Seasonal influenza vaccine

Eligibility for the free influenza vaccine

Free seasonal influenza vaccine is funded under the National Immunisation Program (NIP) for the following groups at higher risk of complications from influenza:

• people aged six months to less than five years (can be given at the same time as childhood vaccines)
• Aboriginal and Torres Strait Islander people aged six months and older
• pregnant women (can be given at any stage of each pregnancy)
• people aged 65 years and older (a vaccine that is specifically designed to produce a higher immune response is available for this group).
• people aged six months and older with medical conditions putting them at increased risk of severe influenza and its complications.

Refer to 2025 Influenza vaccination – Program advice for health professionals for a list of medical conditions that meet eligibility criteria for the funded influenza vaccine.

Timing of influenza vaccination

Annual influenza vaccination is recommended for everyone from mid-April onwards to be protected for the peak influenza season, which is typically June to September.

Influenza vaccination should continue to be offered as long as influenza virus are circulating, and a valid vaccine is available. Some important considerations are:

• Young children aged 6 months to less than 9 years who should have 2 doses of influenza vaccine (given at least 4 weeks apart) in the first year they receive the vaccine.
• Pregnant women (should receive the vaccine at any stage during pregnancy)
• People travelling to a destination where influenza is circulating (year-round in the tropics)
• People who have had a haematopoietic stem cell or solid organ transplant require two doses, given at least 4 weeks apart, the first time after they receive the transplant.

Refer to 2025 influenza vaccination – Program advice for health professionals for further details.

Clinical guidance

Updated advice is available from the Australian Technical Advisory Group on Immunisation (ATAGI) Statement on the administration of 2025 seasonal influenza vaccines for immunisation providers, including vaccines available for use in by age, and eligibility criteria for NIP funded vaccine.

Refer to the Australian Immunisation Handbook for contraindications and precautions relating to 2025 Influenza vaccines.

• All influenza vaccines available under the NIP in 2025 are latex free and people with a latex allergy can be safely vaccinated.
• It is safe to administer the influenza vaccine at the same time as the pertussis vaccine (20 to 32 weeks), RSV vaccine (28 to 36 weeks), COVID-19 vaccine (if required), or other vaccines indicated during pregnancy.
• Influenza vaccines can be co-administered with any of the COVID-19 vaccines. Refer to ATAGI Clinical recommendations for COVID-19 vaccines for considerations for co-administration of COVID-19 and Influenza vaccines for children aged 6 months to less than 5 years.
