Overview Overview

About Vaxtracker

Vaxtracker is an innovative online active surveillance system that allows people to report how their child, or themselves, have responded to a recently administered vaccine, by completing a web-based survey.

The project began in the Hunter New England Local Health District (HNELHD) in 2011 to monitor the introduction of the seasonal influenza vaccine in young children.

The Vaxtracker project is led by Patrick Cashman at HNELHD, and the Vaxtracker system is developed and maintained by Flexis Systems.

Vaxtracker provides information to the AusVaxSafety network.  AusVaxSafety is part of the National Centre for Immunisation, Research and Surveillance (NCIRS) and is funded by the Australia Government Department of Health.  AusVaxSafety vaccine safety data is available at

In 2014-16, we were able to demonstrate that the influenza vaccines registered and recommended for use in children under five years of age were safe.  Ongoing safety monitoring of vaccines in Australia provides evidence and reassurance for consumers and medical professionals.

Vaxtracker is monitoring vaccine safety in the NSW School Immunisation Program from 2019 onwards.

Participation is entirely voluntary and all individual information remains confidential.  If you have any questions about Vaxtracker please call 1300 066 055, or email
