Health officials say less than half of Michigan's high-risk adult population has received a flu shot this season. But there still is time to get a shot.
Flu season in Michigan typically does not peak until January or February. That means shots received in December or January can still be effective against the flu.
Health officials say anyone who wants a shot should be able to get one if they ask their doctor.
The most at risk for the flu include adults over 65, pregnant women, people with chronic diseases, and children between six months and two years old.
