COVID-19 vaccine weekly safety report #1 - 03-03-2021

The national roll-out of COVID-19 vaccines commenced on 22 February 2021. The vaccine currently being supplied is Comirnaty BNT162b2 (mRNA), sponsored by Pfizer Australia Pty Ltd.

The Therapeutic Goods Administration (TGA) is closely monitoring suspected side effects (also known as adverse events) from the use of the vaccine.

Learn about the TGA’s COVID-19 vaccine safety monitoring and reporting activities or report a suspected side effect.

Total adverse event following immunisation (AEFI) reports received up to 28 February 2021

Gathering reports of suspected side effects following vaccination is just the first step in determining whether or not the effect is related to the vaccine and whether a significant safety issue is involved. Learn more about how the TGA identifies and responds to safety issues.

Active surveillance

AusVaxSafety is an active vaccine safety surveillance system that complements the TGA’s enhanced safety surveillance activities. Active vaccine safety surveillance uses SMS and a short survey to collect reports of AEFI directly from a subset of people receiving the vaccines. AusVaxSafety is an Australian Government-funded system that shares its findings with the TGA to assist our safety investigations and responses.
