Flu vaccination may cut heart attack and stroke risk after infection

In Danish adults aged 40 years or older, laboratory-confirmed influenza was linked to a sharp short-term rise in first-time heart attack and stroke risk, especially in the first 7 days after infection. Prior same-season influenza vaccination was associated with about half the excess cardiovascular risk among infected individuals, suggesting possible protection even in breakthrough cases.
