Vaccine boosters

CDC advises people should receive a booster dose from a COVID-19 vaccine provider if they are age 12 and older and:

  • it has been 5 months since their last dose of Pfizer or Moderna vaccine or
  • it has been 2 months since they received a Johnson & Johnson vaccine

You can choose any vaccine as a booster dose. It does not have to be the same vaccine as your original. Teens ages 12 to 17 should only receive the Pfizer vaccine. Read the full CDC guidance.
