Flu shots lower risk of blood clots

"People who get their annual flu shot may reap an extra benefit: a reduction in their risk of developing a blood clot. The benefit appeared stronger in those under the age of 52, according to research that was presented Sunday at the American Heart Association's annual scientific sessions, in New Orleans. The findings, the first to demonstrate such an effect, may help explain why the flu shot lessens the risk of cardiovascular events in people with coronary artery disease, but the real current value of the data may lie in it convincing more people to get their annual shot" - HealthDay
