As we approach the 2026 influenza season, staying informed about the latest vaccine recommendations is crucial for individuals, families, and healthcare professionals alike. The Australian Technical Advisory Group on Immunisation (ATAGI) has released updated guidance for the administration of seasonal influenza vaccines in 2026 — offering clarity on eligibility, timing, and vaccine options for the year ahead.

Why Annual Flu Vaccination Matters

Seasonal influenza remains unpredictable — but vaccination continues to be the most effective way to prevent infection, complications, and hospitalisation. ATAGI strongly recommends that everyone 6 months of age and older receives an influenza vaccine every year. Healthcare provider recommendations also play a key role in increasing vaccine uptake across all age groups.

New in 2026: Expanded Vaccine Options

The 2026 influenza season brings notable updates:

Needle-Free Option for ChildrenFor the first time, a live attenuated influenza vaccine (LAIV) — delivered as a nasal spray — will be available in Australia for children aged 2 to 17 years. While highly effective, LAIV is not recommended for individuals with moderate to severe immunocompromise.
Trivalent Vaccine FormulationsAll influenza vaccines available in Australia this year are trivalent, protecting against two A strains and one B strain. This follows recommendations that the B Yamagata lineage is no longer circulating and therefore not included in vaccine formulations.
Expanded Adjuvanted Vaccine AccessThe adjuvanted influenza vaccine (Fluad®) — designed to enhance immune responses — is now registered for adults aged 50 years and older. Under the National Immunisation Program (NIP), it remains funded for people 65 years and above, while those aged 50–64 can access it through private providers.

Timing & Co-Administration Guidance

Influenza vaccines for 2026 are expected to become available around April 2026 — ahead of the peak flu season. Even if you received a flu shot late in 2025 or early 2026, ATAGI still recommends receiving the updated 2026 vaccine when it’s available.

Good news for convenience: influenza vaccines can be given at the same time as other vaccines (such as COVID-19 or RSV vaccines), which makes staying up-to-date far easier.

Who Is Eligible for Funded Vaccines in Australia?

Under the NIP, annual influenza vaccines are funded for:

All children aged 6 months to <5 years
Adults aged 65 years and above
Certain high-risk groups aged 5 to <65 years, including pregnant women, Aboriginal and Torres Strait Islander people, and those with medical conditions that increase flu risk.

Final Thoughts

Annual influenza vaccination remains among the best tools we have to reduce the burden of flu each year. Whether you’re a parent deciding on the best option for your child, a clinician advising patients, or an individual planning your own preventative care, the 2026 ATAGI guidance offers a strong foundation for making informed decisions.

Let’s make this flu season a healthier one — together.
