The COVID-19 vaccine can cut the risk of heart failure and blood clots after a COVID-19 infection, a new study in the British Medical Journal found.
Previous studies found that a SARS-CoV-2 infection can trigger cardiac and thromboembolic complications, and the risk for a person infected remains high for a year after becoming sick, researchers noted.
The new study found that while the risks remain, getting a vaccine slashes the risk of heart failure up to 55 percent and blood clots up to 78 percent after getting sick.
Using a sample of 10.17 million vaccinated people and 10.39 million unvaccinated people across three European countries, the study found the positive health effects were most significant in the 30 days following a vaccination but can last up to a year.
The study examined people who were vaccinated with Moderna, Pfizer, AstraZeneca and Johnson & Johnson.
