Vaccination may protect people from serious cardiovascular disease associated with COVID-19. As published in the European Heart Journal, researchers in Sweden studied risk windows in the time immediately after each of 3 doses of the COVID vaccine and assessed several outcomes. The risk of cardiovascular events for patients vaccinated with 3 doses was generally 20–30% lower than for those with no vaccinations. Additionally, stroke risk was lower after vaccination than without, while the risk of transient ischemic attack (TIA) was temporarily higher, mainly in older men.
Yes but: The authors note the increased risk of TIA was seen mainly after the second dose of the vaccine. “One speculation could be that people are more sensitized to new symptoms noticed after vaccination; thus, the increased risk can more likely be observed for more subjective or transient symptoms than harder, more objective outcomes.”
