A clip has resurfaced of Robert F. Kennedy Jr. claiming that COVID-19 vaccines cause heart attacks in vaccinated people at five times the rate of unvaccinated people. The clip originally circulated in January.
The persistence of this false claim increases its risk. Debunking messaging may emphasize that COVID-19 vaccination is not associated with an increased heart attack risk—COVID-19 infection is. In fact, in people with previous COVID-19 infections, COVID-19 vaccination may decrease the risk of heart attack, stroke, and other cardiovascular issues. Severe adverse reactions following COVID-19 vaccines are extremely rare.
