Bivalent booster shots are now available to protect against COVID-19. Bivalent means the vaccine offers protection against two different strains of COVID - including the Omicron variant.
Bivalent booster doses from both Moderna and Pfizer increase immune response in people who have completed a primary series and a previous booster.
Pfizer bivalent boosters are recommended for people 12 and older, and Moderna is recommended for people 18 and older.
