A study carried out using some members of the United States military showed that some who were vaccinated rendered a much higher than expected rate of heart inflammation. However, it was further added that the cases are extremely rare.

23 healthy male individuals with an average age of 25 complained about chest pain within four days after getting a COVID-19 jab. The incident rate was higher compared to the previous estimated, the study stated. The patients at the time reportedly had recovered or were recovering from myocarditis, an inflammation of the hurt muscle.

They received COVID-19 jabs from Pfizer, BioNTech SE or Moderna, Reuters reported.

These findings come not long after U.S. health regulators added a warning to the literature that accompanies those mRNA vaccines to flag the rare risk of heart inflammation seen primarily in young males. However, the benefits of taking the jab still outweighed the risks.

The study can be found at the JAMA Cardiology medical journal. 19 patients who are current military personnel had already gotten their second vaccine dose. Others had received one dose or were retired servicemen.

According to a group that advised the US Centers for Disease Control and Prevention (CDC), reports of myocarditis were higher in males and the week after the second vaccine dose than would be anticipated in a general population. In that presentation, it was found that the heart condition turned up at a rate of about 12.6 cases per million people vaccinated.

Eight of the military personnel in the study underwent diagnostic scans and showed signs of heart inflammation that could not be explained by other causes, the study noted. The ages of the patients in the study ranged from 20 to 51.

The CDC started investigating links between myocarditis and mRNA vaccines in April. This was after Israel started studying cases on people who received the Pfizer/BioNTech vaccine and following reports that the US military also had found cases.

Other country health regulators continue to conduct their investigations as well.
