Possible link between mRNA vaccines and heart inflammation in young men.

A recent study has found that COVID mRNA vaccines may cause rare heart inflammation among young men due to overactive immune responses. The study was conducted on 23 patients aged 12 to 21 who developed myocarditis after receiving the second dose of Pfizer-BioNTech or Moderna vaccines. The study found that higher cytokine levels in the blood samples of patients who received Pfizer jabs may cause inflammation. The researchers hope larger trials will confirm their findings, although finding more participants could be difficult as the condition is very rare.
