On September 1, 2022, the CDC issued new recommendations for COVID-19 boosters, after the FDA authorized updated booster formulas from both Pfizer and Moderna. The CDC recommends that everyone who is eligible stay up-to-date on vaccinations by getting an updated booster dose at least 2 months after their last COVID-19 shot—either since their last booster dose, or since completing their primary series. Pfizer’s updated booster shot is recommended for individuals 12 and older, and Moderna’s updated booster shot is recommended for adults 18 and older. 

These new boosters contain an updated bivalent formula that both boosts immunity against the original coronavirus strain and also protects against the newer Omicron variants that account for most of the current cases. Updated boosters are intended to provide optimal protection against the virus and address waning vaccine effectiveness over time.

Eligible individuals can get either the Pfizer or Moderna updated booster, regardless of whether their primary series or most recent dose was with Pfizer, Moderna, Novavax, or the Johnson & Johnson vaccine.

As per the CDC’s recommendations, the new bivalent booster replaces the existing monovalent vaccine booster, therefore that vaccine will no longer be authorized for use as booster doses in people age 12 and up.
