About 500 cases of myocarditis have been reported in young people after vaccination with mRNA vaccines in the United States, although the link between vaccines and myocarditis has not been established, Fox News reports, citing the advisory committee of the American medical regulator CDC.
The Committee concluded that the benefits of the vaccine still outweighed the possible risks.
“The data currently available suggest a possible association of myocarditis with mRNA vaccination in adolescents and young adults,” the Vaccine Safety Technical Working Group (VaST) said in its conclusion. Tom Shimabukuro, deputy director of the CDC’s Office of Immunization Safety, noted that there were 484 preliminary reports of myocarditis and pericarditis in individuals less than 30 years of age at 27 million doses. Of this number, 309 people were hospitalized, almost all of them were discharged immediately after the examination, and almost 80% have already got rid of symptoms. 9 people remain in the hospital.
“It appears that mRNA vaccines may be a new trigger for myocarditis,” said Matthew Oster of the CDC’s working group on vaccines.
Myocarditis is an inflammatory disease of the myocardium; pericarditis is an inflammatory lesion of the serous membrane of the heart. Two mRNA vaccines have been approved for use in the United States. Pfizer’s vaccine is approved for children over 12, and Moderna is approved for those over 16.
