The U.S. Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) discovered that compared to the background risk in the general population, the risk of myocarditis is 133 times greater in those who took the mRNA injections from either Pfizer-BioNTech or Moderna.
Researchers from several top universities and hospitals across America contributed to the study, which was published in the Journal of the American Medical Association (JAMA).
Using data from the government-run Vaccine Adverse Event Reporting System (VAERS), the CDC and the FDA identified 1,626 cases of myocarditis, which were cross-checked to ensure the results comply with the CDC's official definition of myocarditis.
Based on this, researchers determined that the most high-risk mRNA jab is the one produced by Pfizer-BioNTech, meaning this one is the most dangerous in terms of potential health effects.
The Pfizer jabs, according to the data provided to VAERS, caused 105.9 cases of myocarditis per million doses after the second injection in the male 16- and 17-year-old age and sex demographic. In the 12-15 age group for males, there were 70.7 cases of myocarditis per million doses following the second shot.
The 18-24 male age group had the highest risk at 52.4 cases per million for Pfizer and 56.3 cases per million for Moderna. The median time to symptom onset was just two days for both jabs.
