Study Finds Cardiac Inflammatory Effects on Pfizer Vaccine

Jakarta, CNBC Indonesia A recent New England Journal of Medicine study found there is a risk of heart inflammation in adolescents and young adults after being vaccinated against Covid-19 Pfizer/BioNTech. The risk is higher among those infected with the coronavirus.

Quotes Asia One, the researchers report based on data from Clalit Health Services, a major Israeli HMO. Where it is said that out of every 100,000 patients who get the vaccine, one to five are likely to develop myocarditis, inflammation of the middle layer of the heart wall.

The data comes days after Pfizer/BioNTech became the first vaccine to be fully approved in the United States (US) for people aged 16 and over. The researchers compared the rates of side effects in 884,828 individuals who were vaccinated and the same number of people who were not vaccinated.

Overall, 21 reported myocarditis in the vaccinated group of young men, compared with six in the unvaccinated group. Most side effects in vaccinated people are mild, but some are potentially serious, such as the appearance of myocarditis.

The researchers also analyzed the rate of side effects in more than 240,000 infected patients. The results show that Covid-19 infection itself is a very strong risk factor for myocarditis and also substantially increases the risk of other serious side effects.

“To me, this is a very good paper in part because it actually takes data from the same system, and tries to provide more information. Not only about the potential risks of vaccination, but also the potential benefits of vaccination,” said Dr GraceLee of Stanford University, whose editorial published with the report.

Not only the Pfizer vaccine, another mRNA vaccine, namely Moderna, is now also under regulatory scrutiny in several countries after several reports of cases of heart inflammation. Health regulators in a number of countries have investigated whether Pfizer-BioNTech and Moderna vaccines using the new mRNA technology pose a risk and if so, how severe the risk is.

WHO does not deny that there are side effects of the Covid-19 vaccine. However, it is emphasized that cases are very rare. Thus, the benefits of vaccines are still greater for the community.
