Getting a flu shot may offer an added benefit. A recent study published in Stroke, an American Heart Association journal, suggests flu vaccination might lower the chances of stroke among adults, especially people under 45.
Dr. Gyanendra Kumar, a Mayo Clinic neurologist not involved in the study, says it's long been known that respiratory infections increase the risk of stroke in the days following infection.
Flu symptoms can come on suddenly, including cough, sore throat, fatigue and sometimes a fever.
