It has been just revealed the fact that there is a US military study on postvaccination myocarditis that details important issues. Check out the latest reports about this below.
US military study on postvaccination is out
The US military recently conducted a study to investigate postvaccination myocarditis, and the results have been released.
The authors of the study claim that they found no obvious or subtle inflammation in the heart. However, outside experts have pointed out that the study did reveal certain worrying signs, which the military researchers failed to investigate further.
It’s worth noting that the US military was one of the first organizations to identify myocarditis and pericarditis as potential side effects of COVID-19 vaccination.
In fact, the military made COVID-19 vaccination mandatory for all personnel.
With those facts in mind, “it is particularly important to understand the prevalence of subclinical myocarditis/pericarditis along with the potential for additional complications,” the authors of the new paper said.
As part of a study, researchers recruited individuals between the ages of 12 and 40 who received either the Pfizer or Moderna modified messenger RNA (mRNA) vaccine and were enrolled in TRICARE, a health care program for many service members and their families. These individuals had received their second or subsequent vaccine dose between June 2022 and June 2023.
The participants were required to visit investigators within 24 hours and three to seven days after vaccination. During these visits, their symptoms, troponin T levels, and C-reactive protein were measured.
Electrocardiograms were also used to assess the patients.
The study included a total of thirty individuals, out of which twenty-three were active-duty military personnel. Four participants showed an increase in troponin T levels, which is an indication of subclinical heart damage, from 1 to 16 nanograms per liter after being vaccinated.
However, the researchers stated that none of them had subclinical myocarditis as they defined it as an increase of more than 20 nanograms per liter. One participant reported chest pain and shortness of breath, which are possible signs of heart inflammation, but did not show any rise in troponin T levels.
“This is the first study to report on signs or symptoms of myocarditis/pericarditis collected through active surveillance following administration of mRNA vaccination in a military setting,” Dr. Richelle Homo, a pediatric resident at Madigan Army Medical Center and a fellow at Brooke Army Medical Center, and her co-authors wrote.
The authors recognized that the study was not of sufficient size to determine the frequency of myocarditis following vaccination due to the pandemic’s unpredictable nature and recruitment delays. As of June 2022, a significant number of individuals, including military personnel, had ceased receiving COVID-19 vaccinations.
