Get your COVID-19 booster

The new two-strain vaccine is available for all those aged 12 years and older.

What to do

New COVID-19 boosters

September 2, 2022: The U.S. Food and Drug Administration (FDA) has authorized Pfizer and Moderna bivalent vaccine (“two strain”) boosters. The new boosters are more effective against the current COVID-19 variants. Here is what you need to know:


  • Health care providers and pharmacies will administer the majority of the new boosters. Those with health insurance are encouraged to reach out to their health care providers for the booster.
  • You are eligible for the new booster if you’ve completed the primary two dose series, whether or not you’ve had prior boosters, as long as it has been at least two months after your most recent dose.
  • The new vaccine is more effective against current COVID-19 variants. The original (Pfizer and Moderna) vaccine will no longer be used as boosters for those 12 and up, but are still safe, effective, and fully approved for someone’s primary series dose.
  • COVID-19 vaccine, including the new booster, are safe to give at the same time as flu vaccine. The shots should be given at least one inch apart on the same limb, or on separate limbs.

To get your booster, go to your doctor or nearby pharmacy or vaccine site. Many sites take drop-ins.

Boosters are free and key to keeping San Francisco safe.

  • The Pfizer-BioNTech COVID-19 bivalent “two-strain” vaccine is available for people aged 12 years and older.
