Effective immediately, Victorians over the age of 18 will now be eligible to get their third dose of the Covid-19 vaccine after three months – instead of four.

Premier Daniel Andrews announced the news in a press conference on Wednesday morning, in line with advice from the public health team.

“This is a big push,” he said in a statement. “Thousands of appointments are available, walk-in capacity has been expanded, opening hours have been extended and more vaccinators will be on the floor.

There’ll be a four-day vaccination “blitz” starting this Friday, where walk-ins will be encouraged at several state-run centres. That includes the Royal Exhibition Building (walk-in from 8am to 8pm), Latrobe University Bundoora (walk-in from 8am to 8pm), Sandown Racecourse (walk-in from 9am to 6.30pm Saturday and Sunday), Dandenong Plaza (walk-in from 9am to 5pm Saturday and Sunday), Frankston’s Bayside Centre (walk-in from 9.30am to 5pm Saturday and Sunday), Sunshine Hospital (walk-in from 8am to 8pm), Bendigo Vaccination Hub (walk-in from 9am to 8pm) and Ballarat Mercure (walk-in from 8.30am to 3pm on Sunday).

“If you got your second dose in October or earlier, now’s the time to come along to one of our major state-run centres this weekend and get your third, to protect yourself and the community for the busy year ahead,” Andrews also said.

The news comes as Victoria records 20,769 new cases of coronavirus, bringing the state’s total number of active cases to 253,827.
