About this year's flu vaccine

This year’s influenza vaccine contains strains that have changed from last year’s vaccine.  The 2016/2017 vaccine contains:

  • A/California/7/2009 (H1N1)pdm09-like virus
  • A/Hong Kong/4801/2014 (H3N2)-like virus
  • B/Brisbane/60/2008-like virus
  • B/Phuket/3073/2013-like virus (in quadrivalent vaccines only)

The vaccine will protect against influenza viruses that research indicates will be most common during this flu season.
