It's time for a flu shot.
You can get the flu vaccine from your doctor, and at public health facilities, senior centers, pharmacies and supermarkets. The vaccine can be administered anytime during flu season.
Adults over 50 are prime candidates for the vaccine because the flu can be fatal for older people.
More than 200,000 flu victims are hospitalized annually in the United States; about 36,000 people die from it. As much as 20 percent of the U.S. population gets the flu each year. Flu season usually begins in October and can last through May.
