COVID-19 carries a far higher risk of heart inflammation than Pfizer’s coronavirus vaccine found a study from Israel. It has been estimated by the researchers in Tel Aviv that there were three cases for every 100,000 people inoculated with the Pfizer doses but risk of it was 11 per 100,000 in people who were infected with the virus.
Dr Grace Lee is an expert of infectious disease at Stanford University who says this research is the first to evaluate the possible risks of vaccination in the context of understanding the potential benefits of vaccination. The findings of the study were published in the New England Journal of Medicine on Wednesday.
The earlier reports have linked the Pfizer and Moderna vaccines to inflammation of the heart muscle. Mainly in male teens and young men, the problems were seen more, who reportedly developed chest pain a few days later the vaccination process.
According to the US health officials, they have confirmed about 800 vaccine-associated cases total of two types of inflammation – in the heart muscle and in the lining of the heart.
The researchers from Clalit Research Institute looked at hundreds of thousands of people who were vaccinated and not vaccinated. They separately looked at unvaccinated people who were infected or not. As two different groups of people were studied, the researchers were limited in making comparisons. The study focused only on the Pfizer vaccine, and it did not provide breakdown of results by age or sex.
