Influenza vaccination coverage data

NCIRS is monitoring and reporting influenza (flu) vaccination coverage data throughout the 2026 flu season. These data will be updated regularly between early April and the end of August 2026.

The intranasal live attenuated influenza vaccine (LAIV) FluMist is approved by the TGA for use in Australia for children and adolescents from 2 to less than 18 years of age. In 2026, it will be available free for children under some state-funded immunisation programs. 

To better align with these programs and the availability of LAIV on the private market, NCIRS is revising the age groups for which influenza vaccination coverage data is reported in 2026. 

Updated data will be made available from early April 2026.

Data calculation

These data, drawn from the Australian Immunisation Register (AIR), have been calculated based on the proportion of AIR-registered, Medicare-eligible people recorded as having received at least one dose of influenza vaccine since 1 March 2025 (or in the same period during 2020–2024) and by age at vaccination, and (for 2025 data only) state/territory of residence. 

AIR population denominators are presented: 

• as at the date of data extraction for 2025
• as at 30 June for 2020–2024.
