Influenza vaccine is available in some clinics and retail pharmacies.

The composition of the 2016-2017 trivalent influenza vaccine is:

  • A/Michigan/45/2015 (H1N1) pdm09-like virus.
  • A/Hong Kong/4801/2014 (H3N2)-like virus.
  • B/Brisbane/60/2008-like virus (B/Victoria lineage).

Quadrivalent influenza vaccines include a second influenza B virus:

  • B/Phuket/3073/2013-like virus (B/Yamagata lineage).

Changes/modifications in flu vaccine recommendations for 2017-2018:

  • Because of low effectiveness against 2009 pandemic strain of influenza A-H1N1, CDC does not recommend the live-attenuated influenza vaccine (LAIV, Flumist) for any age group for the 2017-2018 season.
  • Pregnant women may receive any licensed, recommended, and age appropriate influenza vaccine. Live vaccines, including LAIV, should not be used during pregnancy.
  • Two quadrivalent influenza vaccines are licensed for children ≥ 6 months of age. Be aware that the volume administered differs. The volume of Fluzone Quadrivalent administered to children 6 to 35 months of age is 0.25 ml. The volume of FluLaval Quadrivalent administered to children in that age group is 0.5 ml; the same dose for older children and adults.

CDC recommends flu vaccination for all people age > 6 months without contraindications. Prioritize groups at high risk for complications of influenza, including:

  • Children age 6-59 months.
  • People > age 50.
  • Women who are or will be pregnant.
  • People with chronic pulmonary (including asthma) or cardiovascular disease, diabetes, or chronic renal, hepatic, neurologic or hematologic conditions.
  • People with immunosuppression.
  • Children on long-term aspirin therapy.
  • American Indians/Alaska Natives.
  • Extremely obese people (BMI > 40).

It is extremely important to vaccinate health care workers and others who have contact with vulnerable people, including child care workers and household contacts of young infants or others at high risk for influenza complications.

Children ages 6 months through 8 years should receive two flu vaccines four weeks apart if they have not received two or more doses in previous seasons.
