A good, objective review and a very reasonable choice of words, all things considered: "the evidence suggests that all types of face coverings are, *to some extent*, effective in reducing transmission of SARS-CoV-2 in both HC & public, community settings". https://t.co/7DUD6BxemZ

Estudo avaliou diversos regimes heterólogos de vacinas contra o SARS-CoV-2; não há dados de eficácia, mas houve maior aumento na produção de anticorpos nos participantes 15 e 29 dias depois da dose de reforço com vacinas da Moderna e da Pfizer.

So yes, mRNA vaccines are great at generating antibodies but what does that mean? Where is the efficacy data? How come JnJ gets really great efficacy at preventing symptomatic COVID and severe disease with low antibodies? T-cells? Still much to learn. https://t.co/YwKUyogAhQ

#COVID19 has changed many things- one has been the way the public interacts with scientists.
Like many of my colleagues I was not prepared for the onslaught of harassment and it affected me deeply.

First dataset I have seen for vaccine efficacy in pregnant persons during #Delta era. Impressive aOR for both severe illness (0.11) and infection positivity in general (0.31)! #GetVaccinatedNow 🤰🏻💉 https://t.co/VhBHyeOWjz
