Under the newly amended emergency use authorizations, a Moderna booster can be given six months after the first two doses to those 65 years or older and all adults at “high risk of severe COVID-19” or that have a greater risk of exposure due to their place of employment.
In a change from the Moderna and Pfizer shots, the FDA authorized boosters for all adult recipients of the one-shot Johnson & Johnson vaccine, at least two months after the initial dose. Additionally, the FDA will now allow mixing and matching where individuals receive a booster dose from a different vaccine type from their original shot.
