Two big exceptions: People treated for COVID-19 with monoclonal antibodies OR children who had multisystem inflammatory syndrome (MIS-C) need to wait at least 90 days.

THIS JUST IN: Preliminary Omicron neutralizing antibody study

COVID Variants Vaccines

⬇️ TL;DR: IN A LAB DISH (so NOT in real life), antibodies from vaccinated individuals (two doses of Pfizer-BioNTech), were significantly less effective at neutralizing Omicron compared to the original variant—about a 20-40-fold reduction in neutralization. While this is substantially more loss of neutralization than previous variants…this does NOT tell us how well the vaccines Read more…

CDC Updates Guidance for Boosters

Uncategorized

💥UPDATE💥: The U.S. CDC has updated its guidance to say that all adults over >18 SHOULD rather than MAY get a booster. As we wrote last week, we think the case for boosters is strong. Boosters provide increased neutralization of previously identified variants, which bodes well for Omicron. #BoostUp #VaxUp #WeCanDoThis Link to Original FB Read more…

Healthy Diet & Exercise vs. COVID Vaccination? Try both!

General Health Uncertainty and Misinformation Vaccines

We’re hearing so many people repeat this line: “just eat well and exercise, that’s the best prevention for COVID-19!” Is this true? Healthy diet and exercise *are* good for your health! Unfortunately, they do not really prevent COVID. The best prevention for COVID-19 is to be vaccinated. If you do get COVID, being vaccinated is Read more…
