Get ready for the 2026 Southern Hemisphere influenza season! It's time to talk about the annual flu vaccine and some exciting updates. Influenza, a sneaky virus, evolves and adapts, which is why we need a new vaccine each year.
The Australian Influenza Vaccine Committee (AIVC) has been hard at work, reviewing data and making recommendations for the upcoming season. And here's where it gets interesting: two new viral strains, A(H1N1) and A(H3N2), have been added to the mix compared to last year's vaccine composition.
But let's break it down. The egg-based trivalent influenza vaccines will contain three specific viral strains, each with its unique identifier, like A/Missouri/11/2025 (H1N1)pdm09-like virus. Similarly, cell-based trivalent vaccines will have their trio of strains.
Now, here's a controversial point: the World Health Organization (WHO) recommends excluding the B/Yamagata lineage component from seasonal influenza vaccines. Why? Because this lineage of the influenza B virus hasn't been active for several years. The AIVC supports this position, and thus, all 2026 southern hemisphere seasonal influenza vaccines in Australia will be trivalent, excluding the B/Yamagata lineage.
And this is the part most people miss: you can get your flu vaccine and COVID-19 vaccine at the same time! Studies show it's safe and effective. So, no more waiting around; you can protect yourself from both viruses simultaneously.
For the 2026 influenza season, seven vaccines will be available in Australia, each with its target age group. AstraZeneca's FluMist, a live attenuated influenza vaccine, is a new addition to the market this year. It's a nasal spray, so no needles!
Some vaccines, like Fluzone and Influvac, will only be available on the private market, while others, like Flucelvax and Vaxigrip, will be free through the National Immunisation Program (NIP). FluMist will also be available privately and through state-sponsored programs in certain states.
Now, a quick note on ingredients: all the information you need about specific ingredients in each vaccine can be found on the product labels, Product Information documents, and Consumer Medicine Information leaflets. Seasonal influenza vaccines in Australia are mercury-free and latex-free, but some may have come into contact with latex-containing instruments, so extremely sensitive individuals should consult their doctors.
Fluad is the only vaccine with an adjuvant, designed to boost the immune response in people over 50. Fluzone HD has a higher antigen content. And for those curious about the manufacturing process, six of the seven seasonal vaccines use eggs, while Flucelvax is produced using mammalian cell culture, making it egg-free.

And if you experience any adverse events after your influenza vaccine, don't hesitate to report them to us or your state/territory health authorities. Your reports contribute to our ongoing safety monitoring efforts.
So, there you have it! A comprehensive guide to the 2026 influenza vaccines. Stay informed, stay healthy, and don't forget to share your thoughts and experiences in the comments. We'd love to hear your feedback and any questions you might have.
