Vaccination rates across Kentucky’s 120 counties vary from as low as 23 percent to as high as 63 percent, according to data from the Centers for Disease Control and Prevention.

Health officials have advocated for vaccinations to help stop the spread of COVID-19 in Kentucky, especially after the highly transmissible Delta variant became the dominant version of coronavirus in the commonwealth. New case counts in Kentucky are higher than they’ve been in several months.

Over the past several weeks, Kentucky’s rate of cases per 100,000 people has reached the “red zone” in all 120 counties. The state measures average cases per 100,000 residents to determine incidence rate, which is used to measure severity of the virus’ spread.
