EYEWITNESS NEWS (WBRE/WYOU) — 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 May 6 reached 997,023 COVID-19-related deaths and nearly 81.7 million COVID-19 cases, according to Johns Hopkins University. Currently, 66.3% of the population is fully vaccinated, and 45.9% of vaccinated people have received booster doses.

Stacker compiled a list of the counties with the highest COVID-19 vaccination rates in Pennsylvania using data from the U.S. Department of Health & Human Services and Covid Act Now
