The Therapeutic Goods Administration (TGA) is responsible for monitoring the safety of all vaccines approved for use in Australia. We closely assess safety data prior to approval, and continue to monitor the safety of vaccines after they are registered in Australia so that we can detect and respond to any safety concerns. This is known as 'pharmacovigilance'.
Understand potential side effects from COVID-19 vaccines
Like other medicines, all vaccines can cause side effects. Most side effects are mild and temporary (lasting 1 or 2 days). Common side effects include low-level fever and pain or redness where the injection was given.
Even when the suspected side effect is serious, it is possible - even likely - that it may not have been caused by the vaccine. The timing may be coincidental. There is an expected 'background rate' of coincidental adverse events. This is why the TGA investigates the reports it receives to determine if there is a genuine safety concern related to the vaccine.
If you have any questions or concerns about potential side effects of COVID-19 vaccines, please speak to your doctor.
The TGA's safety monitoring processes for vaccines are robust and well established. They include collaboration with Australian stakeholders, including state and territory health departments and professional bodies, and international regulators. This enables us to rapidly detect, investigate and respond to any emerging safety issues.
