2025 Flu Season Update: Key Changes to Vaccination Programs
As Australia prepares for the 2025 influenza season, significant updates are being rolled out to enhance vaccination efforts. Reflecting on the lessons of 2024 and incorporating fresh recommendations from leading health authorities, we’re here to keep you up to date with the latest developments.
Key Changes for 2025
The Australian Influenza Vaccine Committee (AIVC) has released its recommendations for the southern hemisphere influenza vaccines for 2025. Although discussions surfaced about a shift to Trivalent Influenza Vaccines (TIV), Australia will maintain its use of Quadrivalent Influenza Vaccines (QIV) in 2025 and will transition to TIV in 2026.

Recommended Vaccine Strains for 2025
The AIVC has outlined two specific formulations for the upcoming vaccines:
Egg-based vaccines:
- A/Victoria/4897/2022 (H1N1)pdm09-like virus
- A/Croatia/10136RV/2023 (H3N2)-like virus
- B/Austria/1359417/2021 (B/Victoria lineage)-like virus
Cell-based vaccines:
- A/Wisconsin/67/2022 (H1N1)pdm09-like virus
- A/District of Columbia/27/2023 (H3N2)-like virus
- B/Austria/1359417/2021 (B/Victoria lineage)-like virus
Update on the B/Yamagata Lineage
Although the B/Yamagata lineage component (B/Phuket/3073/2013-like virus) remains part of the quadrivalent vaccine, authorities note it has not been detected since March 2020. The World Health Organisation has recommended gradually phasing out this component, but for now, it remains included in the 2025 formulation in the Southern Hemisphere.
Corporate Vaccination Programs
Building on insights gained in 2024, we have carefully evaluated vaccine options for our corporate programs. While cell-based vaccines have demonstrated effectiveness comparable to egg-based alternatives, we are maintaining our use of standard quadrivalent vaccines. This approach continues to deliver strong protection at exceptional value for our corporate clients.
Looking Ahead
We remain committed to supporting workplace health through effective vaccination strategies. Our team will monitor developments and provide the latest expert advice to ensure your workplace vaccination programs remain effective and aligned with current health recommendations.

The Importance of Flu Vaccination in the Workplace
In the year-to-date (1st January to 9th December 2024), 359,693 notifications of laboratory-confirmed influenza were reported to the National Notifiable Diseases Surveillance System in Australia. Influenza can wreak havoc in the workplace, leading to increased absenteeism and decreased productivity. The 2025 flu vaccine is designed to combat the most common and virulent strains, making it an essential part of your workplace health strategy.
The Role of the WHO in Influenza Vaccine Recommendations
This helps ensure a good match between the vaccine strains and the circulating influenza viruses, which can positively affect Australian businesses and their employees.
A good match between the influenza vaccine and the circulating viruses means employees are less likely to fall ill and take time off work. This reduces absenteeism and increases productivity, benefiting the bottom line of businesses in Australia.
Furthermore, if employees are vaccinated, the spread of the flu virus within the workplace can be reduced, minimising the disruption and impact of flu outbreaks and leading to a healthy and efficient workforce.
The Importance of the Australian Influenza Vaccine Committee in Flu Vaccine Programs
The Australian Influenza Vaccine Committee (AIVC) plays a crucial role in the success of flu vaccine programs in Australia, including the Flu Vaccine 2025.
The committee, consisting of experts in virology, epidemiology, and public health, provides guidance on the use of flu vaccines, including the composition of seasonal flu vaccines, ensuring the Flu Vaccine for the upcoming flu season is a good match for the strains of influenza virus circulating in the population, providing maximum protection to individuals, including employees in the workplace.
