Calls to overhaul Victoria's vaccine booking system after 'hundreds' of no-shows

There are calls for an overhaul of Victoria's COVID-19 vaccine booking system after some centres registered hundreds of cancellations.

No-show rates, where a vaccination is booked but nobody attends, are on the rise across Melbourne and could be slowing down the rollout.

However the uptick in cancellations is unlikely to mean the vaccines will go to waste, as they are drawn out of the vials when people arrive.

Emergency Physician Dr Stephen Parnis said other countries would not miss their opportunity to get vaccinated if it arose.

"These vaccines are liquid gold," Dr Parnis said.

"There are parts of the world that would sell their soul for access to our two safe vaccines. If you've got an appointment go and get it."

Victorian opposition spokesman David Southwick said a piece of technology which allowed eligible people to take the place of no-shows is needed.

"We simply need a better approach to this," Dr Southwick said.

"We know if you book a restaurant and you no-show, other people on the waiting list will get a text. Why can't the government have a similar system?"

Wastage at state-run vaccination clinics in Victoria is less than one per cent.

As at midnight last night, more than 10 million doses of the vaccine had been administered in Australia.

More than three quarters of people aged over 70 are now protected while more than 59 per cent of those aged over 50 are now protected.
