The CDC has approved “mix and match” booster doses for those who are receiving a booster dose after their primary series. This means that a person can receive a booster of a COVID-19 vaccine that is different than the COVID-19 vaccine they received for their primary series. For primary and booster vaccination, people should receive an age-appropriate mRNA vaccine (Pfizer or Moderna). The Johnson & Johnson vaccine is authorized for anyone age 18 and older if no other approved vaccine is available. Bring your COVID-19 Vaccination Record Card to your appointment.

See additional recommendations for people who are moderately to severely immunocompromised. A second booster dose is recommended for certain people at increased risk of severe disease.
