The vaccine deployment in December 2020 signaled a turning point in the COVID-19 pandemic.

But as vaccination rates lagged, the U.S. saw new COVID-19 surges, including one fueled by the delta coronavirus variant in the summer of 2021, and now the Omicron variant, which comprises the majority of cases in the U.S.

Stacker compiled a list of the counties with highest COVID-19 vaccination rates in California using data from the U.S. Department of Health & Human Services and Covid Act Now. Counties are ranked by the highest vaccination rate as of Jan. 13, 2022. Due to inconsistencies in reporting, some counties do not have vaccination data available. Keep reading to see whether your county ranks among the highest COVID-19 vaccination rates in your state.
