COVID-19 Vaccines Reduce the Risk of Heart Failure: Why

 

COVID-19 Vaccines

Recent research sheds light on an additional aspect of the beneficial role of COVID-19 vaccines: Aside from their primary role of protecting against the coronavirus, they also appear to decrease the risk of heart failure and blood clots related to SARS-CoV-2.

The study, carried out by an international team of researchers, has involved a detailed analysis of data covering more than 10 million vaccinated and another 10 million unvaccinated people in the United Kingdom, Spain, and Estonia.

After adjusting for factors such as age, sex, and pre-existing medical conditions, the results revealed that those who had been vaccinated had a significantly lower risk of developing heart complications and blood clots related to COVID-19 infection, even up to a year after infection.

Data scientist Núria Mercadé-Besora, from the University of Oxford in the United Kingdom, who was part of the research team, said: “Our findings probably reflect the fact that vaccines are effective in reducing infection and minimizing risk.” of severe COVID-19.”

These results, he added, could be an encouragement to those who are hesitant about getting vaccinated, especially those concerned about possible side effects of the vaccine.

Compared to unvaccinated people, those who received the COVID-19 vaccine showed a 78% reduced risk of blood clots in the veins, a 47% lower risk of blood clots in the arteries, and a 55% lower risk of blood clots in the arteries. in the risk of heart failure in the first 30 days after infection.

Although these reductions in risk attenuated over time, they were still significant, with a decrease of 50%, 38%, and 48%, respectively, between 181 and 365 days post-infection. This study adds to a series of previous research that also suggests the protective effects of COVID-19 vaccines in terms of heart complications and blood clots.

It is well known that blood clots and heart failure are common complications after a COVID-19 infection. Although this study does not establish a direct causal relationship, it does suggest that vaccination against the disease can also reduce the risk of these complications.

The research team recognizes the complexity of the landscape but emphasizes that COVID-19 vaccines are mostly safe and effective and that the benefits outweigh the potential risks. However, they highlight the need for more research to better understand the protective effects of vaccines, especially in different populations and with booster doses.

“The protective effects of vaccination are consistent with known reductions in disease severity, but more research is required to fully understand the effects of a booster vaccination in different groups of people.”

This study represents a significant step in understanding the broader benefits of COVID-19 vaccination and could serve as an additional incentive to promote immunization worldwide.
