Claim about “defective” COVID-19 vaccines resurfaces

A vaccine opponent group shared a video news segment on social media that is raising concerns about COVID-19 vaccines. The video claims that in 2021, a group of 18 people in Connecticut experienced cardiac issues due to a “defective” batch of Pfizer’s COVID-19 vaccine. In comments on the video, social media users are expressing concerns about adverse reactions to COVID-19 vaccines.

Risk level: Medium

Recommendation: Online conversations about this recirculating news clip promote false claims about COVID-19 vaccine safety and may discourage patients in the Northeast from getting the updated COVID-19 vaccine. It is recommended doctors in the Northeast be prepared to answer questions about the safety and efficacy of COVID-19 vaccines. Talking points may emphasize that COVID-19 vaccines have been rigorously tested and monitored over three years and have been determined to be safe. Adverse reactions to COVID-19 vaccines—including cases of post-vaccine myocarditis—are extremely rare. A COVID-19 infection is more likely to cause myocarditis than a COVID-19 vaccine, which is why staying up to date on COVID-19 vaccines is a safe way to protect against myocarditis.
