The claim
The Moderna and Pfizer Covid-19 vaccines cause heart damage.
PeakMetrics research summary
Based on related reporting. This does not summarize the original publisher’s reasoning.
Related reporting describes myocarditis as a recognized, rare risk associated with COVID-19 vaccination. It also says the FDA required Pfizer and Moderna to update their warning labels to reflect the increased risk; the excerpts do not establish that the vaccines cause heart damage generally.[S3][S4]
