COVID Variants Vaccines

A: No. COVID-19 vaccines are still acing their #1 job- preventing serious disease. TL;DR: Omicron is better at infecting people with immunity from vaccination or prior infection. But the vaccines (especially 3 doses) still *reduce* the risk of infection with Omicron, and *dramatically* reduce the risk of hospitalization and death. Vaccination is still the best Read more…

COVID Variants Vaccines

ā¬‡ļø 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 variantā€”about a 20-40-fold reduction in neutralization. While this is substantially more loss of neutralization than previous variantsā€¦this does NOT tell us how well the vaccines Read more…
