Show your support this flu season and tag flu prevention and flu vaccine social media messages with the hashtag #FightFlu! Share Fight Flu messages to encourage everyone in your social communities to get a flu vaccine this season. CDC recommends everyone 6 months and older get a flu vaccine by the end of October, if possible.
Note: For the 2016-2017 season, CDC recommends use of the flu shot (inactivated influenza vaccine or IIV) and the recombinant influenza vaccine (RIV). The nasal spray flu vaccine (live attenuated influenza vaccine or LAIV) should not be used during 2016-2017. The 2016-2017 influenza vaccination recommendations are now available.
