    1. no worse- he took Medley's comment that Sage model the scenarios the government asks them to consider to mean that they basically set out to find the justification for what the government already wanted to do. Complete failure to distinguish between inputs and outputs of a model
    2. one of the more depressing moments of pandemic discourse for me was recent exchange between @FraserNelson and @GrahamMedley where FN thought he had scored an amazing "gotcha" moment, when all exchange showed was FN not understanding what phrase "model a scenario" means..
    3. This is such an important point. You cannot look at data without a model. You cannot even look at anything in the world without a model--e.g. theory of mind, which only infants and people in a coma do without. All those model-bashers just reveal their ignorance @SciBeh
    1. BA.2 has a growth rate advantage over BA.1 of ca 0.11/day. That's quite sizeable. If it would have the same short generation time as BA.1 of 2.2 days it would imply a ca.1.3x higher transmissibility, due to higher contagiousness or immune escape.
    1. 47/ And finally, GBD, Tucker from AIER/Brownstone, Clare Craig from HART etc are operating in Uganda to increase vax hesitancy and build the antivax movement In how many other countries are they doing the same? Heinous
    1. 45/ And of course this can easily be debunked, Davis surely must have seen the corrections fill his TL, yet its still up and being quoted by others Doesn't help those falling for conspiracy theories to have MPs spreading this crap
    1. 35/ We see groups of politicians, media, astroturf, academics, the far right all coming into alignment and cooperation to undermine the pandemic effort with disinformation and political pressure on a weakened Prime Minister who only cares about his job
    1. 23/ Just look how Sunetra Gupta was silenced last week by writing an article in the Telegraph that reached a large audience. She now says herd immunity means constant reinfection, thats how we protect the vulnerable
    1. 21/ The CRG and the APPG sponsored by the GBDs Collateral Global fill the media with disinformation on a daily basis The APPGs recent attempts to halt vaccination of under 16s shows how far they've embraced the ideology
    1. 19/ More time and effort has been spent on gaslighting to keep measures out of schools than any other aspect of the pandemic It is after all the key part of a pro-infection herd immunity strategy Great read here on Bhattacharya
    1. 17/ What we are dealing with is not just a difference of opinion between experts, its deliberately muddying the waters and there seems to be concern that its the antivaxxers and conspiracy theorists who are lapping this up
    1. 10/ As a full time school worker the idea we can get back to normal in the short term is a joke The "toolkit" they've produced is another example of the weaponisation of mental health to support pro infection policies
    1. 6/ Having minimised covid harms, they find themselves playing down the benefits of vaccination For example in the US, Vinay Prasad has ended with messaging likely to increase hesitancy and embolden antivaxxers A look at an example of this
    1. 5/ There is a reoccurring theme of dividing children into "healthy" and "comordity" then dismissing concerns an individualistic approach to measures leaves vulnerable children greater risk Same vulnerable children they claim to champion when convenient
    1. 4/ These academics provide a statistical shield for policy makers to justify not taking transmission in schools seriously Their minimising of risks is also used by antivaxxers to reinforce their beliefs An example from US is Emily Oster
    1. 3/ Those minimising the impact on schools and children are an important part of the disinformation ecosystem Each country has a small group of over publicised academics fighting against all measures backed up by astroturf campaign groups
    1. 2/ As always theres been a focus in gaslighting around schools and children In the UK education is facing serious disruption due to a lack of measures so adults can pretend everythings back to normal while politicians still chase the herd immunity unicorn
    1. Two important updates from our team this week: - Vaccine effectiveness (VE) against symptomatic disease after Omicron BA.2 shows that VE remains unchanged - VE against death after Omicron BA.1 shows VE is 95% at 2+ weeks after booster 1/7 Full report
    1. Overall - these are great news. -Despite the increased prevalence of sub-lineage BA.2 in the UK, there does not appear to be a decrease in VE as compared to BA.1. - The booster vaccines remain effective against the most severe outcomes of Omicron infection.
    1. VE against mortality with Omicron BA.1 was estimated for those aged 50+ by combining the risk of becoming a symptomatic case with the risk of death among symptomatic cases in vaccinated (all vaccines combined) compared to unvaccinated individuals.
    1. Next, VE against death for Omicron BA.1. Although we have previously observed waning of the boosters against symptomatic disease during Omicron infection, protection of the boosters has been well maintained against severe disease when we have looked at hospitalisations.
    1. VE after 2 doses and after the booster dose was similar for BA.1 and BA.2. After 2 doses VE was 9% (7-10%) and 13% (-26-40%) respectively for BA.1 and BA.2, after 25+ weeks. This increased to 63% for BA.1 and 70% for BA.2 at 2+ weeks after a booster.
    1. First, VE against BA.2. The Omicron sub-lineage known as BA.2 was designated VUI-22JAN-01 on 19 January. VE against symptomatic disease was analysed in a test-negative case control design. Pillar 2 data from symptomatic cases tested between 27/12 & 21/01 were included. 2/7
    1. NEW: Vaccine effectiveness (symptomatic infection) data for BA.2 {Omicron’s more infectious sister} NO difference in VE between Omicron (BA.1) and BA.2 Possibly even higher VE for BA.2 but estimates overlap
    1. personally, I'd consider it a natural, considerate, and moral response to avoid contact with others when carrying an infection that can be dangerous to others. So what seems dystopian to me, is not doing so, and not creating the social/financial conditions that allow it.
    2. @DrJBhattarcharya's behavior is especially disgraceful because he has the credentials and appearance of a person doing this type of science, when in practice, he is engaged in sophistry to justify his predetermined conclusions.
    3. Policy issues are complex and difficult -- some of the best scientists (e.g. @ProfEmilyOster) look at the data for themselves and reach conclusions that are at odds with many epidemiologists. This work is essential.
    4. This experience casts in a new and more sinister light Jay's past policy mistakes, such as his claim that Covid mortality was substantially lower than epidemiologists believed and so Covid would lead to fewer deaths than a typical flu season:
    5. Despite admitting to me in private correspondence that focusing on the absolute reduction in risk was misleading relative to the proportional reduction, he did *exactly this* in the court case before he knew I would be there to correct him.
    6. Jay knows all of this since I messaged him privately to correct his misrepresentations, and he saw it all again when I testified in the trial to correct his misrepresentations but he keeps repeating his misleading statements in public forums.
    7. 3) The CI for Covid symptoms is a 7-17% reduction (from our 30 pp increase in masking). 4) Our standard errors for symptomatic seropositivity drop by half under alternative (equally plausible) ways of imputing missing values, w/ a CI of 6-20%.
    8. 1) We can rule out a zero effect w/ a p-value of .032 in the specification to which Jay refers 2) This is the *reduced form* from an increase in masking from 13% to 42%; so universal masking might be several times as effective
    9. He now summarizes our study in Newsweek by saying, "In a study in Bangladesh, the 95 percent confidence interval showed that masks reduced transmission between 0 percent and 18 percent. Hence, masks are either of zero or limited benefit."
    10. I recently testified pro bono in a trial about masking in schools (in my view, a complex question) for the sole purpose of explaining that the court should not trust @DrJBhattarcharya because he is deliberately misleading people about our study and others.
    11. It is sad. @DrJBhattarcharya is the worst example I have personally seen of someone who was previously a scholar but who now engages in repeated misrepresentation of scientific results to serve a partisan agenda.
    12. The sad thing is that @MartinKulldorff and @DrJBhattacharya once were taken seriously. I'm the last person to say Tony Fauci is always right, but these two have turned into parodies of their former selves. This is just embarassing.

    1. A new study has compared the amount of inaccurate COVID-19 information online early in the pandemic to the amount of misinformation about other health issues.The authors describe the abundance of COVID-19 misinformation as entirely predictable, based on the inaccuracy of other health information.An expert suggested to Medical News Today that people seeking information are considering more than just the reliability of the source.
    1. Ontario’s health minister is urging the regulatory body overseeing the province’s health professionals to crack down on a group of doctors spreading unverified medical information about the COVID-19 vaccines, after the situation was brought to light in a Global News investigation.

    1. COVID-19 cases have surged around the world lately leaving more people than ever infected with the virus. This has raised a lot of questions about immunity against future COVID infections and whether positive cases really get something of a “grace period” post-COVID where they’re extra protected. Swipe to close Let’s break down some of the facts and unknowns around COVID-19 immunity.
    1. This 4-part non-credit online course was designed with the input of NorQuest faculty to introduce students to concepts of misinformation and help them practice valuable critical thinking skills. The content is accessible, interactive and engaging. The following topics are addressed: Misinformation and it's various forms including fake news and disinformation Evaluating information using techniques such as lateral reading News literacy, science literacy and conspiracy theories The role of bias in spreading misinformation
    1. Arguments can be good or bad, and that difference is not just a matter of subjective preference. Rather, argumentation research has spent centuries identifying how and why some arguments are stronger than others. This includes understanding why some arguments (so-called ‘fallacies’) can fool the unwary into thinking they provide good reasons for believing or doing something when, in fact, they do not.
    1. With the Omicron variant spreading rapidly, the country is averaging more than 500,000 new cases a day, far more than at any previous point in the pandemic. Omicron appears to cause less severe illness than prior forms of the virus, but has contributed to upticks in hospitalizations.
