The federal treasurer says Australia’s planned COVID-19 vaccine rollout is still on track.

Several European countries say supplies of the Pfizer/BioNTech vaccine have fallen short of their orders.

The Australian Government has ordered the Pfizer/BioNTech vaccine from overseas, rather than produce it in Australia. A different vaccine produced by AstraZeneca will be made onshore.

Pfizer has caused concern by temporarily slowing supplies to Europe to make manufacturing changes aimed at boosting output.

Treasurer Josh Frydenberg says it will not affect the plan to roll out jabs next month.

“We have the virus under control here in Australia, but we do want to roll out the vaccine,” he told reporters on Sunday.

“The TGA is going through its normal process but we're still on track to receive the vaccines in mid to late February, I'm advised.”

The statement was intended to clear up confusion caused by Prime Minister Scott Morrison, who had earlier stated that the timing of the rollout “will obviously change and be subject to any impacts on production schedules overseas”.

The Federal Government has also confirmed that when the COVID-19 vaccine is rolled out in Australia, it will be bulk billed.

The Pfizer jab will be delivered in hospitals and specialised hubs as it needs to be kept cold before it is used, while the AstraZeneca vaccine is expected to be administered in GP clinics.
