Get your booster

Open to everyone 12 and older

Boosters are free and key to keeping San Francisco safe.

Go to your doctor or nearby pharmacy or vaccine site. Many sites take drop-ins, but people with appointments have priority.


Boosters are recommended for

  • Anyone 12 or older
  • Fully vaccinated with Pfizer, Moderna, or Johnson & Johnson

12 to 17 year olds can only get a Pfizer booster.


Get your booster based on when you were fully vaccinated

  • Pfizer and Moderna, after 5 months
  • Johnson and Johnson, after 2 months


Though many sites take drop-ins, people with appointments have priority. Vaccines and boosters are in high demand.

Mix or match

If you got the J&J vaccine

  • For most situations you should get the Pfizer or Moderna booster
  • This is recommended by both the Centers for Disease Control (CDC) and the California Department of Public Health (CDPH)

If you got the Pfizer or Moderna vaccine

  • You can mix your booster so you get a different brand of mRNA vaccine
  • Or you can match it and keep the brand the same

Ask your doctor or the healthcare professional giving you your booster which is best for you.
