Australian Influenza Surveillance Reports

This collection contains the historical fortnightly Australian Influenza Surveillance Reports (AISRs). We published these every fortnight during the influenza season, typically between May and October each year.

Collection description

This collection contains fortnightly AISRs published between 2019 and 2023, along with data consideration documents from 2018 and 2020.

View earlier reports on the Trove website. You will need to right click on the Word documents or PDFs to download them.

The AISRs were compiled from several data sources used to monitor influenza activity and severity in the community. Learn more about our work on influenza surveillance.

From 2024, the AISRs were replaced by the Australian Respiratory Surveillance Reports. They include information on acute viral respiratory illnesses including COVID-19, influenza and respiratory syncytial virus (RSV).

Influenza vaccine efficacy, effectiveness and impact explained

  • There are 3 terms used to describe how well a vaccine works in an influenza season:

    • vaccine efficacy
    • vaccine effectiveness
    • vaccine impact.

    The influenza vaccine efficacy document explains each of these terms as well as information specific to influenza vaccines.

We aim to provide documents in an accessible format. If you're having problems using a document with your accessibility tools, please contact us for help.
