  • Public health agencies across the Bay Area urge everyone eligible to get vaccinated and, if eligible, get a booster shot right away to protect against the rapidly spreading Omicron variant.

    Widely available via appointment or drop-in sites, boosters maintain the power of vaccines to strongly protect against severe illness and death from COVID-19. Everyone should get one when eligible, but particularly those over 50 or those with significant underlying health conditions.

    Get a booster if you are at least 16 years old and:

    ► 6 months have passed since your second dose of Pfizer (for 16+)
    ► 6 months have passed since your second dose of Moderna (for 18+)
    ► 2 months have passed since your Johnson & Johnson dose (for 18+)

    Public health officials in Alameda, Contra Costa, Marin, Monterey, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano and Sonoma counties as well as the City of Berkeley encourage anyone eligible who needs a booster dose to get one as soon as possible.

    To find a booster shot appointment or drop-in booster location in San Mateo County, please go to or to MyTurn.

    Currently, just 34% of eligible San Mateo County residents have received a booster.

    While there have been no confirmed cases of the Omicron variant reported to San Mateo County Health, evidence of this variant has been detected in county wastewater samples.

    Many more cases of Omicron are expected to be reported in the coming days and weeks, and, based on the exponential growth in cases being seen in Europe, there is a significant risk of exponential growth in COVID-19 cases in our region. The United Kingdom currently has more COVID-19 cases than at any time during the 2-year pandemic. Other highly vaccinated countries that mirror the Bay Area’s high vaccination rates, such as Denmark and Norway, are predicting Omicron will become the dominant variant in a matter of days.

    Evidence suggests that Omicron spreads more rapidly than other variants, and more is being learned every day. Although some evidence suggests that a lower percentage of people infected with Omicron may be hospitalized and die, if a surge causes many thousands of new cases per day, even a small percentage of that total entering our hospitals will overwhelm healthcare delivery systems.

    “A booster dose as soon as you are eligible is essential to protect yourself and your family from COVID-19,” said Dr. Scott Morrow, San Mateo County health officer. “Even if you were fully vaccinated earlier this year, a booster will increase your protection against the Omicron variant.”

    In addition to vaccinations and boosters, masking, testing, ventilation, and distancing remain an effective multi-layered defense against COVID-19. As the holiday season is upon us, people should stay mindful of risks and take steps to decrease them.

    If people must travel or gather for the holidays:

    ► Anyone who develops symptoms of COVID-19 should isolate themselves and get tested as soon as possible.
    ► Get tested before gathering or traveling, upon return, and again 3-5 days later.
    ► Have everyone ages 5+ get their COVID-19 vaccine and booster if eligible.
    ► Take advantage of quick and easy home test kits available in pharmacies and stores.
    ► Wear a mask indoors and in crowded settings.
    ► Keep group gatherings small. Gather with close family units.
    ► Outside gatherings are safer than indoor gatherings.
    ► Be particularly cautious around elderly or immunocompromised individuals and consider COVID-19 testing before such interactions.

    Parents of very young children and those who have not been vaccinated should make sure to take all advised precautions. Avoid large gatherings. Always wear a mask in indoor public settings (unless under age 2).

    Vaccinations are available at no cost to the public, insurance is not required, and there are no immigration requirements.

    Boosters are available through MyTurn and from health care providers and pharmacies. San Mateo County’s drive-through booster clinic at the Event Center will close after December 18 and re-open on January 4as a walk-through clinic in a different building at the site. Other County-operated community clinics offering boosters, as well as first and second doses, may be found in MyTurn and here:
