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. It 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 vaccination was 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.
98% of the cases were mRNA and only 3% J&J. While rare, this is also turning up in women, girls, and older people.
Even though ‘rare’, should the ‘vaccine’ be mandated if it can cause heart problems that could stay with the affected person?
From the Abstract:
Key Points
Question What is the risk of myocarditis after mRNA-based COVID-19 vaccination in the US?
Findings In this descriptive study of 1626 cases of myocarditis in a national passive reporting system, the crude reporting rates within 7 days after vaccination exceeded the expected rates across multiple age and sex strata. The rates of myocarditis cases were highest after the second vaccination dose in adolescent males aged 12 to 15 years (70.7 per million doses of the BNT162b2 vaccine), in adolescent males aged 16 to 17 years (105.9 per million doses of the BNT162b2 vaccine), and in young men aged 18 to 24 years (52.4 and 56.3 per million doses of the BNT162b2 vaccine and the mRNA-1273 vaccine, respectively).
Meaning Based on passive surveillance reporting in the US, the risk of myocarditis after receiving mRNA-based COVID-19 vaccines was increased across multiple age and sex strata and was highest after the second vaccination dose in adolescent males and young men.
