What to Know: Updated Covid Boosters

The updated booster shots from Pfizer-BioNTech and Moderna target the version of the virus that is currently circulating.

Anyone who has been fully vaccinated is eligible, whether or not they received booster shots, but their last shot must have been at least two months ago.

That means at least two doses of Pfizer, Moderna or Novavax, or one of Johnson & Johnson.
