Marin County COVID-19 Vaccination Data
COVID-19 Vaccination Rates
This dashboard shows the number of vaccinations received by Marin residents. Immunization data is pulled from the California Immunization Registry (CAIR), and population data is based on the California Department of Finance population estimates (2021). Because population estimates may not be precise, the proportion of vaccinated people in any group will be displayed up to, but not higher than 98%. San Quentin Inmates' vaccinations are displayed separately at www.cdcr.ca.gov/covid19/population-status-tracking/.
