FDA authorizes Pfizer-BioNTech COVID-19 Vaccine booster dose for certain populations

It is NOT recommended to combine vaccines


The Pfizer booster can be administered 6 months after the second dose. At this time, combining vaccine types is NOT recommended. (If you received two Moderna vaccines or one J&J vaccine, you should NOT receive the Pfizer booster).

Those who qualify for the booster include:

  • Adults who are 65+
  • Adults who reside in a long-term care facility regardless of age
  • Adults over 50+ with underlying medical conditions
  • Adults 18+ with underlying medical conditions based on individual risk
  • Adults 18+ who are at an increased exposure to COVID due to employment (This includes healthcare workers, jail staff, daycare staff, school staff, and grocery store workers)

 Additionally, a distinction was made between "additional doses" and "booster doses". 

  • A booster refers to a dose given to those who had built enough protection after the first two doses, but protection has waned over time. 
  • An additional dose is for someone who didn't get enough protection after the first two doses, such as the severely immunocompromised.

Information regarding booster doses for Moderna and Johnson & Johnson Vaccines will continue to be researched.
