It also has its limitations, most importantly their dependence on the availability of sufficiently large and diverged sequence ensembles. In fact, we observe that a greater number of sequences usually increases the performance of the approach (Fig. 4C and S10). However, it is important to note that the inclusion of more divergent sequences might not always be the best strategy as the model might capture constraints that are not relevant for the specific SARS-CoV-2 context. This trade-off will be explored in future work. Our approach can be extended in several ways. One is to include how different domains might constrain the variability of other domains. However, according to our analysis in the previous section, inter-domain epistasis seems to play only a minor role, even if more sequence data might be needed to better estimate the influence of inter-domain or inter-protein epistasis. Another is to model constraints due to specific virus-host interaction, which is currently out of our scope, as we do not consider host sequences in the MSAs. Indeed, we observe the correlation of experimental binding to ACE2 and our predictions (Pearson’s r = 0.27) can be fully explained through the protein expression (Pearson’s r partial correlation controlled by expression = −0.02). In an attempt to explore this issue, we built co-alignments of receptor-binding domains with homologs of ACE2 present in the hosts of other coronaviruses. Since the binding mechanism between RBD and ACE2 homologs ...

A limitation of the analysis is that vaccinated individuals which lose their vaccine induced protection are assumed to have the same characteristics as non-vaccinated individuals within the same age-group. In a similar way, we assume that individuals who receive a booster shot are equally protected to those who have been vaccinated with a full scheme. Recent studies suggest that a third-dose booster shot increases vaccine protection to levels similar to receiving a complete scheme [35, 36] which is in line with the present assumptions. Our results show that vaccine effectiveness, coverage, vaccination speed and vaccine induced protection waning play key roles in understanding disease spread and healthcare impact. Currently, vaccine allocation, effectiveness and coverage in Portugal has not been enough to control disease spread. Hence, NPIs should be maintained and combined with vaccination programmes that include more age-groups and booster doses. Vaccine effectiveness should be monitored in order to assess scenarios for the periodicity of booster shots. As more data becomes available we will extend the present model to study optimal booster dose schedules according to different scenarios of vaccine induced protection waning and infection induced immunity waning and the impact of new VOC.

The limitation of our study is that our data did not include genome sequencing data of the virus so that we could not differentiate between reinfection or reactivation of the virus. Nevertheless, the three months difference between each PCR test provided in the diagnosis data has been accepted as a period that is possible for reinfection because of the reduction of antibodies, yet the least possible for reactivation.

As with all observational analyses, this study has limitations. Notably, without randomizing interventions, it is difficult to identify a singular cause driving these trends. Several hypotheses would be consistent with these data, including: (1) the SARS-CoV-2 Delta strain shifted the importance of intrinsic risk factors, (2) successful efforts for early detection and treatment of thrombosis risk [16] widened the difference in mortality risk between a serologically defined prothrombotic state and active thromboses, (3) potential interactions between anti-inflammation treatments and haemostasis, vascular function, and thrombophilic propensity [14,15], or (4) a lack of effective thromboprophylaxis treatments in Covid-19: there is little evidence for thromboprophylaxis from heparin in Covid-19 patients [12,13] which may be due to heparin’s reliance on endogenous Antithrombin (AT) [17] which can be reduced in Covid-19 patients [18] --- anticoagulants such as Argatroban [19] or Bivalirudin [20] which do not rely on AT may exert more powerful thromboprophylaxis than heparin in Covid-19 patients, or (5) an alternate process linked to thrombosis risk factors but also potentially implicating other aspects of endothelial and vascular dysfunction. All in all, our results suggest that it may be beneficial to focus more research on patients who have thrombosis or are at high thrombotic risk.

Firstly, limitations in data completeness meant that we were only able to analyse onboarding data for one quarter of CCGs across England. This, combined with lower than expected coverage within these CCGs, meant that our ability to detect any possible impact was smaller than anticipated. This also meant that some areas of the country were under-represented. Secondly, individual level associations may not have been seen at the aggregate level. Thirdly, qualitative findings from our wider study revealed that COVID oximetry @home was implemented in a variety of ways by different services within CCGs, some of which may have had more impact on outcomes than others.6 The possible impact of the intervention on hospital admissions was always uncertain, since the aim of the programme was to ensure people who needed hospital treatment were admitted at the right time. Also, once in hospital, the determinants of length of stay are complex and multifactorial, and may have varied during the time course of the second wave of COVID-19 infection in England. Strengths and limitations: The anticipated value of our approach with aggregated data was that it would complement the other two simultaneous quantitative evaluations of CO@h,10,11 could be carried out more rapidly and, if COVID-19 continues to stretch national health services, it could be more readily repeated as new data become available, provided the right information is routinely collected at source.

Our study has some limitations, the cohort includes only active healthy workers, without severe comorbidities, and all participants are under 70 years old, with over representation of the female population. The occupational risk is reduced, although the majority of the participants manipulate SARS-CoV-2 positive samples, strict guidelines to use individual protective equipment limit the occupational risk exposure being reduced compared to medical personnel with close contact with patients. The heterogeneity in the reference units to quantify the detected antibodies posed a difficulty to compare our data with other studies. Few studies used the same units that we used in this study. This point was already highlighted by Earle et al., [11] that suggested the use of the WHO International Standard (NIBSC 20/136) to express neutralizing antibodies titers in IU/mL and binding antibodies titers in BAU/mL to be possible to compare data among different studies using serology assays, in the context of COVID-19 pandemic. Given the importance to compare different vaccines among different populations to help to design new strategies to battle the pandemic, this point is crucial to a better comprehension of data obtained around the world. We didn’t explore the antibody titers for variants of concern, and a decrease of antibody titers could be expected. The cellular immunity and other immunological mechanisms weren’t explored during the study. In our study, we found a high correlation betwe...

Our study has several strengths and limitations. We followed a large cohort of patients in a longitudinal design at 3, 6, and 12 months after hospital discharge. Currently, long-term follow-up data are scarce. As the study is still ongoing, data were not complete for the entire cohort; also, the initial patients were generally recruited between 3 and 6 months after hospital discharge, resulting in unequal groups at different time points. We therefore included only participants with data of at least two study measurements, and used GEE models to make maximal use of all data and to investigate how symptoms developed over time. One inclusion criterium was that patients or their relatives had to be able to communicate in Dutch or English. Therefore, there is underrepresentation of individuals with a migration background in this study compared to the community where this cohort was established. Nonetheless, 24% of the participants in this cohort had a migration background; migration background was not a predictor of residual symptoms in this study. Another limitation is that our results are only generalizable to hospitalized patients. Also, we did not have patient scores on the severity of complaints. Even though symptoms may persist for considerable time, the severity may very well decrease over time, as was also shown in other studies (16). To summarize, a large number of post COVID-19 patients experienced persistent symptoms up to 12 months after hospitalization for COVID-19. W...

There were several limitations inherent to our study. First, district participation was incomplete and varied weekly, leading us to rely primarily on last-reported-week data. While higher and more regular participation would improve generalizability, we are thankful for voluntary survey responses by district staff already working tirelessly to implement both virtual and in-person learning during the pandemic. Second, questions about the personnel number and hours spent offered responses only in strata (e.g., 1-5 hours; 10-15 people). Our cost estimates assumed the mid-point of these ranges, although use of upper and lower bounds did not substantially change results. Third, we assigned hourly wages for parents and volunteers based on a state-wide estimate of hourly wage;30 local opportunity costs may have differed. Fourth, costs reported here do not include the materials needed at school to administer tests, including disposable gloves, hand sanitizer, cleaning supplies, and personal protective equipment for staff.36,48 Importantly, the 21 districts in this study include a lower proportion of Black and Hispanic students, English-language learners, and economically disadvantaged students than the state-wide average. While the costs of assays will likely be similar in most settings, resources needed for implementation may differ widely, for example, the availability of parent volunteers and the time needed for outreach, education, and obtaining consent for all participating stud...

Several limitations and caveats apply to our computed structural models and analyses. First, post-translational modifications such as glycosylation, which may often be a key element of Spike structure, are not considered in our protein-only models. Many experimental structure determinations also exclude these glycans, and multiple X-ray structures show that the ACE2-binding interface does not explicitly involve glycans. However, some glycosylation patterns do affect binding of certain antibodies. Second, we do not include explicit interfacial water molecules in our modeling procedures. There were no major water-mediated interactions observed experimentally in the complexes we analyzed in detail. However, it is conceivable that new water-mediated interactions have been missed. Both limitations can be addressed by using the models reported here as starting points for more computationally-expensive modeling approaches (such as molecular dynamics simulations) with appropriately glycosylated amino acid sidechains.50 In addition to these limitations inherent to modeling procedures, there are well-known limitations of the energy functions used for scoring and energy evaluations plus the limited conformational sampling that is performed in the interest of computational efficiency. Because the overall structure of omRBD is likely to be highly similar to the Wuhan-Hu-1 RBD, limited sampling around the conformations observed in experimentally-derived structures represents a reasonable t...

In this sense, vaccination in BC patients is recommended, consistent with the Chinese expert consensus on COVID-19 vaccination for BC patients, unless patients were receiving several adjuvant treatments such as radiotherapy, chemotherapy, targeted therapy.[9] This study has limitations, including its cross-sectional nature, reliance on self-reported data, and limited demographical data. Yet the study has enough data to shed light on the vaccination uptake in Chinese patients with benign breast diseases and breast cancer, suggesting a full-dose vaccination campaign for most of breast diseases patients (except for breast cancer during adjuvant treatment or in the advanced stage) tolerable for vaccination may protect them from unnecessary morbidity and mortality from SARS-CoV-2 infection. Since vaccination remains the leading strategy for preventing severe adverse outcomes. The active participation of oncologists is needed to further educate patients with breast diseases about the benefits and indications of COVID-19 vaccines, especially for those without vaccine-contraindication.

Caveats: The fundamental assumption in our analysis is that the abundance of vaccine reactive TCR α and β clones corresponds to binding efficiency to their cognate viral epitope. Implicit in this assumption is that there is an approximately one-to-one mapping between TCR CDR3 and epitopes. Clustering CDR3 by homology (Methods) did not affect our trees, nor did it significantly change the number of reactive clones but clustering in this manner might also not be sufficient in any case, since it might not identify all clones with common epitope targets, as there are cases where non-homologous clones that share targets, and homologous clones that have completely different targets.

However, this study does have some limitations. First, using data from this community-based cohort study we were not powered to detect the most severe manifestations of SARS-CoV-2 including death or Multisystem Inflammatory Syndrome in Children (MIS-C) and other rare outcomes. (15, 16) Second, our analysis did not include genetic sequencing preventing us from assessing the importance of variants in presentation and severity of SARS-CoV-2 illness. We did compare SARS-CoV-2 symptom presentation, severity, and duration by year and found little or no difference. Finally, while our study does not evaluate asymptomatic illness for endemic HCoVs, our results were consistent with other research, showing that childhood HCoVs are ubiquitous and that symptomatic cases represent only a small proportion of infections, as with SARS-CoV-2. (12) In this study, we observed that symptomatic SARS-CoV-2 infections at the community level are very similar to symptomatic endemic HCoV infections in symptom presentation. Among children in a setting with a high SARS-CoV-2 infection rate, symptomatic SARS-CoV-2 infections are on average as or less severe as endemic HCoV infections. These findings support the hypothesis that SARS-CoV-2 may be like another endemic HCoV for children—most children will be asymptomatic with rare cases of severe symptomatic illness. This does not mean SARS-CoV-2 in children is not important. There are many unknowns about the long-term effects and impact of repeat infections ...

However, again this would need to be tested using biopsy/autopsy specimens or other mechanistic studies Our study should be interpreted in the context of certain limitations. First, samples were collected during the hospital course of patients with confirmed COVID-19. However, the timepoints were not systematic due to logistical challenges during the peak of the COVID-19 pandemic and thus are not standardized between patients. Since a subset of patients had AKI at the time of admission, these patients were excluded from our analysis since specimens were collected after admission. Thus, our AKI cases may be biased towards less severe presentations. Second, since kidney injury is usually not an isolated phenomenon in critically ill patients, the protein expression changes observed may have been partially due to damage to other organs, such as the lung, liver, and heart. However, we accounted for non-kidney damage by adjusting for the highest level of ventilatory support and thus our results are likely a reflection of kidney injury. However, our results do show the importance of crosstalk between the cardiac system and the kidneys. Finally, our cohort did not include autopsy or kidney biopsy specimens. Histopathological analysis of kidney specimens is necessary to determine the mechanism of AKI and whether viral particles are present in the kidney. In conclusion, we provide the first comprehensive characterization of the plasma proteome of AKI and long term eGFR decline in hospi...

These results should be interpreted in the context of several important caveats. First, and foremost, neutralizing antibody titers are a surrogate for VE, and despite strong correlations between VE and neutralizing antibody titers (4-7), direct studies of VE are critical to determine the full extent of immune evasion of new variants. Specifically, our analyses assume that differences in disease severity of variants are correlated with differences in neutralizing antibody titers. Whether this will hold across the 40-fold reduction in neutralizing antibody titers is highly uncertain. Second, the extent of Omicron immune evasion is so large relative to previous variants (40-fold vs 7-fold for Beta), and VE estimates for the next most evasive variant, Beta, were so uncertain that we were unable to estimate vaccine-specific models to estimate VE for Omicron. Instead we assumed that differences in neutralizing antibody titers across vaccines and variants are suitable for estimating VE across variants. Third, the 40-fold reduction that we used for Omicron required extrapolation well outside of available data and prevented us from providing reliable VE estimates for Omicron for vaccinees with waned immunity. The Omicron variant of SARS-CoV-2 has grown rapidly in many countries. We have shown that the approximately 40-fold reduction in neutralizing antibody titers greatly erodes vaccine protection and increases the relative risk of infection and symptomatic disease more than four-fold...

Our study has several limitations. The type of research and the clinical/scientific areas studied were based on definitions that may not be collectively exhaustive and mutually exclusive. In addition, we only reviewed abstracts and did not review the entire funded proposals. There were other barriers to clinical research that were not captured here, including slow institutional review boards and long journal peer-review times. A rapid research protocol that protects research subjects with standard ethical principles for research could be developed for the next health emergency.

With this mind, this work is not without limitations. The underlying transmission model is deterministic and does not account for demographic stochasticity and over-dispersion in transmission which has been documented in SARS-CoV-2 transmission [17]. As with all methods which depend on parameterizations of the generation time, misspecification of the generation time can be lead to biased estimates of the effective reproduction number or growth advantages [18]. In order to quantify this source of error, we derive an equation relating our inferred growth advantages, the epidemic growth rates, and the mean and standard deviation of the generation time distribution. This source of error can be partially combatted by converting effective reproduction numbers to their corresponding epidemic growth rates under the generation time assumption. (see Supplement Appendix) There is also a general need to account for biases in the case data which may not faithfully describe the infection dynamics of SARS-CoV-2 due to changes in case ascertainment rate, as possibly caused by differences in testing intensity, infection severity among other reasons. However, we suspect that case ascertainment remained largely consistent from January to October 2021. We do not explicitly model multiple introductions of variants which can play an important role in variants establishing themselves in different geographies at low infection counts and could bias our estimates of the effective reproduction number i...

Limitations: In addition to the limitations already discussed, we did not collect detailed clinical data on all the reinfection cases to assess disease severity compared to the primary infection. Among hospitalised cases, too, we were unable to distinguish whether the children were hospitalised for COVID-19 or the virus was identified incidentally during routine screening of children attending hospital for other illnesses. The emergence of new variants also made it difficult to assess waning of natural immunity over time. As children continue to be vaccinated against COVID-19, it will become more difficult to assess long-term protection after natural infection.

This study is not without limitations. This survey was conducted early during the pandemic but after the shutdown mandate was removed in most states. Thus, the sentiments and stressors may have changed over time. This study also assessed marital status with childcare and clinical responsibility allocations. While there was a majority correlation, it should be noted that our respondent population was majority married with children, thus impacting the generalizability of our results. The data collected also consisted of majority Caucasian women, so differences across ethnic groups and perceptions cannot be generalized, and significant correlations could not be made. In addition, as only females were surveyed, adequate correlations to men’s perceptions of the COVID-19 impact were not collected. While many women stated their concerns of being compared to their colleagues or unfair advantages, we cannot say for certain that men do not also hold similar concerns, or that it solely applies to women. Men may also have financial concerns, time management and family obligations or childcare responsibilities that were not noted in this study. In addition, we could not identify a normative comparator group to compare levels of stress and anxiety to. This is because every field is highly specialized and results from one group may not be applicable to others. Yet, it is still important to emphasize the pandemic concerns mentioned in this study to better establish policies and support netwo...

There are a number of study limitations. Serum samples were collected from patients hospitalised with SARS-CoV-2 for clinical diagnostic tests during the first wave of the pandemic in the UK. Due to the clinical pressures within the system at the time some clinical data, such as BMI, was not collected. It is known that levels of SPMs are decreased with increased BMI, which could potentially contribute to SARS-CoV-2 related morbidities and mortalities[40]. Although we have data relating to whether a patient was admitted to intensive care, clinical decision making was related to multiple factors beyond the severity of the infection and therefore further analysis of potential impact has not been performed. Serum samples were collected within the first few days of hospital admission and represent a snapshot of the anti-nucleocapsid and anti-spike response and the lipid levels at a point in time. It is important to note that levels of antibodies change over time, however we do not have matched longitudinal data. The anti-nucleocapsid and anti-spike signal provides an indication of the potency of the adaptive immune response following infection. The viral genome sequencing data available for these patients indicated that the nucleocapsid amino acid sequence was completely conserved between infections. While it is possible that there may be mismatches between the antigen used in our assay and the strain of infecting virus that mean that antibodies are present which are undetected by...

Strengths and limitations: The strengths of the study include a complex and inclusive recruitment strategy, allowing interested people enough time to join the study and regular (monthly) follow-ups throughout the second and third waves of the COVID-19 pandemic. We also have a much larger sample size than previous studies from Sweden (close to 28,000 compared to 1,503 in Rondung, Leiler, Meurling, & Bjártå (2021) and 1,212 in McCracken, Badinlou, Buhrman, & Brocki (2020)). Our study also has limitations. First, while the survey has been open to all, selection bias cannot be neglected. More than 80% of the sample were women which is partly because women are more likely to participate in survey research but also because the KARMA cohort (contributing over 5,500 participants) is made up entirely by women. Moreover, the younger age groups were under-represented. Further, recruitment type (through personal invitation or self-recruitment through social media and other outreach activities) was strongly related to mental health outcomes. For this reason, we corrected all analyses and figures for these factors (age, sex, and recruitment type). However, leftover influence of these factors might still have impacted the results to some extent. Regardless, the fact that over 43% of the participants scored above cut-off values of at least one of the mental health measures indicates the notable mental health burden of COVID-19. This is very close to the 45.6% reported by McCracken and collea...

Notwithstanding this limitation, we have provided a ‘proof of concept’ of how baseline infection risk data can be used to calculate the NNE to evaluate the benefits of excluding unvaccinated people to reduce SARS-CoV-2 transmissions. Future research should focus on developing an online interactive global database of the NNEs and baseline infection risks in each region which is regularly updated. Furthermore, this interactive database should be linked to regional vaccination rates, SARS-CoV-2-related hospitalizations/deaths, hospital/ICU occupancy, and the basic and effective reproduction number to contextualize the NNEs within other important metrics. This would be helpful for societies and policymakers to evaluate in real-time the harms vs. benefits of excluding unvaccinated people. Health economic analyses are also needed to analyze the cost-effectiveness and cost-benefits of excluding unvaccinated people. Future studies could incorporate vaccine/natural immunity data into the model to explore the impact of herd immunity on the NNE. Finally, when new variants emerge (e.g., Omicron) and potentially outcompete the Delta variant, the NNEs should be updated with the transmissibility data of future dominant variants.

Despite these important insights, our study also has several limitations which should be considered in its interpretation. Adverse events under SARS-CoV-2 vaccination were not the primary endpoint of this study. Therefore, sample size was not optimized for this endpoint and our trial is not powered to estimate the exact frequency of rare AE under ICT and COVID-19 vaccination. Moreover, AE were assessed upon presentation at our day clinic every 1-6 weeks and not at a standardized early timepoint as performed for randomized controlled vaccination trials (Polack et al., 2020). While serious AEs were generally reported instantly, lower grade AEs may be underreported due to recall bias. Finally, all serum cytokine and antibody titer analyses are research grade and absolute concentrations from this study should not be used to establish clinical diagnoses. Strengths of our analysis include the prospective design, prospective recruitment of most patients, long-term follow-up, broad array of cancer types and combination ICTs. In summary, induction of CRS-related cytokines after COVID-19 vaccination is common in ICT-treated cancer patients, but generally clinically inapparent and hence not sufficient to define CRS. Our study supports current clinical practice of COVID-19 vaccination in cancer patients under ICT.

This is a possible limitation of this study, applicable mainly to the endpoint of confirmed infection and to the lesser extent to the hospitalisation or death endpoints. The one-dose Janssen vaccine appears in our analysis to defy the general trend of protection decay and while it starts at a significantly lower effectiveness, it holds it over the six months analysed in this study. To our knowledge, this somewhat counter-intuitive result has not yet been reported and as such it is not easy to interpret. However, due to the fact that this vaccine was introduced to the Czech Republic much later than the other three vaccines and that it requires only one dose for a complete vaccination, it is plausible to assume that this vaccine was mostly chosen by people with different social and behavioural characteristics compared to the two-dose vaccines. Since we cannot support this suggestion with data at the moment we leave this as a suggestion for further studies. Our results show that the administration of booster doses of the two approved mRNA vaccines brings the observed effectiveness to above 90% for infections, hospital admissions and deaths alike. Booster doses are undoubtedly highly efficient to prevent serious or fatal infections. Although our results are in a general agreement with the study on protective effect of vaccine booster in Israel (Bar-On and others, 2021), we cover a more extensive period of booster applications, use of the Spikevax vaccine as a booster, and do not ...

There are at least four limitations to this study. First, persons who were infected with SARS-CoV-2 in 2020 but who were not tested (e.g., due to limited testing availability) could not be included. Thus, our analysis of 1,048 first reinfections during June 15–August 31, 2021 among those initially infected in 2020 is an undercount, reducing sample size and precision of estimates. Because symptom status was missing for a quarter of reinfected individuals, the number of symptomatic reinfections was also an undercount. Further, our study population was likely biased toward those with more severe illnesses from initial infection (i.e., those who were hospitalized and thus eligible to access testing during the first wave of infections), which might have resulted in a population with stronger infection-induced immunity [26]. Second, some NYC residents were more likely to be repeatedly tested (e.g., as an occupational requirement particularly if unvaccinated), increasing the probability of ascertaining mild initial infections and/or reinfections. Further, if vaccinated persons were less likely to be tested, then given disproportionate ascertainment of reinfections among unvaccinated persons, VE could be overestimated. However, by assessing VE for symptomatic reinfection and for reinfection with hospitalization, we reduced this potential ascertainment bias from discretionary testing for non-clinical reasons. Third, exposure misclassification is possible because persons vaccinated out...

While our data suggest a lack of sensitivity to humidity and temperature, we caution against over-interpretation of these data given the limitations inherent in our experimental system. A detailed understanding of the host, viral and environmental factors that shape transmission efficiency is of fundamental importance to efforts to elucidate the drivers of SARS-CoV-2 dynamics across spatial-temporal scales. This knowledge in turn is invaluable for refining strategies to interrupt transmission. Our data reveal that the timing of exposure is a potent determinant of transmission potential and point to viral load as the underlying driver of this effect.

As noted in other predictive modeling studies on COVID-19, there are some challenges and limitations of predictive models. Data obtained early on in epidemics may be limited due to under-detection of cases, inconsistent detection of cases, reporting delays, and poor documentation–all of which affect the quality of model output.39 This is particularly true of the COVID-19 pandemic, where numerous cases were asymptomatic, leading to varying hypotheses as to the true prevalence of COVID-19 due to undetected cases.40 Predictive models lead to the possible exclusion of undocumented, unconfirmed cases due to lack of access to medical care, which could then lead to under-representation of some of the most vulnerable populations.41,42 Another limitation may be potential bias due to factors such as the accuracy of diagnostic tests, lasting immunity, reinfections, and population characteristics.39 The limitations of the present study are now stated as follows: he comorbidities of the chronic diseases were unknown because the data were only reflected with yes, no, and unknown; the GDPH did not release any gender specific data for cases and chronic diseases for race/ethnicity; and there were a very limited number of unidentified datasets publicly available. The study findings will help for interventions and develop policy briefs for future of pandemic, and they can be generalized to the population with geographic and gender-and race-specific similarities.

Strengths and limitations: We used both empirical analyses and simulations to comprehensively investigate the potential presence and impact of selection bias in COVID-19 studies. We used two cohorts with pre-pandemic data allowing us to identify potential determinants of selection. We were able to compare across these cohorts that have contrasting sources of COVID-19 data (from questionnaires in ALSPAC and national registries in UKB). In addition, a strength of our simulations is that we based most of the parameters on either cohort data or other secondary sources to try to reflect realistic scenarios. In the analyses presented here we make several assumptions about or simplifications of the data. Both ALSPAC and UKB are subject to pre-pandemic selection bias due to non-random recruitment into these studies and loss to follow-up, which we do not account for here. Overall, we considered misclassification of the comparison groups (e.g. infected as non-infected) but not of the case groups (e.g. non-infected as infected). This may be particularly problematic for self-reported COVID-19 data and cause of death attributed to COVID-19 early in the pandemic [23]. We have focussed analyses here on the first wave of the COVID-19 pandemic in the UK.

There are several limitations and strength of our study. First, we have few patients that were exposed in the first trimester. However, this is balanced against a significant strength of our study in that the participants were matched by timing of vaccine or live viral exposure during pregnancy, allowing direct comparison of vaccine-induced and natural immunity in pregnancy and different timepoints in pregnancy. Second, we do not have sequencing data for the natural infection cohort, and thus do not know which strains caused the infection. However, all infected patients tested positive before January 2021, prior to broad circulation of the Alpha and Delta variants in the United States (60, 61). Presumably, individuals infected with the Delta variant would have higher specific nAb activity against this strain and may also have differing responses to the other variants. Future studies would be helpful to understand the immunogenicity evoked by the Delta, Mu, and other variants in pregnancy. Third, detailed antibody characterization, such as IgG subtyping or fucosylation state, is needed to understand the role of these factors in the dynamics of maternal-fetal antibody transfer. This should be addressed in future studies. In conclusion, vaccination in pregnancy is highly effective in generating nAbs against all strains of SARS-CoV-2 tested, although activities against the Kappa, Delta, and Mu variants are reduced. Vaccine-induced neutralizing activity is comparable to natural im...

Strengths and limitations: The strength of this study is the longitudinal assessment of SARS-CoV-2 infection and transmission in secondary schools. One limitation was the large numbers of students self-isolating during the final sampling visit in June/July 2021. This will have contributed to the apparent low infection rates on Round 4 school testing day, but linkage with national testing data found only 1.5% of students who did not take part in Round 4 had a confirmed COVID-19, indicating that most students were self-isolating because they had been a contact of a case. Reassuringly, though, the lower number of participants tested in Round 4 will not have impacted on seroprevalence and seroconversion rates between Rounds 3-4 because of the delay in developing an antibody response after infection and, therefore, the antibody tests performed in Round 4 would reflect infection rates at least 2-4 weeks prior to testing. Given the continuing high SARS-CoV-2 infection rates in teenagers throughout the summer months and beyond, and with COVID-19 vaccination now recommended for teenagers, it is likely that our antibody positivity rates significantly underestimate current seroprevalence. Another limitation is that participation among staff also fell during the final round, mainly because most of them were vaccinated and no longer saw study participation as an opportunity to confirm their immunity status.

With the above caveats, we could make the following conclusions. Despite a 40-fold decrease in virus neutralisation, full primary vaccination with Comirnaty could be highly protective against Omicron, with the symptomatic effectiveness almost 60% for up to 5 months. Even with the Worst-Case scenario (120x decrease), two doses could still have a sizeable effectiveness of 42% (although note a potentially high prediction uncertainty at low titres). This implies that boosters might not need to be radically sped up for every population group. Protection after the third dose would be substantially stronger across all the scenarios considered, given the likely neutralisation increase relative to the second dose. In fact, the assumed 3.3-fold increase could be too conservative, given the 20x (15, 27) increase reported in Atmar et al. [2021] for homological Comirnaty boosting, and the 25x increase from the early data in Pfizer/BioNTech [2021] on Omicron pseudovirus neutralisation. The symptomatic effectiveness, predicted here for general adult populations, is likely to be higher in adolescents and young adults. The effectiveness against severe disease, hospitalisation and death is likely to exceed the predicted symptomatic effectiveness. If the early reports, such as [Chutel et al., 2021], that Omicron causes milder disease are confirmed, then the effectiveness could increase across the board. Still, waning protection, especially after primary vaccination, will put a downward pressure...

Our study has some limitations that need to be addressed; First, despite the extensive sampling protocol, it is possible that SARS-CoV-2 infections were underdetected to some extent due to missing outbreak samples or asymptomatic infections in-between screenings. Sample completeness was high for the initial outbreak samples, but declined thereafter and convalescent serology was only available for 48.8% and 63.3% of subjects in SARS-CoV-2 positive and negative outbreaks, respectively. We therefore believe that the incidence and attack rates reported in this study should be interpreted as minimum values, rather than averages. Similarly, the true proportion of asymptomatic infections could be somewhat higher than estimated in this study. Second, a large fraction of the observation time fell in the period when the alpha variant of SARS-CoV-2 was dominant in the Netherlands. The period of extended follow-up mostly covered a period with dominance of the Delta variant. Although symptomatology appears not to be different for alpha versus delta, it is possible that household transmission rates were higher during delta dominance, which is only minimally captured in our data (three SARS-CoV-2 outbreaks were studied during extended follow-up). Alternatively, more parents received COVID-19 vaccination during the extended follow-up period and this most likely lowered infection rates among these households. It is unlikely that vaccination had significant impact on the results of the core st...

Strengths and limitations of this study: Strengths of this study include the large overall sample size covering multiple test sites nationwide, collection of samples for the reference and two Ag-RDTs in the same individuals within a few hours allowing for a head-to-head comparison of the two self-tests, sampling done by the participants themselves without any supervision conform the real-world context of self-testing, blinding of the index for the reference test result and vice versa, and the use of a proxy for infectiousness. Furthermore, the follow-up information showed that very few infections were missed by the molecular reference tests. Our study also has some limitations. First, the reference standards that we used were molecular tests, but platforms and test kits used differed among the centralized laboratories. However, the diagnostic accuracies of all molecular tests used are similarly high25,26, and we therefore believe that this has not influenced our findings significantly. In addition, Ct values used to calculate viral loads were determined by different yet comparable platforms (supplementary material 3). Second, we used the viral load cut-off above which 95% of people with a positive RT-PCR test result had a positive virus culture as a proxy of infectiousness. Although this cut-off is not fully evidence based3, it is a best estimate based on current knowledge, and less arbitrary than using Ct cut-offs of 25 or 30 as is often done.27,28 In the current study, we r...

As a result, a second generation of antibodies might be required to overcome these limitations and could be obtained by reshaping the initial sequences by conferring them the necessary properties, such as affinity and selectivity, to have optimal therapeutic efficacy for treatment in humans. From this perspective, many teams have proposed a wide range of methods to generate candidates with the expected properties, mostly increased affinity.29-32 Affinity maturation aims at improving biological activity by adjusting the kinetic parameters of the binding to the target, which in turn may confer greater therapeutic efficacy.25,33 However, the magnitude of this effect depends largely on the epitope recognized by the antibody and the initial affinity along with the format of the antibody and its valence.25 In the context of the current COVID-19 pandemic, several studies have described affinity maturation of VHH or conventional antibodies to enhance their binding to SARS-CoV-2 antigens, by CDR-swapping approaches 34, saturation mutagenesis in CDRs 35,36 or light-chain shuffling36. In recent years, Deep Mutational Scanning (DMS) approaches have emerged as a powerful tool for understanding protein/protein interactions. Deep Mutational Scanning (DMS) explores in a selected protein all possible unique substitutions, i.e. all unique mutations for each position. DMS defines mutational landscape of the protein and helps to understand the interaction modalities as recently shown for the RBD...

A caveat of the present study is lack of WT SARS-CoV-2 challenge controls in the hamster experiments, which could be used for direct comparison with the delta challenge. However, based on previous preclinical testing of BNT162b2 and mRNA-1273 using WT virus, both mRNA-S vaccines were found to be highly effective in controlling WT SARS-CoV-2 in both upper and lower respiratory tracts [5, 8]. In addition, our analyses of serum neutralizing activity against WT and delta strains in parallel (Fig. 4h) also supported these observations as sera of mRNA-S vaccinated hamsters manifested reduced neutralizing activities by ∼5-fold against the delta strain compared to WT virus. A major finding of our study is that combinatorial mRNA-S+N vaccination led to significant increase in control of the SARS-CoV-2 delta strain infection in the lungs (Fig. 3b) and in the upper respiratory tract (Fig. 3c). Notably, combinatorial vaccination induced an additional 10-fold reduction in viral RNA copies compared to the mRNA-S alone (∼450-fold reduction in the lungs compared to the mock-vaccinated control at 2 DPI) and led to a faster resolution of the infection, indicating that this vaccine approach likely provides even better protection from the disease caused by delta. Furthermore, combinatorial vaccination also induced stronger viral control in the upper respiratory tract (by additional 4-fold compared to mRNA-S alone) (Fig. 3c), albeit to lesser extent than that in the lung. This finding indicates t...
