American Heart Association Study Shows Link Between Covid Vaccines and Heart Inflammation
New research in pre-print publication at the American Heart Association’s journal Circulation shows a link between free spike antigens produced by the mRNA Covid shots and a form of heart inflammation known as myocarditis.
Harvard Medical School researchers examined 16 adolescents and young adults hospitalized at Massachusetts General Hospital or Boston Children’s with post-vaccination myocarditis from January 2021-February 2022. The subjects had “markedly elevated levels of full-length spike protein” in their blood, “unbounded by antibodies.”
The medical researchers affiliated with the hospitals, however, did not find free-floating spike antigens in the 45 “healthy, asymptomatic, age-matched vaccinated control subjects,” despite “essentially indistinguishable” antibody profiling and T-cell responses between the groups.
The medical study’s findings isolated the free spike antigens in the young subjects who developed post-shot heart inflammation.
“Immunoprofiling of vaccinated adolescents and young adults revealed that the mRNA vaccine–induced immune responses did not differ between individuals who developed myocarditis and individuals who did not,” the researchers note. “However, free spike antigen was detected in the blood of adolescents and young adults who developed post-mRNA vaccine myocarditis, advancing insight into its potential underlying cause.”
The study establishes further linkage between the mRNA shots and an increased risk of myocarditis in young people by providing a potential biomedical causal mechanism.
In October, Florida’s State Health Officer & Surgeon General Joseph A. Ladapo, M.D., issued guidance that recommended against mRNA shots being given to healthy adults between the ages of 18 and 40.
“The Florida Department of Health (Department) conducted an analysis through a self-controlled case series, which is a technique originally developed to evaluate vaccine safety,” Ladapo announced by press release.
