The COVID-19 vaccines are very good at preventing severe disease, but protection can lessen over time. 

A booster shot is an additional shot recommended to give longer lasting protection. Many vaccines need boosters after a period of time. 
Additional doses of vaccine are recommended for people who have certain serious medical conditions and need extra doses to get a good immune response.

Who should get  a COVID-19 booster shot? 

Everyone age 12 and older, including people who are immunocompromised and received a third dose of Pfizer or Moderna, should get a booster dose. You are eligible for a booster shot once it has been:

  • At least 5 months after receiving the second dose of Pfizer or Moderna
  • At least 3 months after receiving the third dose of Pfizer or Moderna if you are immunocompromised
  • At least 2 months after receiving the Johnson & Johnson vaccine

Booster doses for people age 11 and under are not available at this time. 

Who should get  an additional dose? 

For people who are age 5 and up and who are immunocompromised, an additional dose is recommended at least 28 days after the initial series (two doses of Pfizer or Moderna, one dose of Johnson & Johnson). Read more about additional doses for immunocompromised people

Which brand should I get? 

  • 12-17 year olds must get Pfizer. 
  • Ages 18 and up can get any brand, based on availability, however mRNA vaccines (Pfizer and Moderna) are now recommended for most individuals. Johnson & Johnson is an acceptable alternative for individuals who cannot receive an mRNA vaccine, who do not have access to mRNA vaccine, or who otherwise prefer to receive the Johnson & Johnson vaccine.  
  • All are effective. Find out more.
