COVID-19 Science

COVID-19 Vaccines and Boosters
Everyone 5 years of age and older is now eligible to get a COVID-19 vaccination. Those 12 and older are eligible for a booster.

COVID Variants
Multiple variants of the virus - including Omicron and Delta - have been documented in the U.S. and globally.

When You've Been Fully Vaccinated
If you are fully vaccinated you can start doing many things that you had stopped doing because of the pandemic.

Antibodies and Immunity
Antibody tests may determine if someone had COVID-19, but immunity is uncertain.

Wearing Face Masks
Wearing a face covering limits the spread of respiratory droplets that could cause infection.
