Pharmaceutical company Moderna says it has done a deal with the Australian government to provide 25 million doses of its COVID-19 vaccine to the nation.

The announcement came in a Wednesday evening media statement without any adjoining statement from the federal government, which has recently been under fire over Australia's vaccine rollout.

Moderna said it would provide 25 million doses of their mRNA vaccine, with 10 million of those doses, effective against what they labelled the "ancestral strain" of COVID-19, to arrive in 2021.

The company said another 15 million doses will be delivered to Australia in 2022 and they will be of what Moderna called an "updated variant booster candidate vaccine".

Those deals are subject to regulatory approval from Australia's Therapeutic Goods Administration, which Moderna said it would submit an application to "shortly".

If that is successful then Moderna would join both AstraZeneca and Pfizer as vaccines approved for use to Australians.

Australia also has a deal in place with Novavax, who's vaccine is in the trial phase.

Moderna said it would discuss the notion of producing the vaccine locally with the Australian government.

"We appreciate the partnership and support from the government of Australia with this first supply agreement for doses of the Moderna COVID-19 vaccine and our variant booster candidates," Stephane Bancel, Chief Executive Officer of Moderna, said in a statement.

"As we seek to protect people around the world with our COVID-19 vaccine and potentially our variant booster candidates, we look forward to continuing discussions with Australia about establishing potential local manufacturing opportunities."

One of those options could be in South Australia, where international company BioCina say they can produce mRNA vaccines, but would need government support.

The government recently secured more doses of the Pfizer vaccine after their planned rollout, which heavily relied on the AstraZeneca vaccine, was thrown into chaos due to fears about rare cases of blood-clotting in people under 50 years of age.

The government then altered their plan based on medical advice and revoked the rollout of the AstraZeneca vaccine to Australians under the age of 50.

The AstraZeneca vaccine is still being rolled out to people over the age of 50 and in the last week more than 400,000 Australians received shots.

The total number of doses delivered is now edging towards 2.7 million.

On Monday Health Minister Greg Hunt said that while he was encouraged by more Australians being vaccinated he would not set any new targets for the speed of Australia's rollout.
