Flu Vaccine Linked to Decreased Risk of Heart Attack

The New York Times’ Well blog reports that flu vaccines may be tied to positive cardiovascular outcomes. A study published in JAMA reviewed 5 randomized clinical trials comparing influenza vaccine versus controls in patients with high risk of cardiovascular disease. Risk ratios were obtained for “composite cardiovascular events, cardiovascular mortality, all-cause mortality, and individual cardiovascular events.” Researchers found that for patients with a stable heart disease, receiving a flu vaccine decreased the likelihood of suffering a heart attack by 36% while for patients who had suffered a heart attack within the last year the decrease was even greater, at 55%. Researchers also found that “over all, those who were vaccinated had a 19 percent reduced risk of death.”
