Rollout to Vic under-50s set to gain pace

The vaccine rollout to Victorians aged under 50 will gather pace from next week, with priority groups eligible for the Pfizer jab.

Acting Premier James Merlino said the state had the capacity to deliver two to three times the current number of jabs over the next month - depending on supply from the Commonwealth.

From Monday, emergency service workers, defence force personnel, meat industry workers, people with underlying health conditions or severe mental ill-health will be able to get a Pfizer dose.

Disability support workers, unpaid carers and public transport workers will also be eligible.

More vaccination centres are opening, including a centre at Melbourne Showgrounds from Monday.

Victoria has gone three days without any local cases since a Melbourne man was confirmed to have tested positive to COVID-19.

But a further six Victorians may have been exposed to the virus after staying at the same South Australian quarantine hotel where the Melbourne man is suspected of catching COVID-19.

The Department of Health has identified the six as having left the third floor of Adelaide's Playford Hotel during the potential transmission period.

They returned negative tests results on Thursday and are undergoing another two weeks of quarantine.

The Victorian government has confirmed that 135 primary close contacts to the infected man have tested negative, with 14 results pending.

The Acting Premier has said that his understanding is the infected man, from Wollert in Melbourne's north, is not sick.

Meanwhile, the Victorian government is cracking down on businesses flouting QR code check-in rules after the state's latest coronavirus scare exposed flaws in the system.

Contact tracing efforts were hampered this week as some patrons at the Curry Vault restaurant, where the infected Melbourne man dined on Friday night, failed to use the QR code system.

In response, the state government warned businesses breaking check-in rules will face a new $1652 on-the-spot fine, with further penalties of up to $9913 and prosecution for repeated breaches.

Checks last week showed more than a third of businesses are not complying with QR code rules.

Authorities dished out 165 enforcement notices and 300 warnings as part of a three-week blitz of 4000 cafes, shops and restaurants in April.

The breaches included a lack of signage, failing to use QR codes, and not having a COVID-safe plan.

The Services Victoria QR code system will become mandatory for businesses from the end of May.

An average of 28,000 check-ins is being registered on the system every day, with more than 91,000 businesses signing up.

There were 7746 coronavirus vaccine doses in the 24 hours to Friday, for a total of 299,397.
