Everyone I know is getting Omicron. Does this mean the vaccines don’t work?

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

Why should we get a booster with the existing COVID vaccine when a new one is in the works for Omicron?

COVID Variants Vaccines

A: Boosters with the original Pfizer and Moderna vaccines increase protection against the omicron variant…NOW. A few weeks ago we posted on results from Pfizer showing that: 🔵 A third dose of the original Pfizer vaccine increased neutralizing antibody titers against the omicron variant by 25-fold, compared to levels seen with only two doses 🔵

Because of exponential math, even a small transmission advantage can quickly add up. This all goes back to evolution and math. Here’s how it works. A virus

Can our current COVID-19 diagnostics, like PCR tests and rapid antigen tests, detect the Omicron variant?

COVID Variants Testing and Contact Tracing

A: Good news. Standard diagnostic PCR tests can pick up the Omicron variant. As far as we know, most rapid antigen tests can also detect Omicron, but tests are ongoing to determine if any specific brands are less sensitive to Omicron. Stay tuned!
