Yahoo News Researchers from the Universities of Cambridge, Bristol, and Edinburgh have revealed that COVID-19 vaccinations may significantly reduce the incidence of arterial thromboses, a leading cause of heart attacks and strokes.
The study, published in Nature Communications and supported by the British Heart Foundation Data Science Centre at Health Data Research U.K., analyzed de-identified health records of 46 million adults provided by NHS England. Using health records from 45.7 million adults in England between December 2020 and January 2022, the study compared the incidence of thrombotic and cardiovascular complications up to 26 weeks after first, second, and booster doses of brands and combinations of COVID-19 vaccines used during the U.K. vaccination program with the incidence before or without the corresponding vaccination.
The incidence of common arterial thrombotic events (mainly acute myocardial infarction or heart attack and ischaemic stroke) was generally lower after each vaccine dose, brand, and combination.
