Influenza vaccine safety data – 6 months to younger than 5 years

Data on this page show the responses of parents and carers of individuals aged 6 months to younger than 5 years who received a standard influenza vaccine in 2025 and completed an AusVaxSafety survey sent in the days following vaccination.

Standard influenza vaccines currently in use in this age group include:

• Flucelvax Quad
• FluQuadri
• Influvac Tetra
• Vaxigrip Tetra.

These data provide a profile of what to expect in the days following your child’s influenza vaccination and can assist in planning for vaccination.

Data on this page will be updated weekly throughout the 2025 influenza season.
 

AusVaxSafety's active vaccine safety surveillance system complements the enhanced safety surveillance activities of the Therapeutic Goods Administration.

Further information and resources on the 2025 influenza vaccines are available on the NCIRS influenza immunisation webpage.
