If you haven't gotten around to getting your flu shot yet, new research might change your mind. Data from 31 studies points to the fact that flu vaccines don't work as well as previously thought. For adults ranging in age from 18 to 65, the shot is only 59 percent effective. This news is rather depressing, but experts still say a flu vaccine is your best bet at protection against influenza.
