10 October 2025
The AIVC met in October 2025 and recommended that the following viruses be used for influenza vaccines in the 2026 Southern Hemisphere influenza season:
Egg-based vaccines:
Cell culture-, recombinant protein- or nucleic acid-based vaccines
The continued absence of confirmed detection of naturally occurring B/Yamagata lineage viruses after March 2020 is indicative of a very low risk of infection by B/Yamagata lineage viruses. Consistent with the World Health Organization (WHO) recommendations since September 2023, it remains the opinion of the WHO influenza vaccine composition advisory committee that the inclusion of a B/Yamagata lineage antigen is no longer warranted. There will no longer be updated recommendations for the B/Yamagata lineage component. This position is supported by the AIVC. Further, the AIVC supports the use of trivalent influenza virus vaccines within Australia for the 2026 influenza season.
