Covid-19 Vaccines Carry Low Risk of Heart Conditions, Studies Find https://www.wsj.com/articles/covid-19-vaccines-carry-low-risk-of-heart-conditions-studies-find-11649716211
The risk of developing inflammatory heart conditions after Covid-19 vaccination is relatively low, two large studies found, especially when compared with the heart-related risks from Covid-19 disease itself and from vaccines against other diseases.
One study, an analysis of 22 previous studies, found that the risk of the conditions including myocarditis in people who received a Covid-19 vaccine wasn’t significantly different from that for non-Covid-19 vaccines such as those against flu, polio and measles. And the heart risk associated with Covid-19 shots was lower than the risk after smallpox vaccination. The results of the analysis, which included data on the effects of more than 400 million doses of various vaccines, were published online Monday by The Lancet Respiratory Medicine.
Another analysis published April 1 by the Centers for Disease Control and Prevention found that the risk of cardiac complications including myocarditis, an inflammation of heart muscle, was higher in people after Covid-19 infections than after receiving a Covid-19 vaccine.
