    CDC-Recommended Tips on Avoiding the Flu at Work

    The CDC recommends getting a flu shot early during flu season.

    There's a good reason not to skip the flu shot this year: a new study has found that older adults who get the shot every flu season were less likely to die or be hospitalized with severe complications, NBC News reported.

    People over 65 who got the flu shot every year but were taken to the hospital with influenza were twice as likely not to get severe complications of flu or die, according to the study, published this week in the Canadian Medical Association Journal.

    "We probably only get exposed to influenza, the virus, every three to five years on average," said University of Rochester Medical Center immunologist David Topham, who was not involved in the research. "That's plenty of time for your immunity to wane."

    The flu season is off to a strong start in the U.S. this year, with some emergency rooms filling up.
