Getting a flu shot may protect you from more than just a case of the winter sniffles. Two Toronto-based researchers have presented studies at the Cardiovascular Congress which showed that the flu vaccine may be equally important for warding off cardiovascular events such as strokes and heart attacks.
The researchers looked at published clinical trials dating back to the 1960s. Across these studies the flu vaccine provided a risk reduction of a major cardiac event by approximately 50 per cent. This was the same for people with or without heart disease.
The combined studies looked at over 3200 patients, with an approximate 50/50 split between those with heart disease and those without. Half the participants were assigned a placebo, and the other half received a flu vaccine.
The results suggest that there is a good reason to get a yearly flu shot, whether or not you have a pre-existing heart condition.
