COVID Vaccine Cuts Heart Risk by 40%
16 Jun
Summary
- COVID vaccine reduced virus-linked cardiovascular risks by 40%.
- Study found nearly 60% lower risk of cardiovascular death.
- Vaccine offered broader health benefits, reducing all heart conditions by 6%.
A recent study published in JAMA Internal Medicine reveals that the COVID-19 vaccine lowered the risk of cardiovascular issues linked to the virus by approximately 40 percent. This research, which analyzed over one million veterans within the Department of Veterans Affairs health system between 2024 and 2025, found significant reductions in various heart-related events.
The vaccine decreased the risk of cardiovascular death by nearly 60 percent, heart attack by around 40 percent, and stroke by over 30 percent. It also reduced the risk of hospitalization for heart failure by about 40 percent. Individuals over 75 and those with pre-existing health conditions experienced the most substantial risk mitigation.
Further analysis showed a 37.7 percent lower risk of heart conditions related to the virus among veterans who received both the flu and COVID-19 vaccines compared to those receiving only the flu vaccine. The study also identified a wider health advantage, including a 6 percent decreased risk of all heart conditions and a 7 percent reduction in overall deaths and hospitalizations.
