Though rare, Moderna Covid vaccine recipients have higher risk of heart inflammation than Pfizer

Spencer Kimball - Saturday

The overwhelming majority of people who had myocarditis after Covid vaccination fully recovered and most reported no impact on their quality of life, according to a CDC survey of cardiologists and other health-care providers.

 

 There were no known deaths from myocarditis following vaccination in the group, according to the data. 

People face a much higher risk of developing myocarditis from Covid infection than the vaccines, according to the Department of Health and Human Services.

 The risk of myocarditis from Covid is 100 times higher than developing the condition after vaccination, according to a recent paper in Nature Reviews Cardiology. Depending on the study, the risk of dying from Covid associated myocarditis is between 20% and 70%, while the risk of death from myocarditis due to vaccination is less than 1%, according to the paper.

Whereas with myocarditis due to Covid, it’s more severe, it lasts longer, and the mortality rate can be significant,” said Romero, who serves as the secretary of health in Arkansas.

However, the European Union’s top drug agency said the benefit of both vaccines outweighs the risks because myocarditis as a side effect is rare.
