What are the influenza vaccine strains for 2022?

For 2022, of the four influenza strains included in the quadrivalent vaccines, the two in bold listed below are new:

  • A/Victoria/2570/2019 (H1N1)pdm09-like virus
  • A/Darwin/9/2021 (H3N2)-like virus
  • B/Austria/1359417/2021-like virus
  • B/Phuket/3073/2013-like virus

How are influenza vaccines produced?

  • AFLURIA QUAD and AFLURIA QUAD JUNIOR are split virion vaccines that contain disrupted haemagglutinin proteins from the surface of the virus. Influenza virus is grown in embryonated hens’ eggs from disease-free flocks and inactivated. The haemagglutinin protein for each strain is harvested, purified and inactivated for use in the vaccine.
  • FLUAD QUAD is an inactivated vaccine that contains inactivated haemagglutinin proteins from the surface of the virus and a squalene-based oil-in-water emulsion. Influenza virus is grown in embryonated hens’ eggs and inactivated with formaldehyde. The haemagglutinin protein for each strain is harvested, purified and combined with the MF59 squalene-based oil-in-water adjuvant.
  • FLUQUADRI is a split virion vaccine that contains inactivated influenza virus grown in embryonated hens' eggs. The virus is harvested and inactivated with formaldehyde. Antigens from the four strains included in the vaccine are produced separately, then combined to make the quadrivalent formulation.

Needles for FLUAD QUAD and FLUQUADRI

Needles are available for purchase from EBOS Healthcare or pharmacy wholesalers.

  • FLUAD QUAD vaccines are supplied without needles.
  • FLUQUADRI needles are unattached, and included separately with the vaccines.

At the time of vaccination, the choice of needle gauge and length will be based on the vaccinator’s clinical judgment to ensure needle length is appropriate to reach muscle. Table 2.8 in the online Immunisation Handbook 2020 provides guidance on the needle gauge and length by site and age.
