On Thursday evening, the Australian Government made amendments to Australia’s vaccine program based on international evidence linking a rare blood-clotting condition to the AstraZeneca vaccine in younger people, with Pfizer now being the preferred vaccine for people under the age of 50.

The Australian government has chosen not to be definitive in their advice; instead they have left the choice regarding which vaccine should be administered to individual Australians in consultation with their GP. The AstraZeneca vaccine will still be available for people under the age of 50 on a case-by-case basis, with vaccinations of elderly Australians continuing as planned.

As evidenced by these recent changes, providing timely, factual and transparent information – even if this information does not include clear rules or definitive advice – remains paramount in ensuring public trust in the Australian vaccination program.
