Counties with the highest COVID-19 vaccination rate in Connecticut
As has been true throughout America’s COVID-19 history, every state—and every county threin—has its own COVID-19 story, driven by local policies and behaviors. The United States as of April 20 had reached 568,439 COVID-19-related deaths and more than 31.8 million COVID-19 cases, according to Johns Hopkins University. Amid the grim numbers come two bright spots: As of Feb. 2, more Americans had been vaccinated for COVID-19 than had been infected; and since then, rolling averages for case counts and deaths have been on the decline.
