Since they started moving in December 2020, people have become well aware of the mostCurrent side effects of COVID-19 vaccines, thanks to the warnings of public health officials and experts. Fortunately, most of the symptoms encountered after receiving the shots are non-serious, especially fatigue, headaches, pain at the injection site or a soft fever, which all disappear in a few days after receipt of the dose. But in recent weeks, the United States centers for disease control and prevention (CDC) recognized another incredibly rare but potentially serious side effect that mainly affects younger men - and a new study now finds that This can be three times more common than the agency originally thought.

The last conclusions come from research published by the US military in the newspaperJama Cardiology June 29th. The great study revealed thatCase of cardiac inflammation Have been reported from 23 men in physical fit and earlier health of 25-year-olds within four days of receiving a dose of Pfizer or Moderna Roon Covid-19 vaccines. While the incidence of the side effect - which is medically known as myocarditis - was still rare extremely rare, the number was stillthree times higher that the eight cases or less that would have been typically estimated for the 436,000 male military members who received the two doses.

At the time of the publication of the study, the 23 patients had recovered or recover from the delayed side effect. However, the authors of the study concluded that "while the observed number of myocarditis cases was small, the number was higher than expected among male military after a second dose of vaccine."

The study comes after the Food and Drug Administration (FDA) announced on June 25 which it adds aWARNING TO MODERNA AND PFIZER VACCINES On the high risk of myocarditis or pericarditis as a potential delayed side effect, especially after the second dose. But the data show that it is always incredibly rare: June 11, more than1,200 case of myocarditis or pericarditis It would have been reported to the US adverse event reporting system (VAERS) of about 300 million doses of RMNA vaccines, Reuters Reports.

While the new FDA warning notes that the possibility of living cardiac inflammation is "very low", they urge the recipients of Pfizer and Moderna to "seek medical attention right away" if they notice symptoms such as Thoracic pain, shortness of breath or feelings of having a floating, fast or hammer heart.

In a statement following a meeting of 23 June confirming the "probable association" betweenMRNA vaccines and cardiac inflammationThe CDC Advisory Committee on Vaccination Practices (ACIP) has published a report similar to that of the FDA. "The facts are clear: it's aExtremely rare side effectand only an extremely small number of people will experiment after vaccination, "they said." Above all, for young people who do, most cases are light and individuals often recover by themselves or with treatment. Minimal. In addition, we know that myocarditis and pericarditis are much more common if you get COVID-19 and that the risks for the heart of a Covid-19 infection can be more serious. "
