US: A new study by the Journal of the American Medical Association (JAMA) revealed the development of myocarditis and pericarditis after mRNA COVID-19 vaccination, The study was based on Vaccine Adverse Event Reporting System (VAERS) data, for 192, 405 ,448 people over the age of 12 years old who received the Pfizer or Moderna vaccines between December 2020 and August 2021. The rates of myocarditis cases were highest after the second vaccination dose in adolescent males aged 12 to 15 years. Males comprised 82% of the myocarditis cases for whom sex was reported. The JAMA researchers warned that “this risk should be considered in the context of the benefits of COVID-19 vaccination.”

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.

The idea that these are “unintended” consequences doesn’t fly. Dr. David Martin has said that these shots are bioweapons, no doubt. And the public just keeps going along with Mengele. Criminals deserve to be treated as criminals. See Attny General letter at

They’ll probably have some establishment stooge medical doctor go on CNN to reassure everyone that myocarditis and pericarditis are no big deal and that having these conditions just means that the “vaccines” are working. I also think it would be a nice touch to have Fauci, Gates, Trump, and Biden do a couple of photo ops with a few of the permanently damaged children in the hospital. They could each take turns holding the kid’s hand and spouting some platitudes about how these kids have sacrificed their own health for the good of all.
