Overview of key points and updates for 2018

  • Annual vaccination is the most important measure to prevent influenza and its complications.
  • Annual influenza vaccination is recommended for all persons ≥6 months of age.
  • For adults aged ≥65 years, in addition to the quadrivalent influenza vaccines (QIVs), two higher-immunogenicity
    trivalent influenza vaccine (TIV) formulations (one a ‘high-dose’ vaccine and another containing an adjuvant) are
    available and NIP-funded.
    • These TIVs are preferentially recommended over QIVs for adults aged ≥65 years. However, there is no
      preference for use between either of these two TIVs.
    • There is an increased likelihood of injection site reactions and systemic symptoms with these two TIVs, but no
      increase in the risk of severe adverse effects compared with standard TIVs.
