Flu Vaccine for 2015 -2016
Vaccine composition for 2015-16 will change from the 2014-15 formulation. Changes are in the A H3N2 virus and the influenza B virus. Both the A H1N1 virus and the second B virus in the quadrivalent vaccine will not change.
Certain children ages 6 months through 8 years will require TWO doses of vaccine, at least 4 weeks apart. These are children who have never had the vaccine, OR who had just 1 dose in their lifetime. See algorithm for decision-making:
For healthy people 2 through 49 years of age with no precautions or contraindications, either LAIV4 (FluMist) or inactivated vaccine can be used. There is no longer a preference for LAIV4 in children ages 2 to 8 years. LAIV4 is not clearly superior based on new data.
FluBlok is now approved for individuals 18 years and older, and can be used in adults with hives or a severe allergic reaction to eggs (e.g. hypotension, wheezing, etc - see Choosing Wisely Snapshot). An inactivated vaccine should be administered by appropriately trained personnel if the patient falls outside the approve age range for FluBlok or if FluBlok is not available. See algorithm with factors to consider when administering flu vaccine to egg-allergic patients:
FluZone Intradermal is now a quadrivalent vaccine. Fluarix, FluMist and FluLaval are now available ONLY as quadirvalent products.
See the attached chart for seasonal influenza vaccines for 2015-16, plus information such as FDA-approved ages for use, route of administration, dose and cost.
