Perhaps another reason for a flu shot

I have no desire to get the flu, so flu shots are a matter of course for me every fall.

Now, another possible reason, too. Flu shots may lower stroke risk, too:

The researchers analyzed data from more than 47,000 people in the United Kingdom who suffered a stroke or mini-stroke (transient ischemic attack) between 2001 and 2009. The investigators found that having a flu shot was associated with a 24 percent lower risk of stroke. However, this association does not prove a cause-and-effect relationship.
The stroke risk reduction was strongest if a person received a shot early in the flu season, the study authors noted.
Note that, as the story notes, association does not mean cause. Still, not a bad move to make.
