Australia’s active vaccine safety system


AusVaxSafety is conducting active vaccine safety surveillance of the COVID-19 vaccines in use in Australia to ensure their ongoing safety. The COVID-19 vaccines currently being used are Comirnaty (Pfizer), Vaxzevria (AstraZeneca), Spikevax (Moderna) and Nuvaxovid (Novavax). AusVaxSafety is currently reporting safety data on Pfizer, AstraZeneca, Moderna and Novavax COVID-19 vaccines.


AusVaxSafety moving to fortnightly reporting of COVID-19 vaccine safety data

AusVaxSafety has been reporting COVID-19 vaccine safety surveillance data weekly since the vaccination program commenced on 22 February 2021. More than 2.5 million Australians have participated in this surveillance, by completing more than 6.3 million safety surveys, outlining their experience following their COVID-19 vaccination. As a result of this high level of participation, we now have an unprecedented amount of safety data, specific to Australia, on short-term adverse events following vaccination (AEFI). To date, the AEFI data reported are consistent with those seen in clinical trials and surveillance in other countries, reaffirming the safety of COVID-19 vaccines in use in Australia.

The safety data received from the 6.3 million survey responses have remained very stable over this time, with minimal change to the safety profile of the vaccines. As a result, AusVaxSafety will now be updating COVID-19 vaccine safety data on a fortnightly basis, instead of weekly, on this page. The next update will occur on Wednesday 18 May 2022.

The AusVaxSafety team will continue to regularly review data received on an ongoing basis to ensure there are no new safety concerns.
