Get your booster

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

Who

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.

When

Get your booster based on when you were fully vaccinated

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

Where

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.
