Flu Vaccine Links


Vaccination Recommendations

Recommendations from the Advisory Committee on Immunization Practices (ACIP) for the 2017-18 flu season can be accessed here.


  • Routine annual influenza vaccination of all persons aged 6 months and older continues to be recommended.
  • No preferential recommendation is made for one influenza vaccine product over another for persons for whom more than one licensed, recommended product is otherwise appropriate.
  • All 2017-18 trivalent (3-component) vaccines protect against these strains:
    •  A/Michigan/45/2015 (H1N1)pdm09–like virus (new for 2017-18)
    • A/Hong Kong/4801/2014 (H3N2)-like virus
    • B/Brisbane/60/2008-like virus (Victoria lineage)
  • In addition to the 3 strains in the trivalent vaccine, the quadrivalent vaccine also protects against B/Phuket/3073/2013-like virus (B/Yamagata lineage).
  • Live attenuated influenza vaccine (LAIV4) should still not be used, due to low effectiveness during prior flu seasons. 
  • Children aged 6 months through 8 years who have previously received 2 or more doses of trivalent or quadrivalent influenza vaccine before July 1, 2017 require only 1 dose for 2017-18. Children in this age group who do not meet these criteria require 2 doses for the 201-18 season. The interval between the 2 doses should be at least 4 weeks.
  • Recommendations for influenza vaccination of persons with egg allergies have not changed from the 2016-17 season.
  • Vaccination should begin as soon as vaccine is available with special emphasis on people with conditions that put them at increased risk for complications from influenza.
