Updated Bivalent Boosters Now Available Bivalent vaccines are updated booster vaccines that protect against the original strain of COVID-19 and the Omicron variants currently circulating (BA.4 and BA.5). Updated COVID-19 boosters can both help restore protection that has decreased since previous vaccination and provide broader protection against newer variants.
People age 12 and older are now recommended to get an updated bivalent booster dose at least 2 months after their final primary series dose or last booster shot.
The updated Pfizer booster is authorized for people age 12 and older.
The updated Moderna booster is authorized for people age 18 and older.
Everyone who is eligible—including those who are moderately or severely immunocompromised—are recommended to receive one dose of the updated vaccine.
The COVID-19 vaccines and the updated booster are safe and help protect people from getting very sick with COVID-19.
People can get COVID-19 vaccines, including updated boosters, at the same visit as other vaccines, such as flu vaccine.
