The flu vaccine may offer the extra benefit of heart disease protection, a new study shows.
Researchers at Women's College Hospital and the University of Toronto found that those who took the flu shot were half as likely to suffer from cardiac death or stroke.
CBS News reports that the study looked at 3,227 patients, half of whom suffered from heart disease. After one year, the results showed that those who received the vaccine were half as likely to die of a heart attack or stroke than those who took the placebo.
"For those who had the flu shot, there was a pretty strong risk reduction," said Jacob Udell, a cardiologist at Women's College Hospital and the University of Toronto, in a statement.
Researchers said the finding adds to the importance of getting the flu shot for people with a high risk of health problems.
The study was presented at the 2012 Canadian Cardiovascular Congress in Toronto.
