Booster Doses  

COVID-19 boosters help broaden and strengthen protection against COVID-19 and its variants. 

The Pfizer COVID-19 booster dose is authorized and recommended for adolescents aged 12 and older administered at least 5 months post their initial Pfizer vaccination series. Adults are recommended to receive a booster dose at least 5 months after receiving the Pfizer or Moderna series and 2 months after for the Johnson and Johnson series.

New CDC guidance allows adults 18+ to choose which type of vaccine booster they receive, allowing for mixing and matching of vaccines, subject to that vaccine’s timing and eligibility recommendations for booster doses. 

Additional Booster Doses  

People over the age of 50 and certain immunocompromised individuals who received an initial booster dose at least 4 months ago are now eligible for another mRNA booster to increase their protection against severe disease from COVID-19. Adults who received a primary vaccine and booster dose of Johnson & Johnson’s COVID-19 vaccine at least 4 months ago may now receive an additional booster dose using an mRNA COVID-19 vaccine. For more information.

  • People ages 12 years and older who are moderately or severely immunocompromised may choose to receive a second booster dose using an mRNA COVID-19 vaccine at least 4 months after the first booster dose.
  • Adults ages 50 years and older who are not moderately or severely immunocompromised may choose to receive a second booster dose using an mRNA COVID-19 vaccine at least 4 months after the first booster dose.
  • People ages 18–49 years who are not moderately or severely immunocompromised and who received Johnson & Johnson COVID-19 Vaccine as both their primary series dose and booster dose may receive a second booster dose using an mRNA COVID-19 vaccine at least 4 months after the first Janssen booster dose.
