New research suggests COVID-19 vaccines may offer benefits beyond protection against coronavirus, the vaccines may also reduce the risk of heart failure and blood clots associated with SARS-CoV-2 It seems like it will.

The study, compiled by an international team of researchers, included analysis of data from 10.17 million vaccinated people and 10.39 million unvaccinated people in the UK, Spain and Estonia.

After taking into account factors such as age, gender and pre-existing medical conditions, vaccinated people have a significantly lower risk of heart and blood clot-related complications for up to a year after contracting COVID-19. It has been shown.

Nuria Mercade Besola, a data scientist at the University of Oxford in the UK, said: “Our research likely supports the fact that vaccines are effective in reducing infections and minimize the risk of severe COVID-19 infection. The results reflect that.”

“These results may encourage vaccination against COVID-19 among people who are hesitant and concerned about the potential risks of vaccine side effects.”

COVID-19 vaccination reduces risk of blood clots in veins by 78%, blood clots in arteries by 47%, and heart failure by 55% compared to unvaccinated people during the first 30 days after infection.

These risk reductions decreased over time, but were still 50%, 38%, and 48%, respectively, at 181 to 365 days. Although previous studies have found similar results, this is one of the most comprehensive studies to date in terms of number of participants and length of monitoring.

Blood clots and heart failure, which can lead to stroke, are known to occur much more frequently after coronavirus infection. Although the study does not prove a clear cause-and-effect relationship, it suggests that vaccination against the disease also reduces the risk of further complications.

COVID-19 vaccines have been shown to be mostly safe and effective, and researchers acknowledge the situation is complicated, with benefits outweighing potential drawbacks. But they hope further research will be carried out to look more closely at the protective effects of COVID-19 vaccines.

“The protective efficacy of vaccination is consistent with the known reduction in severity, but further research is needed to understand the effect of booster vaccination in different populations,” said Mercade-Besola. To tell.

This study heart.
