Please see the WA Immunisation Schedule and refer to the Influenza chapter on the Australian Immunisation Handbook (external site) for detailed advice, including vaccine dosage, and contraindications.

Free influenza vaccines will be available during May and June to all Western Australians aged 12 to 64 years who do not meet the above eligibility.

Providers should consider vaccinating in the months prior to the peak influenza season, which typically spans July to October in WA. Influenza vaccination should continue to be offered while the influenza virus remains in circulation, and a valid vaccine is available.

For a brief summary of General Practice and hospital emergency department sentinel surveillance data on influenza-like illness, subscribe to Virus WAtch (a weekly electronic publication by CDCD and key collaborators).  For Australian Influenza Surveillance Reports, visit the Australian Government Department of Health and Aged Care website (external site).

Optimal protection against influenza occurs within 3 to 4 months following vaccination. During the influenza season, look for opportunities to provide influenza vaccination to persons at increased risk of influenza during visits for routine medical care.

If a person had a 2023 formulation influenza vaccine in late 2023 or early 2024, they are still recommended to receive a 2024 formulation influenza vaccine.

People who are planning international travel should ensure they have had a 2024 influenza vaccination before departure.

• Providers are highly recommended to review the 2024 Australian Technical Advisory Group on Immunisation (ATAGI) Statement on the administration of seasonal influenza vaccines (external site).
• The influenza module on Immunisation education has been updated for 2024. Completion of the module is recommended for all immunisation providers and compulsory for those working under the CEO of Health SASA .The Immunisation education webpage also contains a link to the influenza update session. (March 2024).
• Influenza vaccine can be co-administered with most other vaccines (external site), including COVID-19 vaccines.

It is a mandatory requirement for immunisation providers to report influenza vaccine administrations to the Australian Immunisation Register (external site). Ensure you are using the correct brand name, dose number and batch number.

The new ‘vaccine type’ field should be used to record specific details of the vaccine administered, e.g. National Immunisation Program (NIP) or state funded. If the recipient is pregnant, antenatal should be selected in preference over the funding source.

Refer to Immunisation provider information and resources webpage for more information.

AusVaxSafety (external site) conduct routine safety monitoring of seasonal influenza vaccines. Surveillance data are based on vaccine safety surveys sent in the days following influenza vaccination.

This rapid safety surveillance can provide reassurance to individuals that the influenza vaccines used in Australia are safe. To learn more about the latest vaccine safety data, including specific age and population groups, visit AusVaxSafety (external site)

Refer to the Adverse events following immunisation webpage for information about reporting any adverse events following an influenza vaccine.

The adjuvanted Fluad® Quad vaccine is preferentially recommended for persons aged 65 years or over. This product is not licensed or recommended for anyone aged <65 years.
