Influenza vaccines can change from year to year as new strains of influenza virus appear. This is one reason vaccination against influenza is given every year.
The Australian Influenza Vaccine Committee (AIVC) reviewed and evaluated epidemiology, antigenic and genetic data of recent influenza isolates circulating in Australia and the southern hemisphere. Serological responses to the 2022-2023 vaccines, and the availability of candidate vaccines viruses and reagents were also reviewed by the Committee. Based on this review and the World Health Organization's recommendation, the AIVC recommended the viral strains to be used for influenza vaccines in the 2024 southern hemisphere influenza season.
We have accepted the recommendations of AIVC. This year there is are new A (H1N1)pdm09-like and A(H3N2)-like virus strains when compared to the composition of quadrivalent vaccines for Australia in 2023.
The egg-based trivalent influenza vaccines contain the following three viral strains:
- an A/Victoria/4897/2022 (H1N1)pdm09-like virus
- an A/Thailand/8/2022 (H3N2)-like virus
- a B/Austria/1359417/2021 (B/Victoria lineage)-like virus.
Cell-based trivalent influenza vaccines contain the following three viral strains:
- an A/Wisconsin/67/2022 (H1N1)pdm09-like virus
- an A/Massachusetts/18/2022 (H3N2)-like virus
- a B/Austria/1359417/2021 (B/Victoria lineage)-like virus.
Quadrivalent egg- or cell culture-based or recombinant vaccines contain the following B/Yamagata lineage component:
- a B/Phuket/3073/2013 (B/Yamagata lineage)-like virus.
Influenza and COVID-19 vaccination
Can I have the Influenza and COVID vaccine at the same time?
COVID-19 vaccines can be co-administered (that is, given on the same day) with an influenza vaccine. Studies demonstrate the safety and immunogenicity of co-administration of COVID-19 and influenza vaccines.
Further information for health professionals and consumers regarding influenza and COVID-19 vaccines is available from the Australian Technical Advisory Group on Immunisation (ATAGI) website.

What is in the influenza vaccine?
Information on specific ingredients included within individual influenza vaccines can be found on the label of the medicine, the Product Information (PI) and Consumer Medicine Information (CMI) leaflets for each individual vaccine. You can ask your pharmacist for a copy or find it through our CMI database by searching the product's name. The CMI provides the full list of ingredients for each product.
Additionally, information on medicines supplied in Australia, including ingredients, can be located by searching the Australian Register of Therapeutic Goods (ARTG) either by product name or ARTG number.
Influenza vaccines available within Australia do not contain any thiomersal/mercury.
Formaldehyde is used in the early stages of manufacture of some influenza vaccines as an inactivation agent. The formaldehyde is removed in the latter stages of manufacture and the product is tested to ensure formaldehyde levels are below detectable limits before the final product can be released.
All influenza vaccines available this year are latex free. However, the possibility that the product may have come into contact with instruments which contain latex cannot be excluded. Patients who are extremely sensitive to latex should consult their doctor for advice.
Fluad Quad is the only product that contains an adjuvant to boost effectiveness of the vaccine in people aged over 65 years. Fluzone HD Quadrivalent has a higher content of antigen and designed specifically for use in the elderly.
Further information
Information for health professionals is available from the ATAGI Influenza Statement. This includes information on the timing of vaccines becoming available for the 2024 season and also the recommended interval between influenza and COVID-19 vaccines.
Information for consumers is available from NPS MedicineWise.

Reporting of adverse events following influenza vaccine
Health professionals and consumers are encouraged to report all adverse events associated with influenza vaccination in patients of any age to us or through the current arrangements in their state or territory.
All reports contribute to our ongoing monitoring of the safety of influenza vaccines.
We cannot give advice about an individual's medical condition. You are strongly encouraged to talk with a health professional if you are concerned about a possible adverse event associated with a vaccine or medicine.
