(Newser) – The flu shot may be good for you in more ways than one. A new study, published in the Canadian Medical Association Journal, found that adults who took the flu vaccine were less likely to experience their first heart attack in the following year, CNN reports. Researchers looked at the medical records of more than 16,000 first-time heart attack sufferers, age 40 and over, and almost 62,700 who hadn’t had an attack.

After factoring out other risk factors like smoking or family history, they found that those who took the shot were 19% less likely to suffer their first heart attack. “By the nature of the study, it does not prove cause and effect,” said one of the authors, but it does show a strong association.
