Study Explains Post-Covid Vaccine Heart Inflammation 2023
The research found that immune cells and inflammation caused heart inflammation after Covid immunization, not antibodies. Myocarditis, a small cardiac inflammation that might scar, usually resolves within days. Males who received SARS-CoV-2 mRNA vaccinations had a higher rate of myocarditis.
After a second vaccination dosage, 22 to 36 per 100,000 men aged 12 to 17 had myocarditis within 21 days, according to the CDC. Yale University researchers examined immune system responses in uncommon vaccinated myocarditis patients.
mRNA vaccinees increased myocarditis in men, according to the study.
They found the heart inflammatory immunological signature. “The immune systems of these individuals get a little too revved up and over-produce cytokine and cellular responses,” said Yale immunobiology assistant professor Carrie Lucas.
The findings, published in Science Immunology, rule out some of the possible reasons of heart inflammation and offer approaches to prevent an uncommon adverse effect of immunization.
Immunization intervals of four to eight weeks have been shown to reduce myocarditis risk.
Lucas stated that the CDC found that unvaccinated Covid-19 patients have a far higher risk of myocarditis than vaccinated patients. Vaccination is the greatest defense against COVID-19.
“I hope this new knowledge will enable further optimising mRNA vaccines, which, in addition to offering clear health benefits during the pandemic, have tremendous potential to save lives across numerous future applications,” said Yale School of Medicine PhD student Anis Barmada.
