The Advisory Committee on Immunization Practices (ACIP) has issued new guidelines for the prevention and control of seasonal influenza with vaccines for the 2019–2020 season.

For the 2019–2020 season, the following influenza vaccines will be available:

  • Trivalent influenza vaccines (A/Brisbane/02/2018 (H1N1)pdm09–like virus, A/Kansas/14/2017 (H3N2)–like virus, B/Colorado/06/2017–like virus [Victoria lineage])
  • Quadrivalent influenza vaccines (includes 3 viruses + additional influenza B virus hemagglutinin, a B/Phuket/3073/2013–like virus [Yamagata lineage])
  • Standard-dose, unadjuvanted, inactivated influenza vaccines will be available in quadrivalent and trivalent formulations
  • Recombinant influenza vaccine and live attenuated influenza vaccine (LAIV4) will be available in quadrivalent formulations
  • High-dose inactivated influenza vaccine and adjuvanted inactivated influenza vaccine will be available in trivalent formulations

In general, routine annual vaccination is recommended for all patients ≥6 months of age who have no contraindications. Flu vaccine should be offered to patients by the end of October, if possible.
