The risk of myocarditis, an inflammation of the heart wall, associated with the Pfizer vaccine, is lower than that of having the same pathology as an effect of Covid infection. This was stated by a study conducted on data from Israel published by the New England Journal of Medicine, according to which, however, the probability that immunization gives the side effect is very low.
For the study, the data of 880 thousand people over the age of 16 vaccinated with Pfizer were analyzed, each of which was ‘coupled’ to an unvaccinated one comparable in physical and demographic characteristics. The incidence rates of 25 potential adverse effects were calculated in the subjects, which in another analysis were calculated for a sample of 170,000 Covid positive people compared in turn with a control group. Although myocarditis remains a rare effect, the authors write, it was more common in vaccinated than in unvaccinated, with 2.7 more cases per 100,000 immunized. However, the risk of having myocarditis is much higher if you have had Covid, with 11 cases per 100 thousand people.
“The coronavirus is very dangerous – Ben Reis of Boston Children’s Hospital, one of the authors, tells the New York Times – and affects the body in many ways. If the reason why many are hesitant to get vaccinated is for fear of adverse events very rare and usually not very serious like myocarditis this study shows that the risk is much higher if you are not vaccinated and infected “.
