    Martin Kulldorff Retweeted Jake Tapper

    With open schools and no masks for ages 1-15 in Sweden, there were zero COVID deaths among its 1.8M children during first wave. Teachers had lower risk than average of other professions. So, we knew early on that schools are safe without masks. https://www.nejm.org/doi/full/10.1056/NEJMc2026670 …https://twitter.com/jaketapper/status/1428347738798891008 …

    2/ 2. While understanding masks are effectively generally at preventing transmission, I don’t know of any peer reviewed studies of mask mandates *in schools*. I get “better safe than sorry” but is there peer reviewed data? I haven’t seen any —

        Thankfully, we don’t let facts get in the way of ‘good’ policy.

        Edmund what do you think is driving this? It no longer makes sense to me how a large subset of medical experts can ignore empirical data and continue to double down on masks?

        Allegations in this smear piece has been refuted. Both by Swedish central statistics and by L in NEJM. Science journo Vogel tries very hard to make him seem suspect for asking Tegnell to help in getting cause of death stats that wasn't available then. Now it is.
