COVID-19 Vaccines, New Infections Are Pushing SC Toward Herd Immunity by Fall, Experts Say
One way or another, millions more South Carolinians need to acquire immunity from the coronavirus before the disease is at bay. The goal is herd immunity, and it is a moving target. Jane Kelly, assistant state epidemiologist with the South Carolina Department of Health and Environmental Control, said last week that community spread of the disease should stop once 70 percent of the population has acquired immunity. That’s herd immunity. But, she said, public health experts must set the bar higher — up to 85 percent — in places where infections are rampant.
