herd immunity

  • As COVID-19 cases are declining in Ohio, new research suggests Ohio will not reach herd immunity until November. Health officials announced Monday that nearly 39 percent of the state’s population is fully vaccinated, but many wonder if Ohio will reach the benchmark for herd immunity of at least 70 percent.
