The U.S. FDA has expanded emergency use authorization (EUA) for the Pfizer/BioNTech and Moderna COVID-19 vaccines. They can now be used to administer a booster dose to all U.S. adults who have completed primary vaccination with any FDA-authorized or approved COVID-19 vaccine.
- Adults who received the Pfizer/BioNTech or Moderna vaccine for primary vaccination can receive a booster dose of either product at least six months after completing primary vaccination.
- Adults who received the Janssen (Johnson & Johnson) vaccine for primary vaccination can receive a Pfizer/BioNTech or Moderna booster at least two months after receiving the Janssen vaccine.
- Under the EUA, individuals do not have to receive the same brand of vaccine for their booster dose as they received for their primary vaccination series.
