Where does Contra Costa fall in state vaccination rankings?

By the end of May 2021, 40% of the U.S. population was fully vaccinated. But as vaccination rates lagged over the summer, new surges of COVID-19 came, including Delta in the summer of 2021, and now the Omicron variant, which comprises the majority of cases in the U.S.

The United States as of Jun. 24 reached over 1 million COVID-19-related deaths and nearly 86.8 million COVID-19 cases, according to Johns Hopkins University. Currently, 66.9% of the population is fully vaccinated, and 47.3% of vaccinated people have received booster doses.

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 Jun. 23, 2022. Due to inconsistencies in reporting, some counties do not have vaccination data available.
