RALEIGH, N.C. (WNCN) – Four people were taken to the hospital after suffering adverse reactions to the Johnson & Johnson COVID-19 vaccine during a clinic at PNC Arena.

According to Wake County health officials, 18 people in total were evaluated. The remaining 14 had “minor reactions” and were treated on site.

Wake County halted administering COVID-19 vaccines at the PNC Arena on Thursday following the report.

County health officials are consulting with the North Carolina Department of Health and Human Services before proceeding.

Wake County said 2,300 doses of the Johnson & Johnson vaccine were administered Thursday at the PNC Arena clinic.

“Currently the Centers for Disease Control and Prevention are analyzing the vaccine lot and expect to issue guidance within the next two hours,” Wake County said. “Wake County is committed to providing safe community clinics, and it’s thanks to the 15-minute observation period adhered to at these sites that staff was able to provide immediate care.”

Wake County said less than two hours worth of appointments were left when the clinic was closed. Those with appointments were offered the Pfizer vaccine or the ability to reschedule once the evaluation is completed.

A short time later, UNC Health announced it paused its distribution of the J&J vaccine after a few patients felt faint and light-headed.

Duke Health released the following statement, saying it didn’t plan to stop using the J&J vaccine:

“Duke Health received Janssen (J&J) vaccine from the same lot number identified in the Wake County vaccine clinic, but the shipment was sent directly to Duke through no intermediaries. No patients at Duke have experienced serious incidents. Minor side effects from the vaccine have been consistent with those reported by the manufacturer prior to authorization and remain within expected rates. As a result, we do not plan to pause vaccinations at this time and will continue to follow all vaccination policies and guidance from the CDC.”

A mass vaccination site in Colorado closed early on Wednesday afternoon after people started having adverse reactions to the Johnson & Johnson shot.

Centura Health said Wednesday night that 11 patients experienced the reactions after receiving an injection at Dick’s Sporting Goods Park in Commerce City.

Medical staff on site determined two individuals required additional observation and out of an abundance of caution, they were transported to nearby hospitals.

Earlier, the company told Nexstar station KDVR that 0.8 percent of patients — or 13 people out of an estimated 1,700 — who received the vaccine experienced adverse reactions.

Johnson & Johnson sent the following statement to CBS:

There is no greater priority than the safety and well-being of the people we serve. When we receive reports of adverse events in individuals receiving our medicines and vaccines, we collect necessary information and carefully assess the events. Reports about individuals receiving our COVID-19 vaccine and our assessment of those reports are shared with the U.S. Food and Drug Administration and other appropriate health authorities. This is part of the established process to inform health authorities’ comprehensive surveillance programs that monitor the overall safety of medicines, as well the vaccines authorized for use against this pandemic.
