Federal government figures show that as of Saturday, 70.3 per cent of people in South Australia over the age of 16 are fully vaccinated against COVID-19, while 83.7 per cent have received a first dose.

SA Health-commissioned modelling from the University of Adelaide predicts South Australia will reach the 80 per cent double-dose milestone on November 29.

That’s despite significant inequities in the rollout, with several northern suburbs LGAs only projected to be around 60 to 70 per cent double dosed on the November 23 border reopening date, according to modelling from local data scientist Ben Moretti.

Similarly, the latest Indigenous vaccination data for South Australia, correct as of last Tuesday, shows just 40.5 per cent of the state’s Aboriginal population is fully vaccinated.

South Australia’s vaccination rate for children aged between 12 and 15 are also the second-worst in the nation, with 53.5 per cent of the cohort having received one dose and only 28.8 per fully vaccinated.

The national average for vaccination in the 12-15 cohort is more than 52 per cent.

Most COVID-19 restrictions in South Australia are not due to ease until 90 per cent of the over-12s population is fully vaccinated.
