Want to start a spirited debate among friends? Find out who's pro-flu shot and who's anti-flu shot, split them up into teams, then sit back and watch the show! You know what I'm talking about: There are people who swear by the flu shot and others who think it's poison, and never the twain shall meet. Or so it seemed, until this year.
That's because this year, the flu shot is falling short. Big time. While the vaccine is usually between 50% and 70% effective, this season's shot worked for only 56 percent of people who got it -- AND "it largely failed to protect the elderly against an especially deadly strain circulating during flu season."
And that's not all. While the flu shot's side effects are largely downplayed, there's a significant amount of data suggesting the vaccine may do more harm than good.
