Since Thursday, four team members at Advocate Condell Medical Center in Libertyville experienced reactions shortly after receiving the Pfizer COVID-19 vaccination. Their symptoms included tingling and elevated heartrates, the hospital said in a statement.

The hospital also noted that the four team members represent fewer than 0.15% of the approximately 3,000 who have so far received vaccinations across Advocate Aurora Health.

Three of the team members are now home and doing well, the hospital said. One employee is receiving additional treatment.
