"Vaccination is the single most important step everyone 6 months of age and older can take to protect themselves and their families against influenza," said Frieden.  Influenza hospitalized a surprisingly high number of young and middle-aged adults last winter, and this time around the government wants more of them vaccinated. (AP Photo/J. David Ake)
