The 2 mRNA vaccines administered worldwide from Pfizer and Moderna could bring increased risks of myocarditis and pericarditis. Most cases occurred with Pfizer’s vaccine, called Comirnaty.
Approximately 177 + million doses of Comirnaty had been given in the European Medicines Agency compared to 20 million doses of Moderna’s Spikevax vaccine.
Meanwhile, there have been less than 300 confirmed cases of myocarditis or pericarditis among over 150 million fully vaccinated people in the U.S. This would still be less than your odds of being killed by a cow, if you believe the one in 300,000 number in the photo accompanying the following tweet:
Earlier, Europe’s drug regulator has found a possible link between very rare heart inflammation and COVID-19 vaccines from Pfizer-BioNTech (PFE.N), (22UAy.DE) and Moderna (MRNA.O), it said on Friday, stressing that the benefits of the shots outweighed any risks.
What are the symptoms of myocarditis or pericarditis related to mRNA Vaccines?
In addition to chest pain, other possible symptoms of myocarditis or pericarditis include shortness of breath or unusual heart rhythms. “If you have any such symptoms after getting the Covid-19 vaccine notify your doctor,” Several Medical Experts advise. “It may not be the result of the vaccine and other things may be going on,” so it is important to “be aware of one’s self” and to have your doctor to assess your situation.
Currently, the FDA warnings cover only the Pfizer/BioNTech and Moderna Covid-19 mRNA vaccines. This doesn’t necessarily mean that such concerns are unique to the mRNA vaccines. Wong emphasized that by comparison, “there have been relatively fewer doses of the Johnson & Johnson vaccine administered.”
