Pfizer covid-19 vaccine

Australia's medical regulator has approved the Pfizer/BioNTech COVID-19 vaccine for use under a formal process, one of the first countries to complete a comprehensive approval, Prime Minister Scott Morrison said on Monday.

The vaccine had been provisionally approved by the Therapeutic Goods Administration's (TGA) for Australians aged 16 years and over, Morrison told reporters, noting it was a year since the first coronavirus case was detected in the country.

Vaccination of priority groups is expected to begin in late February, at 80,000 doses per week, Health Minister Greg Hunt told reporters.

Two doses will be required – at least 21 days apart, a government statement said. Australia will administer both doses of the vaccine at the recommended time.

"You don't start what you can't finish, and finishing the job involves two doses," said Morrison, adding a digital system would ensure people get two doses.

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.

He cautioned there are limitations to what the vaccines can do and that the rollout would not mean border restrictions would be lifted.

Quarantine and border personnel, frontline health workers, aged care and disability staff and residents will be the first group to receive vaccines.

Australia expects to have the capacity to produce the AstraZeneca vaccine onshore starting late March.

"I welcome the TGA's approval of the Pfizer vaccine, with our own Australian experts finding it is safe, effective and of a high standard," Morrison said in a statement.
