Longevity & AgingCovid Vaccines Linked to Lower Risk of Heart Attack, Stroke and Death in Major Study
A large new study published in JAMA Internal Medicine found that recent Covid vaccination offers broad heart-protective benefits. Researchers tracked more than 1 million veterans who received flu shots at VA facilities in 2024, about one-third of whom also got a Covid vaccine. Those who received the Covid vaccine showed meaningfully reduced rates of heart attacks, strokes, hospitalization, and death compared to those who only got the flu shot. The findings suggest Covid vaccines may do more than prevent infection — they appear to lower the risk of serious cardiovascular events. This is particularly relevant for older adults and those with existing heart risk factors, who stand to gain the most from vaccination as a cardiovascular protective strategy.
