Emergency COVID-vaccine approvals pose a dilemma for scientists. It could complicate efforts to study long-term outcomes, such as safety, how long protection lasts and whether the jab prevents infection or just the disease

The #COVID19 response focuses on acute illness, but accumulating evidence shows morbidity beyond acute infection, with at least 2 other periods of illness: a rare postacute hyperinflammatory illness, and late inflammatory/viral sequelae https://t.co/mrf8WDxKY4 @jtsylee @CDCgov

Not perfect, nor confirmatory, but a good enough study to modulate the probability of a large self-efficacy from masks. Study powered to a 50% RRR, correctly concluded that it does not reduce infection by 50%. A negative study is negative only for the effect size it was powered https://t.co/aDPxRoIuqS

Today in @NatureNews with @d_spiegel & team we present “five rules for evidence communication”
1) Inform, not persuade
2) Offer balance but not false balance
