With Vossoiughian’s confirmation that she suffered pericarditis and myocarditis, there was widespread speculation on social media that it may have been caused by a COVID-19 vaccine or booster. The MSNBC host did not make mention of COVID-19 or vaccines during her segment, and she said her doctors blamed it on the common cold virus.
Both pericarditis and myocarditis are considered side effects of mRNA vaccines manufactured by Pfizer and Moderna, according to the Food and Drug Administration and Centers for Disease Control and Prevention.
But, according to Johns Hopkins University, while rare, myocarditis can be caused “by an infection in the body,” including the common cold, influenza, and COVID-19. Bacterial, fungal, and parasitic infections can also lead to myocardial inflammation.
