COVID-19 Booster Vaccination among County Residents by Census Tract

Percentage of county residents who are boosted with COVID-19 vaccines by census tract of residence. Source: California Immunization Registry. Note: Doses administered are categorized as a booster dose if the dose is a third dose administered six or more months after a second dose of Pfizer or Moderna or if the dose is a second dose administered two or more months after a dose of Janssen/Johnson & Johnson. Percent of residents who are boosted with COVID-19 vaccines and population age 12 years and older is based in part on estimates of the number of people residing in the census tract from a population-based survey sample, which is subject to error. As a result, percent vaccinated may be over- or under-estimated. For this reason, the displayed percent of residents vaccinated in a census tract is capped at 95%.

COVID-19 vaccination among county residents by census tract is updated every Tuesday. This table was updated for the last time on January 24, 2023.
