A new study released on Tuesday by the Journal of the American Medical Association (JAMA) revealed the development of myocarditis and pericarditis after mRNA-based COVID-19 vaccination which is highest in adolescent males and young men.
The study was based on the data from VAERS on reported cases of myocarditis that occurred after receiving the Pfizer and Moderna vaccine between December 2020 and August 2021 in 192, 405 ,448 individuals older than 12 years of age in the US. These data were processed by VAERS as of September 30, 2021.
The primary outcome after the vaccination was the occurrence of myocarditis and the secondary outcome was pericarditis.
According to the study, VAERS received 1,991 reports of myocarditis (391 of which also included pericarditis) after receipt of at least 1 dose of mRNA-based COVID-19 vaccine and 684 reports of pericarditis without the presence of myocarditis.
Of the 1991 reports of myocarditis, 1,626 met the CDC’s case definition for probable or confirmed myocarditis.
