Could annual flu shot become thing of the past?

As flu season approaches, this is the time to get your flu shot, but getting that injection annually may one day be a thing of the past

Unlike vaccines for other diseases, a flu shot is only good for one season against a particular strain of influenza.

But researchers at the University of Oxford suggest change may be on the horizon. They are working on a vaccine that will target any type of influenza virus and make annual shots unnecessary.

Imagine a "universal flu vaccine." You would get two shots when you're young and then boosters later in life. Scientists believe this reality is within our grasp.
