COVID-19 Vaccination Program

Overview This Week in San Mateo County Health

Updated, Bivalent Boosters

The updated COVID-19 boosters, which are effective against both the original strain of the virus and the Omicron variants, have been approved for use in California.

Updated boosters are available from primary health care providers, such as Kaiser and Sutter, as well as from pharmacies such as Walgreens, CVS, and others. Vaccines are available with or without advance appointments on MyTurn, though appointments are recommended.

Eligibility for Updated Boosters

  • Moderna Bivalent Booster is authorized and recommended for those 6 years and older.
  • Pfizer Bivalent Booster is authorized and recommended for those 5 years and older.
  • People cannot get a bivalent booster without first completing at least a primary series. 
  • The bivalent booster recommendation replaces previous booster recommendations.


Boosters should be administered at least 2 months after completion of the primary series or the most recent booster dose of the original COVID-19 vaccine.

Equity in Vaccine Distribution

San Mateo County and the state of California have made equity a key priority of local vaccine distribution.

Our communities of color, low-income communities, older adults, and other impacted populations face many barriers to vaccine acceptance and access. We are currently involved in a community engagement effort to learn from leaders closest to our most impacted communities. For more information about acknowledging the impact of medical distrust, click here. We look forward to hearing from community leaders about their needs and concerns so we can respond, plan accordingly, and adjust as we learn.
