Four team members at Advocate Condell Medical Center in Libertyville, Illinois, experienced "tingling and elevated heart rate," according to a press release.
"These four team members represent fewer than 0.15% of the approximately 3,000 who have so far received vaccinations across Advocate Aurora Health. At this time, we can share three team members are home and doing well, and one is receiving additional treatment," Advocate Aurora Health said in a statement.
They explained that reactions are an expected side effect of vaccination, and they still encourage others to get vaccinated to put an end to the coronavirus pandemic.
"These vaccines are very immunogenic, meaning they stimulate a strong immune response, and so the likelihood is that if you're having symptoms after a vaccine, that your body's responding incredibly well to the vaccine," said Dr. Grace Lee, a pediatric infectious disease physician at Stanford, told KGO-TV for a Dec. 15 report.
