Universal Flu Shots?

Scientists are getting closer in their quest for a universal flu vaccine that would protect people from all strains of influenza for decades or even a lifetime.  U.S. researchers studied the immune systems of people infected with H1N1, or swine flu, in 2009.  They found the survivors produced antibodies that could protect them from all H1N1 flu strains from the last decade as well as the Spanish flu and at least one strain of bird flu.  Researcher Patrick Wilson of the University of Chicago says the discovery shows that a universal influenza vaccine "is really possible."  The study appears in the "Journal of Experimental Medicine."
