Updated, Bivalent Boosters
San Mateo County Health offers updated, bivalent boosters, which are effective against both the original strain of the virus and the Omicron variants, at its community clinics. Advance appointments are available on MyTurn, though appointments are not required.
Updated boosters are also available from primary health care providers, such as Kaiser and Sutter, as well as from pharmacies such as Walgreens, CVS, and others.
Eligibility for Updated Boosters
- Moderna Bivalent Booster is authorized and recommended for those 18 years and older.
- Pfizer Bivalent Booster is authorized and recommended for those 12 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 for people 12 years and older.
- 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.
Moderna Supplies Arriving More Slowly than Pfizer
While County Health’s clinics offer updated boosters from Pfizer (for 12+) and Moderna (for 18+), supplies of Moderna have been slower to arrive. Individuals who have booked appointments for Moderna may be offered Pfizer if supplies are low. The Centers for Disease Control and Prevention and the California Department of Public Health advise eligible individuals to get either booster, regardless of which vaccine brand they have already received.
County Health recommends that residents stay up to date with COVID-19 vaccines, get tested if symptomatic, and connect with a doctor or Test-to-Treat offering if infected. Those at high risk for severe illness should consider taking additional precautions (such as avoiding crowded indoor activities with poor ventilation).
The current risk of getting monkeypox (MPX) in the general public is very low.
Guidance on MPX, current case rates, and vaccine information is available here. San Mateo County residents who meet eligibility guidelines can schedule a vaccination appointment on the My Turn website. If you meet the eligibility guidelines but are unable to schedule an appointment, sign up to be notified about upcoming MPX vaccination opportunities using the County Health’s vaccination request form.
