Australia's second-largest city Melbourne went into a 6th lockdown on Thursday, with a state government leader blaming the nation's slow COVID-19 vaccination rollout for the decision.

Melbourne joins Sydney and Brisbane, Australia's most populous and third-most populous cities respectively, in locking down due to the spread of the highly contagious delta variant.

Melbourne and surrounding Victoria state will lock down for seven weeks after eight new infections were detected in the city, Victoria Premier Daniel Andrews said.

Andrews gave less than four hours notice that the state would lock down from 8 p.m. local time. He said his government had no other choice because only 20 percent of Australian adults had been fully vaccinated by Wednesday.

COVID-19 Vaccine

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

“To be really frank, we don't have enough people that have been vaccinated and, therefore, this is the only option available to us,” Andrews said. “The time will come when we have many more options. But that isn't now.”

Andrews has accused neighbouring New South Wales state of taking too long to lock down Sydney after a limousine driver who became infected while transporting a US aircrew from Sydney Airport tested positive to the delta variant on June 16.

New South Wales on Thursday reported its worse day since the Sydney lockdown began on June 26 with a record 262 new local infections and five deaths.

New South Wales Premier Gladys Berejiklian said four of the dead had not been vaccinated. One had had a single dose of the two-shot AstraZeneca vaccine in late May.

Australian authorities have urged people in Sydney not to wait the optimal 12 weeks before taking their second AstraZeneca dose.

“No one who has died has had both doses of vaccine. I cannot stress enough how it's so important for everybody of all ages to come forward and get the vaccine,” Berejiklian said.

AstraZeneca and Pfizer are the only vaccines available in Australia.

There have been 21 COVID-19 deaths in Sydney since the latest outbreak began. There have been 78 deaths in New South Wales since the pandemic began.

The government reported 262 locally acquired infections in the latest 24-hour period. Another six cases were diagnosed in hotel quarantine and are not considered threats to the community.

When Victoria ended its fifth lockdown last week, Andrews said he believed the state was the only jurisdiction in the world that had beaten a delta outbreak twice.

Melbourne was the Australian epicenter of the pandemic last year, when new infections peaked at 725 in a day in August. Of Australia's 925 COVID-19 deaths since the pandemic began, 820 have occurred in Victoria.

Authorities were gaining confidence on Thursday that a lockdown of Brisbane and surrounding cities in Queensland state will end an eight-day lockdown as planned on Sunday.

Queensland Chief Health Officer Jeannette Young said efforts to suppress the spread had surpassed expectations.

All 16 new locally acquired cases reported on Thursday have been directly linked to known exposure sites.

But doubts are growing that Sydney's lockdown will end as planned on Aug. 28 as case numbers continue to grow.
