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…

Do COVID-19 vaccines promote the emergence of new variants?

COVID Variants Uncertainty and Misinformation Vaccines

A: No. Vaccines REDUCE opportunities for viral replication needed for variants to emerge. Since the recent Omicron news, we are hearing this myth make the rounds again. ➡️ TL;DR: The virus has more opportunity to replicate in unvaccinated populations, creating a FAR bigger risk for the development of SARS-CoV-2 mutations. Even so, the good news Read more…
