Who should get a COVID-19 booster shot?

I am immunocompromised. When should I receive a booster vaccine dose?

I tested positive for COVID-19. When can I get a booster dose?

Can I mix and match COVID-19 vaccine and booster shot brands?
  • Individuals aged 5-17 can only receive the Pfizer-BioNTech booster. 
  • Individuals aged 18 and older may choose which vaccine they receive as a booster dose. 

Recommendations by the Centers for Disease Control and Prevention now allow for mix-and-match dosing for booster shots.

Please refer to this CDC chart of information about all three COVID-19 boosters.

How can I schedule a booster shot?

You can book an appointment for the vaccine at one of our vaccination clinic sites by calling 650-498-9000 or via MyHealth.

What is the difference between a third or fourth dose of the COVID-19 vaccine and a booster?

“Additional doses” are different than a “booster dose.” A booster is an added dose of a vaccine that is given to someone with a healthy immune system who built enough protection after being fully vaccinated. If that protection gradually decreases, a booster can help sustain it. Third or fourth doses are provided to individuals with compromised immune systems for whom the original vaccine dose was not sufficient to achieve protection from the virus. For more information on new CDC guidance on COVID-19 vaccine additional doses for immunocompromised people, click here.

Can people receive flu shots and booster shots at the same time?

Yes, the COVID-19 vaccine and flu vaccine may be given at the same time.

What if I want to receive J&J vaccine regardless of the CDC recommendations?

How is the new booster dose different from the original booster?

I already have an appointment scheduled for a COVID-19 booster, should I wait for the new booster?

What if I have not had a booster dose before?
