Having the seasonal flu jab could reduce the risk of suffering a stroke by almost a quarter, researchers have found. Academics discovered that patients who had been vaccinated against influenza were 24% less likely to suffer a stroke in the same flu season. In 2010, the same research team showed a similar link between flu vaccination and reduced risk of heart attack. "Further experimental studies would be needed to better understand the relationship between flu vaccination and stroke risk. However, these findings reinforce the value of the U.K.'s national flu vaccination program with reduced risk of stroke appearing to be an added health benefit," the authors noted.
