A North Carolina mass vaccination site paused operations Thursday afternoon after 18 people suffered serious side effects.
The Raleigh clinic was using the Johnson & Johnson vaccine and administered 2,300 shots Thursday, site operator Wake County said in a press release. The reactions occurred at PNC Arena, home of the NHL’s Carolina Hurricanes, which opened as a vaccine site in February.
The symptoms were “consistent with known common side effects,” the county said. In clinical trials, the most common side effects of the Johnson & Johnson vaccine were headaches and fatigue, followed by muscle aches, nausea and fever.
Of the 18 people, 14 were treated onsite, while four were sent to a local hospital, the county said.
