Study shows COVID vaccines reduce risk of heart failure and blood clots after virus infection

Researchers found that COVID-19 vaccines can reduce the risk of heart failure by up to 55% and blood clots by up to 78% after a COVID infection in a study published in the British Medical Journal. The positive health effects can last for up to a year and are more pronounced immediately after vaccination. Dr. John Brownstein, Chief Innovation Officer at Boston Children’s Hospital, mentioned that the risk of complications like myocarditis and thromboembolic events is higher with the SARS-CoV-2 infection compared to vaccination.

The research involved over 20 million people in Europe, half of whom were vaccinated with Moderna, Pfizer, AstraZeneca, and Johnson & Johnson vaccines. The study looked at the original COVID strain and the Delta variant. Within a month of receiving the dose, COVID vaccines reduced the risk of blood clots in the veins by 78%, blood clots in the arteries by 47%, and heart failure by 55%.

After the six-month period post-vaccination, the study showed that COVID vaccines decreased the risk of a blood clot in the vein by 47%, a blood clot in an artery by 28%, and heart failure by 39%. Dr. Brownstein emphasized that these results prove that COVID-19 vaccines play a critical role in reducing the chances of long-term health issues following a COVID infection.

Moreover, the U.S. Centers for Disease Control and Prevention have approved an additional updated COVID-19 vaccine for adults over the age of 65 to prevent severe hospitalization and death. The study’s findings highlight the importance of vaccination in reducing the risks associated with COVID-19 infection and its long-term health effects.
