Western Australia Vaccine Safety Surveillance (WAVSS) System

The WAVSS reporting system is now part of the national reporting hub called Adverse Events Following Immunisation – Clinical Assessment Network (AEFI-CAN).


The website address has now changed to aefican.org.au which is where WA adverse event reports are to be submitted from now on.


There are no changes to the WAVSS name, services or management.  All Western Australian reports will be followed up as usual by WA Department of Health staff.

The Western Australian Vaccine Safey Surveillance (WAVSS) system is the reporting service in WA for any significant adverse events following immunisations (AEFI).

WAVSS provides expert immunisation safety advice to reporters and healthcare workers, and can provide clinical services for children and adults who have experienced an AEFI.

Adverse Events Following Immunisation (AEFIs)

An AEFI may be due to:

  • A person's response to a vaccine
  • AEFIs also include conditions that may occur following the incorrect handling or administration of a vaccine
  • Coincidence, ie. it would have occurred regardless of vaccination

For more information on what an AEFI is, and when to report one, please refer to the following websites:

Reporting AEFIs

AEFIs may be reported by:

  • Medical and nurse practitioners have a statutory responsibility to notify adverse events following immunisation (AEFI) to the Chief Health Officer, as per the requirements of the Public Health Act 2016 and the Public Health Regulations 2017.
  • Other immunisation providers
  • Parents and guardians
  • Vaccinated individuals

To Report an AEFI

Please go the the Register tab on this website if this is your first time, or the Login tab if you have already registered.

If required, please see Guide to reporting a AEFI for further information.

Other immunisation providers, parents/guardians or vaccinated individuals may also report adverse events.

By getting as much information as we can about AEFI, we make sure we detect possible problems with vaccines or systems as early as possible if they do occur.

This helps to ensure Western Australia has a safe immunisation program and to maintain community confidence in our program.
