New York (AP) A study in Israel has said that COVID-19 carries a higher risk of heart inflammation than Pfizer’s coronavirus vaccine. Researchers in Tel Aviv estimate that there were three cases for every 100,000 people vaccinated with the Pfizer shot. But the risk was 11 per 100,000 of people infected with the virus.
The discovery was published Wednesday in the New England Journal of Medicine. Dr Grace Lee is an infectious disease specialist at Stanford University and says the paper is the first to assess the potential risks of vaccination in the context of understanding the potential benefits of vaccination.
Previous reports have linked Pfizer and Moderna vaccines to inflammation of the heart muscle. The problem was mainly seen in male teens and young men, who developed chest pain a few days after vaccination. US health officials say they have confirmed nearly 800 vaccine-linked cases, with a total of two types of inflammation — in the heart muscle and in the lining of the heart.
Researchers at the Clalit Research Institute looked at hundreds of thousands of people who were vaccinated and were not vaccinated. Separately, they looked at uninfected people who were infected or not. Because two different groups of people were studied, researchers were limited in making comparisons. The study focused only on the Pfizer vaccine, and did not provide a breakdown of results by age or gender. (AP).
