The nation’s vaccination program topped three million on Friday and Prime Minister Scott Morrison believes it is now going from strength to strength, noting even on Saturday a record 30,000 people got the jab.

“If you are over 50, you can go to your GP who are providing these vaccines,” Morrison told reporters in Queensland on Sunday.

“So I think we will continue to see that build.”

He said about 85 per cent of residents in aged care facilities have now been vaccinated, but he urged more people over 70 to get the jab.

“That is a very high priority for us because if there were to be an outbreak in Australia, they are the Australians most at risk and that is where our focus is the most at the moment.”

SA’s deputy chief public health officer Dr Emily Kirkpatrick said GP clinics across the state will start to receive their share of the additional doses within the next two weeks following a recent expression of interest process.

“GPs have been at the forefront of the rollout for their patients and we are pleased to be able to partner with GPs to provide additional doses and increase access for South Australians to the COVID-19 vaccine,” she said.

“In addition to the expanding GP network and availability, SA Health is also pivoting as the rollout progresses which will see some hospital-based clinics transitioning so that clinics in the community can scale up to provide better access and increased capacity.

“South Australians who are eligible for the vaccine now have more access, with the Pfizer vaccine available for those in phases 1a and 1b of the program, and the AstraZeneca vaccine available for anyone aged 50 years and over through the ever-expanding GP and state-run vaccination clinic network.”
