Flu Shot Didn't Protect Three-Quarters Of People Against Most Common Strain
While the vaccine was more effective against influenza B viruses (42 percent protection) and H1N1 viruses (67 percent protection), that is cold comfort given that those viruses have been much more minor players this flu season, at least to date. That is especially true of H1N1; only about 8 percent of people who had a positive flu test this season were infected with viruses from that influenza A family. (Branswell, 2/15)
