It Might Spare You a Heart Attack
It's true. A study published in JAMA last October found that adults who'd gotten a flu shot were 36 percent less likely to suffer a heart attack or stroke within the next year than those who weren't vaccinated. According to study author Dr. Jacob Udell, a cardiologist at the University of Toronto, influenza causes inflammation throughout your whole body, which can cause the plaque that's built up in your arteries to dislodge and form a blood clot. Blood clots often lead to heart attack or stroke. However, if you've been vaccinated and you do get exposed to the flu, Udell says your body will be ready to mount an immune response to tame this inflammation before it turns deadly.
