Marin County 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). San Quentin Inmates' vaccination rates are not included in this dashboard and are available at The dashboard is updated weekly, on Fridays. ** As DOF population estimates may not be precise, the proportion of vaccinated people in any group will be displayed up to, but not higher than 98%. 

Marin County COVID-19 Outcomes by Vaccination Status

Due to the small estimated number of unvaccinated individuals in Marin County and shifts in testing behavior with an increased reliance on home testing, which are not mandated to be reported, we will no longer be displaying COVID-19 Outcomes by Vaccination Status using Marin County data. Instead, we direct visitors to State and National data that show comparisons of COVID-19 outcomes for vaccinated and unvaccinated people using much larger populations, which increases the reliability of the estimates. To view these resources, visit the CDPH COVID Data Tracker webpage and the CDC COVID Data Tracker webpage. Both dashboards are updated monthly.

COVID-19 Vaccination and Case Rates by Geography

Mapping vaccines distributed by geographic regions helps us view COVID-19 vaccine coverage in the community on a more granular level. The map below shows the number and proportion of residents in each census tract who have: 1) received at least one dose of a COVID-19 vaccine; 2) completed their primary vaccine series (2 doses for Pfizer and Moderna and 1 dose for Johnson and Johnson); or 3) completed their primary vaccine series and received at least one booster dose. The labeled numbers on each census tract are the percentage of residents who completed their primary vaccine series and who have received at least one booster dose. This map is interactive, click on each jurisdiction to view the name of the community/city, the total population for that area, the total population, vaccine metrics, and cumulative and 14-day COVID-19 case information. This map is based on the residence provided by individuals receiving a COVID-19 vaccine. If the map fails to load click here. **
