While current U.S. flu activity is low overall, localized influenza outbreaks have been reported and activity is expected to increase in the coming weeks.  CDC recommends a yearly flu vaccine for everyone 6 months and older. Now is a good time to get vaccinated. It takes about two weeks after vaccination for protection to set in.  Flu vaccination can reduce flu illnesses and prevent flu-related hospitalizations. Flu vaccines have been updated for the 2016-2017 season. More than 127 million doses of seasonal influenza vaccine have been distributed at this time.
