Counties with the highest COVID-19 vaccination rate in California
Counties with the highest COVID-19 vaccination rate in California
The vaccine deployment in December 2020 signaled a turning point in the COVID-19 pandemic. 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 Oct. 28 reached over 1 million COVID-19-related deaths and 97.4 million COVID-19 cases, according to Johns Hopkins University. Currently, 68.4% of the population is fully vaccinated, and 7.3% of people have received the most recent bivalent booster dose.
