong?Did we manage to adapt as a research community in our scientific practice, our discourse, our tools, and in our research?
    1. It is now 13 months since this piece on "reconfiguring behavioural science" for rapid responding in the pandemic crisis.What have we learned? What did the behavioural sciences get right? What went wrong?Over the coming 10 days, we propose taking stock, and taking a step back both to revisit what we then hoped might change, but also what happened (for better or for worse) that completely escaped our radar at the time.To this end, we will launch a series of posts, sequentially starting thematic threads on key issues for a focussed discussion over the next 10 days.Please contribute, and please add any topics we might have missed by replying to this initial post- either here, if you are a member of this forum, or here if you are not.We will make sure discussion is consolidated!
    1. We use data on police-involved deaths to estimate how the risk of being killed by police use of force in the United States varies across social groups. We estimate the lifetime and age-specific risks of being killed by police by race and sex. We also provide estimates of the proportion of all deaths accounted for by police use of force. We find that African American men and women, American Indian/Alaska Native men and women, and Latino men face higher lifetime risk of being killed by police than do their white peers. We find that Latina women and Asian/Pacific Islander men and women face lower risk of being killed by police than do their white peers. Risk is highest for black men, who (at current levels of risk) face about a 1 in 1,000 chance of being killed by police over the life course. The average lifetime odds of being killed by police are about 1 in 2,000 for men and about 1 in 33,000 for women. Risk peaks between the ages of 20 y and 35 y for all groups. For young men of color, police use of force is among the leading causes of death.

    1. With vaccination programmes underway across the globe, attention is turning to the longer-term impact of COVID-19 and in particular the condition termed 'long Covid'. Very little is known about the condition at the moment, despite some studies estimating that 1 in 20 are affected. Large-scale research projects and population studies are now looking at the reported symptoms to understand what long Covid is, why some people are affected for months, and how we can treat it. Join Professor Brian Cox as he talks to scientists working at the forefront of research into long Covid, and campaigners with personal experience of the devastating effect it can have on lives. This event is part of a series of Royal Society events discussing the scientific response to the COVID-19 pandemic. Catch up with the first event on the Royal Society’s YouTube channel.
    1. It’s hard to convey the full depth and range of the trauma, the chaos and the indignity that people are being subjected to. Meanwhile, Modi and his allies are telling us not to complain
    1. Many scientists experience a practice-preference gap about peer review. Single-blind review---where authors' identities are revealed to reviewers---is often used for evaluation. Yet, double-blind review---where authors' identities are concealed---is seen as more fair. To understand this gap, we compared both systems in a high-stakes field study: submissions to the Society for Judgment and Decision Making’s annual conference, the leading international conference on this topic. Each submission received both review types. Reviewers were randomly assigned to the review system and submissions. Selected conference talks were evaluated for quality, popularity, and subsequent publication status. We assessed the two systems on reliability, bias, and validity. On reliability, while both systems had moderate reliability, agreement was higher on what constituted a poor submission than a strong one (Anna Karenina Principle). On bias, double-blind reviews showed a slight bias against submission by women (Matilda Effect), while single-blind reviews showed a preference for submissions with senior co-authors (Matthew Effect). On validity, neither system predicted talk quality or popularity, but both predicted publication status. Author characteristics did not consistently predict outcomes. Thus, we suggest the costs of single-blind review do not outweigh its benefits. Yet, double-blind review is also not a perfect solution. We propose an equitable approach for selecting scientific work may be an informed lottery: use double-blind review to identify submissions of merit, then randomly choose from this set.
    1. Background: The pace at which the present pandemic and future public health crises involving viral infections are eradicated heavily depends on the availability and routine implementation of vaccines. This process is further affected by a willingness to vaccinate, embedded in the phenomenon of vaccine hesitancy. The World Health Organization has listed vaccine hesitancy among the greatest threats to global health, calling for research to identify the factors associated with this phenomenon. Methods: The present study seeks to investigate the psychological, contextual, and sociodemographic factors associated with vaccination hesitancy in a large sample of the adult population. 4571 Norwegian adults were recruited through an online survey between January 23 to February 2, 2021. Subgroup analyses and multiple logistic regression was utilized to identify the covariates of vaccine hesitancy. Results: Several subgroups hesitant toward vaccination were identified, including males, rural residents, and parents with children below 18 years of age. No differences were found between natives and non-natives, across education or age groups. Individuals preferring unmonitored media platforms (e.g., information from peers, social media, online forums, and blogs) more frequently reported hesitance towards vaccination than those relying on information obtainment from source-verified platforms. Perceived risk of vaccination, belief in the superiority of natural immunity, fear concerning significant others being infected by the virus, and trust in health officials’ dissemination of vaccine-related information were identified as key variables related to vaccine hesitancy. Conclusions: Given the heterogeneous range of variables associated with vaccine hesitancy, additional strategies to eradicate vaccination fears are called for aside from campaigns targeting the spread of false information. Responding to affective reactions in addition to involving other community leaders besides government and health officials present promising approaches that may aid in combating vaccination hesitation.
    1. Purpose: This study explored predictors of COVID-19-related stress and wellbeing of Scottish adolescents during the COVID-19 lockdown to identify potentially malleable risk and protective factors. Methods: 5,548 participants were surveyed regarding stress, loneliness, wellbeing, schoolwork, support from school, and interaction with friends and family. Multiple linear regressions within a structural equation modelling framework were fit to predict COVID-19-related stress and wellbeing during the UK’s first lockdown. Results: Loneliness, variables related to the ability to continue with schoolwork, and perceived support from school were important predictors of greater COVID-19-related stress and wellbeing during the first lockdown. Female adolescents were also more likely to show higher stress and poorer wellbeing. Conclusions: Facilitating meaningful social interaction and ensuring the ability to continue with schoolwork, and providing social support from school should be priority strategies to help protect the mental health and wellbeing of secondary school students during lockdowns and other disruptions to school attendance.
    1. Objective: The COVID-19 pandemic has worsened college students’ mental health while simultaneously creating new barriers to traditional in-person care. Teletherapy and online self-guided mental health supports are two potential avenues for addressing unmet mental health needs when face-to-face services are less accessible, but little is known about factors that shape interest in these supports. Participants: 1,224 U.S. undergraduate students (mean age=20.7; 72.5% female; 40.0% White) participated. Methods: Students completed an online questionnaire assessing interest in teletherapy and self-guided supports. Predictors included age, sex, ethnicity, sexual minority status, and anxiety and depression symptomatology. Results: Interest rates were 20% and 25% for at-cost supports and 70% and 72% for free supports. Older age, higher anxiety symptomatology, and identifying as Asian significantly predicted greater interest levels. Conclusions: Results may inform universities’ efforts to optimize students’ engagement with nontraditional, digital mental health supports, including teletherapy and self-guided programs.
    1. Prior work has suggested that existential threats in the form of terror attacks may shift liberals’ reliance on moral foundations to more resemble those of conservatives. We therefore hypothesized that endorsement of these moral foundations would have increased when the COVID-19 epidemic became a salient threat. To examine this hypothesis we conducted a longitudinal study with 237 American participants across the liberal-conservative spectrum, in which their endorsement of various moral foundations were measured before and after the advent of the pandemic. We did not find evidence of any systematic change in the endorsement of any moral foundation, neither in general nor specifically among liberals or specifically among those who perceived the greatest threat from COVID-19. We conclude that the threat from the pandemic does not seem to have had any substantial effect on the moral foundations that people rely on. This finding is consistent with other longitudinal studies of the effect of the COVID-19 pandemic on measures related to conservatism.
    1. Moral judgments have a very prominent social nature, and in everyday life, they are continually shaped by discussions with others. Psychological investigations of these judgments, however, have rarely addressed the impact of face-to-face interaction. To examine the role of social deliberation within small groups on moral judgments, we had groups of 4 to 5 participants judge moral dilemmas first individually and privately, then collectively and interactively, and finally individually a second time. We employed both real-life and sacrificial moral dilemmas in which the character’s action or inaction violated a moral principle to benefit the greatest number of people. Participants decided if these utilitarian decisions were morally acceptable or not. We found that collectives were more utilitarian than the statistical aggregate of their members compared to both first and second individual judgments. This supports the hypothesis that deliberation and consensus within a group transiently reduced the emotional burden of norm violation and indicates normative conformity in moral judgments.
    1. In recent years, vaccination rates in the Netherlands have declined slightly, but steadily. The Dutch National Institute for Public Health and the Environment (RIVM) commissioned a Committee for Vaccine Willingness (VWC) to study the societal context of the decline. One of the societal contexts is the Internet, where audiences discuss vaccination and refer to sources of health-related information of varying quality.Working for the VWC, we have explored the Dutch vaccination debate on Twitter in order to: (1) identify online communities in the vaccination debate, (2) identify vaccine-related narratives; and (3) understand how the online communities interact with each other. We identified seven different communities, including (public) health professionals, writers and journalists, anti-establishment, and international vaccination advocates.The debate is spearheaded by the writers & journalists community, while the health- and anti-establishment communities try to influence it. The health community circulates facts, figures and scientific studies, while negative messages about vaccination – either from a homeopathy or conspiracy perspective – are most prevalent in the anti-establishment. The facts and figures shared by the health community hardly reach other communities, whereas the myths introduced by the anti-establishment do spill over to other communities. Our study provides further evidence that negative perceptions about vaccination might be rooted in a wider sentiment of distrust of traditional institutions.We argue that Dutch health organizations should try to address questions, doubts, and worries among the general audience more actively, and present scientific information in a simpler and more attractive way.
    1. Vaccination is a crucial tool for preventing and controlling disease, but its use has been plagued by controversies worldwide [1–6]. In this article, I look at the controversy surrounding the immunization program against polio in Nigeria, in which three states in northern Nigeria in 2003 boycotted the polio immunization campaign. I discuss the problems caused by the boycott, its implications, and how it was resolved. Finally, I make recommendations for the future to prevent a similar situation from arising.

Most academic studies of vaccine resistance online use quantitative methods to describe misinformation on vaccine-skeptical websites. Findings from these studies are useful for categorizing the generic features of these websites, but they do not provide insights into why these websites successfully persuade their viewers. To date, there have been few attempts to understand, qualitatively, the persuasive features of provaccine or vaccine-skeptical websites.Objective: The purpose of this research was to examine the persuasive features of provaccine and vaccine-skeptical websites. The qualitative analysis was conducted to generate hypotheses concerning what features of these websites are persuasive to people seeking information about vaccination and vaccine-related practices.Methods: This study employed a fully qualitative case study methodology that used the anthropological method of thick description to detail and carefully review the rhetorical features of 1 provaccine government website, 1 provaccine hospital website, 1 vaccine-skeptical information website focused on general vaccine safety, and 1 vaccine-skeptical website focused on a specific vaccine. The data gathered were organized into 5 domains: website ownership, visual and textual content, user experience, hyperlinking, and social interactivity.Results: The study found that the 2 provaccine websites analyzed functioned as encyclopedias of vaccine information. Both of the websites had relatively small digital ecologies because they only linked to government websites or websites that endorsed vaccination and evidence-based medicine. Neither of these websites offered visitors interactive features or made extensive use of the affordances of Web 2.0. The study also found that the 2 vaccine-skeptical websites had larger digital ecologies because they linked to a variety of vaccine-related websites, including government websites. They leveraged the affordances of Web 2.0 with their interactive features and digital media.Conclusions: By employing a rhetorical framework, this study found that the provaccine websites analyzed concentrate on the accurate transmission of evidence-based scientific research about vaccines and government-endorsed vaccination-related practices, whereas the vaccine-skeptical websites focus on creating communities of people affected by vaccines and vaccine-related practices. From this personal framework, these websites then challenge the information presented in scientific literature and government documents. At the same time, the vaccine-skeptical websites in this study are repositories of vaccine information and vaccination-related resources. Future studies on vaccination and the Internet should take into consideration the rhetorical features of provaccine and vaccine-skeptical websites and further investigate the influence of Web 2.0 community-building features on people seeking information about vaccine-related practices.
    1. Objective. During the second half of the 1990s and the first years of the 2000s a declining coverage for MMR vaccination in two-year-olds was observed in Sweden. The aim was to assess reasons for postponement or non-vaccination. Design. A telephone survey using a structured questionnaire on parents’ attitudes regarding their choice to postpone or abstain from vaccinating their child. Setting. The County of Östergötland in Sweden. Subjects. A total of 203 parents of children who had no registered date for MMR vaccination at a Child Health Centre. Main outcome measures. Parental reasons for non-vaccination. Results. In all, 26 of the 203 children had received MMR vaccination but this had not been registered. Of those not vaccinated, 40% of the parents had decided to abstain and 60% to postpone vaccination. Fear of side effects was the most common reason for non-vaccination in both groups. The main source of information was the media followed by the Child Health Centre. Parents with a single child more often postponed vaccination and those who abstained were more likely to have had a discussion with a doctor or nurse about MMR vaccine. Conclusion. Postponers and abstainers may have different reasons for their decision. The role of well-trained healthcare staff in giving advice and an opportunity to discuss MMR vaccination with concerned parents is very important.
    1. Context Individuals searching the Internet for vaccine information may find antivaccination Web sites. Few published studies have systematically evaluated these sites.Objectives To examine antivaccination Web site attributes and to delineate the specific claims and concerns expressed by antivaccination groups.Design and Setting In late 2000, using a metasearch program that incorporates 10 other search engines, we reviewed and analyzed 772 links to find 12 Web sites that promulgated antivaccination information. Analyzing links from these 12 sites yielded another 10 sites, producing a total of 22 sites for study. Using a standardized form, 2 authors (R.M.W., L.K.S.) systematically evaluated these sites based on specific content and design attributes.Main Outcome Measures Presence or absence of 11 Web site content attributes (antivaccination claims) and 10 Web site design attributes.Results The most commonly found content claims were that vaccines cause idiopathic illness (100% of sites), vaccines erode immunity (95%), adverse vaccine reactions are underreported (95%), and vaccination policy is motivated by profit (91%). The most common design attributes were the presence of links to other antivaccination sites (100%of sites), information for legally avoiding immunizations (64%), and the use of emotionally charged stories of children who had allegedly been killed or harmed by vaccines (55%).Conclusion Antivaccination Web sites express a range of concerns related to vaccine safety and varying levels of distrust in medicine. The sites rely heavily on emotional appeal to convey their message.
    1. The current research tested if explicit anti‐conspiracy arguments could be an effective method of addressing the potentially harmful effects of anti‐vaccine conspiracy theories. In two studies, participants were presented with anti‐conspiracy arguments either before, or after reading arguments in favor of popular conspiracy theories concerning vaccination. In both studies, anti‐conspiracy arguments increased intentions to vaccinate a fictional child but only when presented prior to conspiracy theories. This effect was mediated by belief in anti‐vaccine conspiracy theories and the perception that vaccines are dangerous. These findings suggest that people can be inoculated against the potentially harmful effects of anti‐vaccine conspiracy theories, but that once they are established, the conspiracy theories may be difficult to correct.
    1. This large-scale Internet-experiment tests whether vaccine-critical pages raise perceptions of the riskiness of vaccinations and alter vaccination intentions. We manipulated the information environment (vaccine-critical website, control, both) and the focus of search (on vaccination risks, omission risks, no focus). Our analyses reveal that accessing vaccine-critical websites for five to 10 minutes increases the perception of risk of vaccinating and decreases the perception of risk of omitting vaccinations as well as the intentions to vaccinate. In line with the ‘risk-as-feelings’ approach, the affect elicited by the vaccine-critical websites was positively related to changes in risk perception.
    1. Objective: Vaccine hesitancy has been identified as one of the major contributors to child under-vaccination. Research indicates that some hesitant parents’ mistrust extends to specific conspiracy ideation, but research on vaccine conspiracy beliefs is still scarce. Our objective was to explore factors contributing to parental vaccine conspiracy beliefs and actual vaccine uptake in children.Design: A cross-sectional correlational design with a non-probabilistic sample of 823 volunteer participants surveyed online.Main outcome measures: We focussed on the contributions of the analytically rational and experientially intuitive thinking styles, as well as measures of emotional functioning, namely optimism and emotions towards vaccination, to vaccine conspiracy beliefs and vaccine uptake as outcomes.Results: The obtained results showed that greater vaccine conspiracy beliefs were associated with stronger unpleasant emotions towards vaccination and greater experientially intuitive thinking, as well as lower levels of education. Furthermore, unpleasant emotions towards vaccination and intuitive thinking were associated with vaccine refusal.Conclusion: These findings confirm the primary importance of emotions, along with the propensity towards intuitive thinking, in the context of vaccine conspiracy beliefs and refusal, supporting the notion that parents’ avoidance is guided by their affect. These results have direct implications for addressing vaccine hesitancy within public campaigns and policies.
    1. With little or no evidence-based information to back up claims of vaccine danger, anti-vaccine activists have relied on the power of storytelling to infect an entire generation of parents with fear of and doubt about vaccines. These parent accounts of perceived vaccine injury, coupled with Andrew Wakefield’s fraudulent research study linking the MMR vaccine to autism, created a substantial amount of vaccine hesitancy in new parents, which manifests in both vaccine refusal and the adoption of delayed vaccine schedules. The tools used by the medical and public health communities to counteract the anti-vaccine movement include statistics, research, and other evidence-based information, often delivered verbally or in the form of the CDC’s Vaccine Information Statements. This approach may not be effective enough on its own to convince vaccine-hesitant parents that vaccines are safe, effective, and crucial to their children’s health. Utilizing some of the storytelling strategies used by the anti-vaccine movement, in addition to evidence-based vaccine information, could potentially offer providers, public health officials, and pro-vaccine parents an opportunity to mount a much stronger defense against anti-vaccine messaging.
    1. AbstractIn a scholarly analysis of widely held misconceptions, Gilovich provides a classification scheme of common flaws in reasoning seen in contemporary society. He broadly categorizes these flaws as having cognitive determinants or in having motivational and social determinants. In this survey, the authors examine the various claims against routine childhood and adult vaccines as made by the more public and more organized entities of the anti-vaccine movement as well as those made apparent by surveys of parents and other groups of individuals. The claims illustrate the breadth of reasoning flaws while providing a basis for anticipating and correcting them.
    1. Objective:To evaluate whether the MMR vaccine increases the risk for autism in children, subgroups of children, or time periods after vaccination.Design:Nationwide cohort study.Setting:Denmark.Participants:657 461 children born in Denmark from 1999 through 31 December 2010, with follow-up from 1 year of age and through 31 August 2013.Measurements:Danish population registries were used to link information on MMR vaccination, autism diagnoses, other childhood vaccines, sibling history of autism, and autism risk factors to children in the cohort. Survival analysis of the time to autism diagnosis with Cox proportional hazards regression was used to estimate hazard ratios of autism according to MMR vaccination status, with adjustment for age, birth year, sex, other childhood vaccines, sibling history of autism, and autism risk factors (based on a disease risk score).Results:During 5 025 754 person-years of follow-up, 6517 children were diagnosed with autism (incidence rate, 129.7 per 100 000 person-years). Comparing MMR-vaccinated with MMR-unvaccinated children yielded a fully adjusted autism hazard ratio of 0.93 (95% CI, 0.85 to 1.02). Similarly, no increased risk for autism after MMR vaccination was consistently observed in subgroups of children defined according to sibling history of autism, autism risk factors (based on a disease risk score) or other childhood vaccinations, or during specified time periods after vaccination.Limitation:No individual medical charts were reviewed.Conclusion:The study strongly supports that MMR vaccination does not increase the risk for autism, does not trigger autism in susceptible children, and is not associated with clustering of autism cases after vaccination. It adds to previous studies through significant additional statistical power and by addressing hypotheses of susceptible subgroups and clustering of cases.
    1. weets across user types. We conducted a content analysis of a Twitter hashtag associated with Russian troll activity.Results. Compared with average users, Russian trolls (χ2(1) = 102.0; P < .001), sophisticated bots (χ2(1) = 28.6; P < .001), and “content polluters” (χ2(1) = 7.0; P < .001) tweeted about vaccination at higher rates. Whereas content polluters posted more antivaccine content (χ2(1) = 11.18; P < .001), Russian trolls amplified both sides. Unidentifiable accounts were more polarized (χ2(1) = 12.1; P < .001) and antivaccine (χ2(1) = 35.9; P < .001). Analysis of the Russian troll hashtag showed that its messages were more political and divisive.Conclusions. Whereas bots that spread malware and unsolicited content disseminated antivaccine messages, Russian trolls promoted discord. Accounts masquerading as legitimate users create false equivalency, eroding public consensus on vaccination.Public Health Implications. Directly confronting vaccine skeptics enables bots to legitimize the vaccine debate. More research is needed to determine how best to combat bot-driven content.
    1. Objectives. To understand how Twitter accounts operated by the Russian Internet Research Agency (IRA) discussed vaccines to increase the credibility of their manufactured personas.Methods. We analyzed 2.82 million tweets published by 2689 IRA accounts between 2015 and 2017. Combining unsupervised machine learning and network analysis to identify “thematic personas” (i.e., accounts that consistently share the same topics), we analyzed the ways in which each discussed vaccines.Results. We found differences in volume and valence of vaccine-related tweets among 9 thematic personas. Pro-Trump personas were more likely to express antivaccine sentiment. Anti-Trump personas expressed support for vaccination. Others offered a balanced valence, talked about vaccines neutrally, or did not tweet about vaccines.Conclusions. IRA-operated accounts discussed vaccines in manners consistent with fabricated US identities.Public Health Implications. IRA accounts discussed vaccines online in ways that evoked political identities. This could exacerbate recently emerging partisan gaps relating to vaccine misinformation, as differently valenced messages were targeted at different segments of the US public. These sophisticated targeting efforts, if repeated and increased in reach, could reduce vaccination rates and magnify health disparities.
    1. BNT162b2 mRNA and ChAdOx1 nCOV-19 adenoviral vector vaccines have been rapidly rolled out in the UK from December, 2020. We aimed to determine the factors associated with vaccine coverage for both vaccines and documented the vaccine effectiveness of the BNT162b2 mRNA vaccine in a cohort of health-care workers undergoing regular asymptomatic testing.
    1. The EU is yet to decide whether to launch legal action against AstraZeneca over the company’s failure to deliver the contracted doses to the bloc, the European commission president, Ursula von der Leyen, has said. She told a news conference: Where AstraZeneca is concerned no decision have been taken so far so we have to wait for that. AstraZeneca delivered less than 30m of the expected 120m doses to EU member states in the first quarter of this year, and refused to redirect vaccines produced in the UK to make up for the losses. The commission sent a letter to the company on 19 March, described as a “a notice for dispute settlement”.
    1. All three Covid-19 vaccines available in America are remarkably effective. As the Centers for Disease Control and Prevention put it, “The best Covid-19 vaccine is the first one that is available to you.” Most people aren’t even in a position to choose which one they get. “It’s like the sorting hat in ‘Harry Potter,’” said Mr. Thomas.
    1. External enforcement policies aimed to reduce violations differ on two key components: the probability of inspection and the severity of punishments. Different lines of research offer competing predictions regarding the relative importance of each component. In three incentive compatible studies, students and Prolific crowdsourcing participants (Ntotal=430) repeatedly faced temptations to commit violations under two enforcement policies. Controlling for expected value, the results indicated that a policy combining High probability of Inspection with Low Severity of fine (HILS) was more effective than a policy combining Low probability of Inspection with High Severity of fine (LIHS). Consistent with the prediction of Decisions from Experience research, this finding held even when the severity of the fine was stated in advance to boost deterrence. In addition, the advantage of HILS over LIHS was greater as participants’ baseline rate of violation (without enforcement) was higher, implying that HILS is more effective among frequent offenders.
    1. One issue we forsaw becoming a concern (though personally, I foresaw nothing like the tsunami that ensued) was the potential problem of disinformation and bad faith actors.We thought at the time that behavioural scientists should distill research on the spread of misinformation and how best to guard against disinformation and disruption into usable guidelines that can be made available to all members of the behavioural science community.How did we, as a community, do on these issues? What did we get right, what did we get wrong? What scope for improvement is there? What else have we learned?

    1. WASHINGTON—In pausing the use of Johnson & Johnson COVID-19 vaccine Tuesday to investigate reports of six cases of dangerous blood clots occurring among the roughly 6.8 million people who have received it, U.S. medical authorities in part wanted to maintain confidence in the safety of the vaccine supply. Dr. Anthony Fauci, the U.S. government’s top infectious disease official, said it was “testimony to how seriously we take safety.”
    1. Experts say we should investigate “breakthrough infections” to look out for variants and understand who’s vulnerable. In many cases, that’s not happening. Crucial pieces of the puzzle are being tossed in the trash.
    1. ● Prior to the pandemic there was a 4-5% annual rise in the number of mental health related GP referrals in Scotland. ● There was a 27% drop in referrals in 2020, affecting 43,522 patients. ● Previous pandemic related research shows that restrictions imposed to curb infections led to higher incidence of mental health problems and therefore it is likely that the true figure of those in need of referral far exceeds this figure. ● If the mental health services are restored to their pre-pandemic levels, the tens of thousands of patients who have not been referred yet, will face years on waiting lists before specialist help can be provided. ● There is an urgent need to re-evaluate COVID imposed restrictions on the operations of NHS services to address the challenges.
    1. INTRODUCTIONAs the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic continues, the deployment of safe and effective vaccines presents a key intervention for mitigating disease severity and spread. Numerous logistical challenges and shortages have emerged alongside the international distribution of approved vaccines. In response, several countries have chosen to delay the second dose in an effort to increase the number of individuals receiving at least one dose. A key question then becomes how the timing of delivery of the second dose will affect future epidemiological and evolutionary outcomes.RATIONALEWe build on an existing immuno-epidemiological framework that assumes that, without vaccination, individual immunity after recovery from primary infection may eventually wane, leading to (a potentially reduced) susceptibility to secondary infections. To explore epidemiological outcomes, we extend the model to incorporate two vaccinated classes, corresponding to individuals who have received either one dose or two doses of a SARS-CoV-2 vaccine. As with natural immunity, we allow for one- or two-dose vaccinal immunity to wane, and we consider a continuous spectrum for the interdose period between vaccines. To reflect the increase in available doses resulting from a delayed second dose, we model the rate of administration of the first dose as an increasing function of the interdose period. We then consider evolutionary outcomes by coupling this framework to a simple phylodynamic model for potential viral adaptation under different evolutionary scenarios, each with its own assumptions regarding viral abundance and within-host selection for the different partially susceptible classes.RESULTSWe find that delaying second vaccine doses reduces COVID-19 infections in the short term by increasing the proportion of immune individuals. In the longer term, however, both the infection burden and the relative potential for viral adaptation are highly dependent on the robustness of natural or vaccinal immune responses. Notably, we find that even if immunity conferred by a single vaccine dose is poor, starting with a one-dose policy early on to increase the number of individuals immunized and then switching to the manufacturer-recommended two-dose regime as vaccine capacity increases can mitigate potential negative longer-term epidemiological and evolutionary outcomes. This mitigation can also be achieved by ramping up overall vaccination rates as availability improves.CONCLUSIONThe deployment of SARS-CoV-2 vaccines will strongly shape postpandemic epidemiological trajectories and characteristics of accumulated population immunity. Our models show that the combination of different vaccine dosing regimes and variations in the robustness of natural and vaccinal immunity may result in a wide range of potential epidemiological and evolutionary outcomes in the medium term. It is therefore imperative to determine the strength and duration of clinical protection and transmission-blocking immunity through careful clinical evaluations in order to enforce sound public policies. In places where vaccine deployment is delayed and vaccination rates are low, our results stress the subsequent negative epidemiological and evolutionary impacts that may emerge. Particularly because these consequences (for example, the evolution of new variants) could emerge as global problems, there is an urgent need for global equity in vaccine distribution and deployment.
    1. One shot of the Oxford/AstraZeneca or Pfizer/BioNTech vaccine reduces coronavirus infections by nearly two-thirds and protects older and more vulnerable people as much as younger, healthy individuals, a study has found.The results from Oxford University and the Office for National Statistics are a welcome boost to the vaccination programme and the first to show the impact on new infections and immune responses in a large group of adults in the general population.By driving down rates of infection the vaccines will not only prevent hospitalisations and deaths but help break chains of transmission and so reduce the risk of a damaging resurgence of disease as the UK reopens.
    1. For decades, Africa has imported 99% of its vaccines. Now the continent’s leaders want to bring manufacturing home.
    1. The global spread of the novel coronavirus is affected by the spread of related mis-information — the so-called COVID-19 Infodemic — that makes populations morevulnerable to the disease through resistance to mitigation efforts. Here we analyzethe prevalence and diffusion of links to low-credibility content about the pandemicacross two major social media platforms, Twitter and Facebook. We characterizecross-platform similarities and differences in popular sources, diffusion patterns, influ-encers, coordination, and automation. Comparing the two platforms, we find diver-gence among the prevalence of popular low-credibility sources and suspicious videos.A minority of accounts and pages exert a strong influence on each platform. Thesemisinformation “superspreaders” are often associated with the low-credibility sourcesand tend to be verified by the platforms. On both platforms, there is evidence of co-ordinated sharing of Infodemic content. The overt nature of this manipulation pointsto the need for societal-level rather than in-house mitigation strategies. However, wehighlight limits imposed by inconsistent data-access policies on our capability to studyharmful manipulations of information ecosystems.
    1. Heneghan and colleagues' systematic review, funded by WHO, published in March, 2021, as a preprint, states: “The lack of recoverable viral culture samples of SARS-CoV-2 prevents firm conclusions to be drawn about airborne transmission”.1Heneghan C Spencer E Brassey J et al.SARS-CoV-2 and the role of airborne transmission: a systematic review.F1000Research. 2021; (published online March 24.)

    2. Selectively publishing results that support the tested hypotheses (“positive” results) distorts the available evidence for scientific claims. For the past decade, psychological scientists have been increasingly concerned about the degree of such distortion in their literature. A new publication format has been developed to prevent selective reporting: In Registered Reports (RRs), peer review and the decision to publish take place before results are known. We compared the results in published RRs (N = 71 as of November 2018) with a random sample of hypothesis-testing studies from the standard literature (N = 152) in psychology. Analyzing the first hypothesis of each article, we found 96% positive results in standard reports but only 44% positive results in RRs. We discuss possible explanations for this large difference and suggest that a plausible factor is the reduction of publication bias and/or Type I error inflation in the RR literature.
    1. Hello. This is Eric Topol on Medscape, and with me is my co-host Abraham Verghese. This is a really special edition of our podcast, Medicine and the Machine, because we have a phenom here, truly: Professor Devi Sridhar, the professor of Global Health at the University of Edinburgh, who has been a guiding light for the pandemic not only in Scotland or the UK, but for the world. It's actually kind of amazing given her background, her age, and everything else. Devi, welcome.
    1. This paper focuses on recent developments in UK health research policy, which place new pressures on researchers to address issues of accountability and impact through the implementation of patient and public involvement (PPI). We draw on an in-depth interview study with 20 professional researchers, and we analyse their experiences of competing for research funding, focusing on PPI as a process of professional research governance. We unearth dominant professional narratives of scepticism and alternative identifications in their enactment of PPI policy. We argue that such narratives and identifications evidence a resistance to ways in which patient involvement has been institutionalised and to the resulting subject-positions researchers are summoned to take up. We show that the new subjectivities emerging in this landscape of research governance as increasingly disempowered, contradictory and fraught with unresolved tensions over the ethical dimensions of the researchers’ own professional identities.
    1. As COVID-19 continues to strain public health systems and vaccination programmes race against new variants that might be more transmissible or capable of evading immune responses, the urgent need for simple, accessible, and frequent testing remains. Inexpensive, scalable, and sustainable strategies that allow easily repeatable testing over time need to be made widely available. This is possible by testing saliva.
    1. The European Commission and Austria are announcing today the conclusion of agreements for the delivery of COVID-19 vaccines for the Western Balkans. The 651,000 BioNTech/Pfizer doses are funded by the European Commission and will be shared with the facilitation of Austria. The first delivery to all the partners in the region is due in May, with regular tranches to continue until August.
    1. More people were diagnosed with Covid-19 during the past seven days than any other week since the start of the pandemic -- topping 5.2 million globally -- with the worst outbreaks accelerating in many countries that are ill-equipped to deal with them.
    1. Imagine two scientists, Kotrina and Amber, who have just obtained their PhDs and are entering the job market.Kotrina has four empirical papers. She is first author on two, including a publication in a prominent psychology journal, Journal of Experimental Psychology: General. Kotrina has 75 citations, with two papers cited 25 times each—not bad for a newly-minted PhD. She has also mentored five undergraduate students on their honors theses and has obtained a modest research grant.Amber has seven empirical papers. She is first author on five, including three publications in prominent journals, Psychological Science, Journal of Experimental Psychology: General, and PNAS. Amber has over 200 citations, with four papers cited more than 40 times each—impressive for a newly-minted PhD. She has also mentored five undergraduate students on their honors theses and has obtained a major research grant.Suppose you were a member of a search committee, and Kotrina and Amber were in the running for your department's final interview spot. Who would you choose?
    1. The basic reproductive number (R0) is a function of contact rates among individuals, transmission probability, and duration of infectiousness. We sought to determine the association between population density and R0 of SARS-CoV-2 across U.S. counties. We conducted a cross-sectional analysis using linear mixed models with random intercept and fixed slopes to assess the association of population density and R0, and controlled for state-level effects using random intercepts. We also assessed whether the association was differential across county-level main mode of transportation percentage as a proxy for transportation accessibility, and adjusted for median household income. The median R0 among the United States counties was 1.66 (IQR: 1.35–2.11). A population density threshold of 22 people/km2 was needed to sustain an outbreak. Counties with greater population density have greater rates of transmission of SARS-CoV-2, likely due to increased contact rates in areas with greater density. An increase in one unit of log population density increased R0 by 0.16 (95% CI: 0.13 to 0.19). This association remained when adjusted for main mode of transportation and household income. The effect of population density on R0 was not modified by transportation mode. Our findings suggest that dense areas increase contact rates necessary for disease transmission. SARS-CoV-2 R0 estimates need to consider this geographic variability for proper planning and resource allocation, particularly as epidemics newly emerge and old outbreaks resurge.
    1. The UK government is facing legal action over a £102.6m (€119m; $143m) contract for FFP3 respirators to be worn by healthcare staff treating covid-19 patients, which was granted without competition last July.The claim is the latest by the Good Law Project to challenge the lawfulness of government action in procuring personal protective equipment (PPE) during the covid-19 pandemic.
    1. In humans, sleep regulation is tightly linked to social times that assign local time to events, such as school, work, or meals. The impact of these social times, collectively—social time pressure, on sleep has been studied epidemiologically via quantification of the discrepancy between sleep times on workdays and those on work-free days. This discrepancy is known as the social jetlag (SJL). COVID-19-mandated social restrictions (SR) constituted a global intervention by affecting social times worldwide. We launched a Global Chrono Corona Survey (GCCS) that queried sleep–wake times before and during SR (preSR and inSR). 11,431 adults from 40 countries responded between April 4 and May 6, 2020. The final sample consisted of 7517 respondents (68.2% females), who had been 32.7 ± 9.1 (mean ± sd) days under SR. SR led to robust changes: mid-sleep time on workdays and free days was delayed by 50 and 22 min, respectively; sleep duration increased on workdays by 26 min but shortened by 9 min on free days; SJL decreased by ~ 30 min. On workdays inSR, sleep–wake times in most people approached those of their preSR free days. Changes in sleep duration and SJL correlated with inSR-use of alarm clocks and were larger in young adults. The data indicate a massive sleep deficit under pre-pandemic social time pressure, provide insights to the actual sleep need of different age-groups and suggest that tolerable SJL is about 20 min. Relaxed social time pressure promotes more sleep, smaller SJL and reduced use of alarm clocks.
    1. CLAIM: A Stanford University study published on the National Institutes of Health website proves face masks are absolutely worthless against COVID-19.AP’S ASSESSMENT: False. This study is not affiliated with Stanford University, nor does the author work for the Veterans Affairs Palo Alto Health Care System as he claims. The study presents a hypothesis that includes false claims about the health effects of wearing masks. The U.S. Centers for Disease Control and Prevention continues to recommend wearing face coverings to reduce the spread of COVID-19, as research shows they can block the transmission of respiratory droplets, which spread the virus.THE FACTS: Websites and social media users ranging from political candidates to health influencers are falsely claiming a study published on a digital research repository came from Stanford University and proves face masks are ineffective.

    1. On 25 March 2021, The BMJ hosted a webinar on new variants. An expert panel discussed what these are, where they come from, and what they might do, as well as what we know about how particular variants influence transmission, severity, and immunity, and what this means for the future of the pandemic.

    1. BackgroundMany pregnant persons in the United States are receiving messenger RNA (mRNA) coronavirus disease 2019 (Covid-19) vaccines, but data are limited on their safety in pregnancy. MethodsFrom December 14, 2020, to February 28, 2021, we used data from the “v-safe after vaccination health checker” surveillance system, the v-safe pregnancy registry, and the Vaccine Adverse Event Reporting System (VAERS) to characterize the initial safety of mRNA Covid-19 vaccines in pregnant persons. ResultsA total of 35,691 v-safe participants 16 to 54 years of age identified as pregnant. Injection-site pain was reported more frequently among pregnant persons than among nonpregnant women, whereas headache, myalgia, chills, and fever were reported less frequently. Among 3958 participants enrolled in the v-safe pregnancy registry, 827 had a completed pregnancy, of which 115 (13.9%) resulted in a pregnancy loss and 712 (86.1%) resulted in a live birth (mostly among participants with vaccination in the third trimester). Adverse neonatal outcomes included preterm birth (in 9.4%) and small size for gestational age (in 3.2%); no neonatal deaths were reported. Although not directly comparable, calculated proportions of adverse pregnancy and neonatal outcomes in persons vaccinated against Covid-19 who had a completed pregnancy were similar to incidences reported in studies involving pregnant women that were conducted before the Covid-19 pandemic. Among 221 pregnancy-related adverse events reported to the VAERS, the most frequently reported event was spontaneous abortion (46 cases). ConclusionsPreliminary findings did not show obvious safety signals among pregnant persons who received mRNA Covid-19 vaccines. However, more longitudinal follow-up, including follow-up of large numbers of women vaccinated earlier in pregnancy, is necessary to inform maternal, pregnancy, and infant outcomes.
    1. Essential workers, often low-wage and compensated by the hour, are getting vaccinated at lower rates than other groups. Many attribute this reduced vaccine uptake to “vaccine hesitancy” due to false beliefs or even justified skepticism. But there is a systematic Catch-22 that has been created: At least 40% of people who get vaccinated experience flu-like symptoms one to two days after their injection, and anyone with these symptoms is not allowed to come to work.
    1. A history of the anti-vaccination movement, from its nineteenth-century antecedents to today's anti-vax activism, offering strategies for refuting its claims.
    1. Over the past decade, anti-vaccination rhetoric has become part of the mainstream discourse regarding the public health practice of childhood vaccination. These utilise social media to foster online spaces that strengthen and popularise anti-vaccination discourses. In this paper, we examine the characteristics of and the discourses present within six popular anti-vaccination Facebook pages. We examine these large-scale datasets using a range of methods, including social network analysis, gender prediction using historical census data, and generative statistical models for topic analysis (Latent Dirichlet allocation). We find that present-day discourses centre around moral outrage and structural oppression by institutional government and the media, suggesting a strong logic of ‘conspiracy-style’ beliefs and thinking. Furthermore, anti-vaccination pages on Facebook reflect a highly ‘feminised’ movement ‒ the vast majority of participants are women. Although anti-vaccination networks on Facebook are large and global in scope, the comment activity sub-networks appear to be ‘small world’. This suggests that social media may have a role in spreading anti-vaccination ideas and making the movement durable on a global scale.
    1. ObjectivesImmunization is considered one of the most successful and cost-effective public health interventions protecting communities from preventable infectious diseases. The Korean government set up a dedicated workforce for national immunization in 2003, and since then has made strides in improving vaccination coverage across the nation. However, some groups remain relatively vulnerable and require intervention, and it is necessary to address unmet needs to prevent outbreaks of communicable diseases. This study was conducted to characterize persistent challenges to vaccination.MethodsThe study adopted a qualitative method in accordance with the Consolidated Criteria for Reporting Qualitative Research checklist. Three focus group interviews were conducted with 15 professionals in charge of vaccination-related duties. The interviews were conducted according to a semi-structured guideline, and thematic analysis was carried out. Data saturation was confirmed when the researchers agreed that no more new codes could be found.ResultsA total of 4 main topics and 11 subtopics were introduced regarding barriers to vaccination. The main topics were vaccine hesitancy, personal circumstances, lack of information, and misclassification. Among them, vaccine hesitancy was confirmed to be the most significant factor impeding vaccination. It was also found that the factors hindering vaccination had changed over time and disproportionately affected certain groups.ConclusionsThe study identified ongoing unmet needs and barriers to vaccination despite the accomplishments of the National Immunization Program. The results have implications for establishing tailored interventions that target context- and group-specific barriers to improve timely and complete vaccination coverage.
    1. ObjectiveAlthough the benefits of vaccines are widely recognized by medical experts, public opinion about vaccination policies is mixed. We analyze public opinion about vaccination policies to assess whether Dunning-Kruger effects can help to explain anti-vaccination policy attitudes.RationalePeople low in autism awareness – that is, the knowledge of basic facts and dismissal of misinformation about autism – should be the most likely to think that they are better informed than medical experts about the causes of autism (a Dunning-Kruger effect). This “overconfidence” should be associated with decreased support for mandatory vaccination policies and skepticism about the role that medical professionals play in the policymaking process.MethodIn an original survey of U.S. adults (N = 1310), we modeled self-reported overconfidence as a function of responses to a knowledge test about the causes of autism, and the endorsement of misinformation about a link between vaccines and autism. We then modeled anti-vaccination policy support and attitudes toward the role that experts play in the policymaking process as a function of overconfidence and the autism awareness indicators while controlling for potential confounding factors.ResultsMore than a third of respondents in our sample thought that they knew as much or more than doctors (36%) and scientists (34%) about the causes of autism. Our analysis indicates that this overconfidence is highest among those with low levels of knowledge about the causes of autism and those with high levels of misinformation endorsement. Further, our results suggest that this overconfidence is associated with opposition to mandatory vaccination policy. Overconfidence is also associated with increased support for the role that non-experts (e.g., celebrities) play in the policymaking process.ConclusionDunning-Kruger effects can help to explain public opposition to vaccination policies and should be carefully considered in future research on anti-vaccine policy attitudes.
    1. BackgroundConspiracies about vaccination are prevalent. We assessed how the health information sources people rely upon and their political ideologies are associated with acceptance of vaccine conspiracies.MethodsOnline survey (N = 599) on Amazon’s Mechanical Turk crowdsource platform. Hypotheses were tested via structural equation modeling.ResultsAcceptance of vaccine conspiracy beliefs was associated positively with greater reliance on social media for health information (coef. = 0.42, p < .001), inversely related to use of medical websites (coef. = −0.21, p < .001), and not significantly related to use of providers for health information (coef. = −0.13, p = .061). In addition, liberal political orientation was negatively associated with acceptance of vaccine conspiracies (coef. = −0.29, p < .001).ConclusionsAn understanding of vaccine conspiracy acceptance requires a consideration of people’s health information sources. The greater susceptibility of political conservatives to conspiracy beliefs extends to the topic of vaccination.
    1. BackgroundAn invisible threat has visibly altered the world. Governments and key institutions have had to implement decisive responses to the danger posed by the coronavirus pandemic. Imposed change will increase the likelihood that alternative explanations take hold. In a proportion of the general population there may be strong scepticism, fear of being misled, and false conspiracy theories. Our objectives were to estimate the prevalence of conspiracy thinking about the pandemic and test associations with reduced adherence to government guidelines.MethodsA non-probability online survey with 2501 adults in England, quota sampled to match the population for age, gender, income, and region.ResultsApproximately 50% of this population showed little evidence of conspiracy thinking, 25% showed a degree of endorsement, 15% showed a consistent pattern of endorsement, and 10% had very high levels of endorsement. Higher levels of coronavirus conspiracy thinking were associated with less adherence to all government guidelines and less willingness to take diagnostic or antibody tests or to be vaccinated. Such ideas were also associated with paranoia, general vaccination conspiracy beliefs, climate change conspiracy belief, a conspiracy mentality, and distrust in institutions and professions. Holding coronavirus conspiracy beliefs was also associated with being more likely to share opinions.ConclusionsIn England there is appreciable endorsement of conspiracy beliefs about coronavirus. Such ideas do not appear confined to the fringes. The conspiracy beliefs connect to other forms of mistrust and are associated with less compliance with government guidelines and greater unwillingness to take up future tests and treatment.
    1. Background:In 2018, Facebook introduced Ad Archive as a platform to improve transparency in advertisements related to politics and “issues of national importance.” Vaccine-related Facebook advertising is publicly available for the first time. After measles outbreaks in the US brought renewed attention to the possible role of Facebook advertising in the spread of vaccine-related misinformation, Facebook announced steps to limit vaccine-related misinformation. This study serves as a baseline of advertising before new policies went into effect.Methods:Using the keyword ‘vaccine’, we searched Ad Archive on December 13, 2018 and again on February 22, 2019. We exported data for 505 advertisements. A team of annotators sorted advertisements by content: pro-vaccine, anti-vaccine, not relevant. We also conducted a thematic analysis of major advertising themes. We ran Mann-Whitney U tests to compare ad performance metrics.Results:309 advertisements were included in analysis with 163 (53%) pro-vaccine advertisements and 145 (47%) anti-vaccine advertisements. Despite a similar number of advertisements, the median number of ads per buyer was significantly higher for anti-vaccine ads. First time buyers are less likely to complete disclosure information and risk ad removal. Thematically, anti-vaccine advertising messages are relatively uniform and emphasize vaccine harms (55%). In contrast, pro-vaccine advertisements come from a diverse set of buyers (83 unique) with varied goals including promoting vaccination (49%), vaccine related philanthropy (15%), and vaccine related policy (14%).Conclusions:A small set of anti-vaccine advertisement buyers have leveraged Facebook advertisements to reach targeted audiences. By deeming all vaccine-related content an issue of “national importance,” Facebook has further the politicized vaccines. The implementation of a blanket disclosure policy also limits which ads can successfully run on Facebook. Under current policies, improving transparency and limiting misinformation are not separate goals. Public health communication efforts should consider the impact on Facebook users’ vaccine attitudes and behaviors.
    1. Since its very inception, the practice of mass vaccination has frequently met with ambivalence and occasionally encountered open resistance. For many health professionals, this opposition was and remains a mystery. How can parents deny their children a preventive treatment of such obvious individual and public benefit?
