Incidence of cardiovascular events was lower after covid-19 vaccination, study finds

The incidence of cardiovascular events, such as strokes, heart attacks, and blood clots, was lower after covid-19 vaccination than before or without vaccination, a study of the English adult population has found.1

Using de-identified health records from 45.7 million adults in England between December 2020 and January 2022, researchers from several UK universities compared the incidence of thrombotic and cardiovascular complications up to 26 weeks after first, second, and booster covid-19 vaccine doses with the incidence before or without vaccination.

They found that the rate of arterial thrombotic events (such as acute myocardial infarction, ischaemic stroke, and other arterial embolism) and common venous thrombotic events, (mainly pulmonary embolism and lower limb deep venous thrombosis) was lower after vaccination.
