A hospital in a suburb of Chicago has temporarily stopped its Covid-19 vaccination program for frontline personnel after four workers experienced reactions.
Advocate Aurora Health said in a statement obtained by CNN affiliate WLS that as of Friday, four workers at Advocate Condell Medical Center, in Libertyville, Illinois, have experienced tingling and elevated heartrate symptoms shortly after receiving the vaccine.
"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 the statement.
The health care company noted these four workers represent "fewer than 0.15% of the approximately 3,000 who have so far received vaccinations across Advocate Aurora Health."
The company said the pause "will allow us time to better understand what may have caused these reactions," adding vaccination will continue in eight other locations across Illinois and Wisconsin.
