Study shows COVID vaccines decreased heart attacks and strokes. A sweeping analysis of nearly 46 million adult health records has delivered a clear verdict: COVID-19 vaccination sharply lowers the risk of heart attacks and strokes, directly refuting persistent claims to the contrary. Published in Nature Communications, the study followed people across England from December 2020 through January 2022. It documented a 10% drop in serious arterial blood clots (including heart attacks and strokes) after the first dose alone. Protection strengthened further with subsequent doses: a 20% reduction among those fully vaccinated with Pfizer/BioNTech and a striking 27% reduction for AstraZeneca recipients. The researchers were upfront about rare side effects—myocarditis and certain clotting disorders—that can occur shortly after vaccination, but stressed these remain exceptionally uncommon. By comparison, catching COVID-19 itself dramatically raised the odds of major cardiovascular events. Lead co-author Dr. Samantha Ip described the results as some of the strongest evidence yet that the vaccines do more than prevent severe infection: they also confer lasting protection against two of the world’s leading killers.
