In preparation for the move, SA Health is making an additional 60,000 appointment slots available today, ahead of a doubling of capacity at the Wayville vaccination clinic and the opening of a northern suburbs clinic in Pooraka next week.

Pfizer appointments at state-run clinics are also open to over 60s from today.

The rollout expansion comes as South Australia nears 60 per cent of the population over the age of 16 having at least one dose of the vaccine.

As of midnight Saturday, 59.1 per cent of the eligible population has had one dose, while 40,4 per cent is fully vaccinated, according to the latest Federal Government vaccine data.

It comes as South Australia recorded no new cases overnight after another COVID-19 scare over the weekend.

A miner from New South Wales who flew into South Australia on Friday and tested positive on Saturday triggered four exposure sites at Adelaide Airport.

But chief public health officer Nicola Spurrier this morning said 95 per cent of the 40 close contacts associated with the miner have tested negative so far.

“I was very pleased actually that as soon as he came in he was directed to get tested, he went to the Altura to wait for his test result because he needs to isolate,” she told ABC Radio this morning.

“So whilst there were some exposure sites we actually only had about 40 people that we’re considering close contact.

“It all went to plan really.”

South Australia’s rollout is also set to get another boost after The Australian Technical Advisory Group on Immunisation recommended the Moderna vaccine for everyone 12 years and older.

The Therapeutic Goods Administration had previously given provisional approval for Moderna jabs for 12 to 15 year olds.

Assisting this additional demand, Prime Minister Scott Morrison announced the federal government had secured an additional one million Moderna doses from member countries of the European Union.

These will arrive next weekend and will start to be rolled out to the 3600-strong community pharmacy network, kicking off with up to 1800 in the first stage.

National COVID taskforce co-odinator-general John Frewen said that means more than 11 million doses of mRNA will be available in September.

“This will be followed by 12 million doses in October and then 12 million doses in November,” he told reporters in Canberra on Sunday.
