Fifty percent of all South Carolinians have received at least one dose of COVID-19 vaccine, state health officials said Thursday. The milestone comes as the state still lags in total vaccinations, trailing all but 11 states as of Thursday, according to federal figures.

And after dropping for months as vaccinations became available, COVID-19 cases are again on the rise in South Carolina as the delta variant works its way through the state, according to the S.C. Department of Health and Environmental Control (DHEC).

With 50% of the state, about 2.15 million people, having received at least one dose of vaccine, 44% of the state is fully vaccinated — at least two weeks out from their final dose of whichever vaccine they received.

“This milestone is encouraging, and we thank everyone who made the decision to get vaccinated. We are especially proud of our senior citizens, ages 65 and up, who account for more than a third of our state’s vaccinations. But we still have a lot of work to do,” said Dr. Edward Simmer, DHEC’s director.

Still, South Carolina lags most other states in terms of total population vaccinated. Just 11 states have vaccination percentages lower than South Carolina’s, according to the federal Centers for Disease Control (CDC). Note: Latest data from CDC appears to be slightly different from what’s provided by the state and could include a delay in reporting.

Cases have jumped in recent weeks, DHEC data shows. After regularly reporting double-digit cases through mid-June, state health officials reported 474 confirmed cases of COVID-19 on Thursday.

DHEC officials noted between early June and mid-July, at least 150 cases came from state residents who attended summer camps. That could be a preview of what’s to come as the school year approaches and students begin interacting in person again, DHEC said.
