Vaccinations for San Mateo County residents are reported to SMC Health via the California Immunization Registry (CAIR2). COVID-19 vaccine administration data are reported as timely, accurately, and completely as data become available. Previous data will change as new and updated data are received. This dashboard provides a summary of vaccinations administered to San Mateo County residents only and does not include vaccinations provided by federal organizations such as the Department of Veterans Affairs (VA).

This dashboard draws on newly released demographic projections from the California Department of Finance, which provides more accurate and detailed population estimates by race/ethnicity and gender, and for all age categories.

The demographic information here cannot be cross mapped to location-related dashboards, showing vaccine reach in cities, ZIP codes, and census tracts, which draw on data from the American Community Survey (US Census Bureau).
