You’ve probably already heard that a flu shot is one of the best ways to stay flu-free during the fall and winter.

But did you know that there are a few other conditions that the flu shot may help protect you from as well?

Strokes & Heart Attacks

New suggests the influenza vaccine can prevent strokes and heart attacks in people with or without heart disease.

The flu vaccine lowered risk of major cardiac events (like heart attacks, strokes, or cardiac deaths) by 50 percent compared to a placebo after a one-year period, found a review of published clinical trials dating as far back as the 1960s. Lead study author Jacob Udell, MD, a cardiologist at Women’s College Hospital and the University of Toronto, and his team, also noted a similar lower risk for all-cause death, by about 40 percent.

While Dr. Udell thinks a larger study could further demonstrate the flu shot’s benefits for heart health, according to a release from the Heart and Stroke Foundation of Canada, he said the results support current recommendations for influenza vaccination of people who have had heart attacks.
