"Nearly 92% of cases and 94% of deaths reported since May 6 have been in people who were not fully vaccinated," said Catie Armstrong, press assistant for the state Department of Health and Human Services. "This is consistent with data from other states showing that current increases are being driven almost entirely by infections in people who are not vaccinated."
In North Carolina, state data shows almost 7,300 potential breakthrough cases since the start of the pandemic, including 383 hospitalizations and 66 deaths as of July 22, according to Armstrong. "
Those numbers are preliminary, she said, and could change".
