FDA to add warning on mRNA COVID-19 vaccines about rare heart-related side effect

Dr. Pranav Patel, chief of cardiology and an interventional cardiologist with UCI Health, says myocarditis and pericarditis can occur naturally due to viral and other infections. “But the rate seen after [the mRNA] vaccines is slightly higher than would be expected for younger individuals,” he said. “This is what caused the CDC to look more closely into this.” … Patel says that because the chance of heart inflammation is extremely low, the CDC is still recommending that all people 12 years old and older receive a COVID-19 vaccine.
