Victoria confirmed 45 newly acquired cases of COVID-19 on Wednesday, including nine mystery cases and 28 in the community while infectious.

On Tuesday, more than 53,000 Victorians showed up to get tested, and 31,600 vaccination doses were administered.

The rush for vaccinations caused Victoria’s Health Department’s online booking service to have slow loading times and be crushed by the high demand as people were stuck waiting in an online queue.

Those who tried to book on the phone abandoned their calls due to the long waiting times.

From today, a million Victorian teenagers over the age of 16 will be eligible for the Pfizer jab.

Victoria’s government threw open more than 830,000 new first-dose appointments at state-run facilities, and these include 450,000 Pfizer shots which will be given to anyone from the ages of 16-39 even though they may not be part of a priority group.

Though the lockdown is not expected to end on 2 September as scheduled, it is hoped that contact tracers will be able to control the latest outbreak with daily cases not needing to be in single digits for this to happen.

There are fears that the state could face strict restrictions until around 70 per cent of the adult vaccination is fully vaccinated.

NSW is also expected to unveil eased restrictions for fully vaccinated residents having administered vaccinations to 60 per cent of the population.
