COVID-19 Vaccine Updates in Australia

The Australian Government entered into 4 separate agreements for the supply of COVID-19 vaccines, conditional on evaluations undertaken into their safety, quality and efficacy. (CSL announced the closure of trials into the University of Queensland vaccine in early December due to vaccine interference in HIV diagnostic tests). As other pharmaceutical companies provide updates to their vaccine trials, we will add a summary of the information to this page.

Do we have a COVID-19 vaccine in Australia?

ON Jan 25, 2021 the Therapeutics Goods Administration (TGA) granted provisional approval for the Pfizer mRNA vaccine, Comirnaty, for use in individuals 16 years of age and older. Read more. The TGA is continuing to review preliminary data from trials of COVID-19 Vaccine AstraZeneca (formerly AZD1222). It remains important to maintain the recommended precautions needed to prevent spread of the coronavirus: hand washing/ hand sanitiser, physical distancing and the wearing of masks if this is difficult to achieve, cough etiquette and prompt testing of respiratory symptoms.

When are the first vaccinations to commence?

Subject to supply, the federal government is set to roll out vaccinations of the Pfizer vaccine in mid- to late-February, starting with phase 1a, as outlined in the national strategy announced on Jan 7, 2021.

How Many COVID-19 Vaccines Are Being Developed & Tracked Globally?

The World Health Organization (WHO) is currently tracking the vaccine development of around 170 candidate vaccines globally and they are in various stages of progress – from a pre-clinical phase to large-scale human trials. If a coronavirus vaccine trial results prove successful, the sponsoring company can formally apply to regulatory bodies to have their vaccine approved for use in the general public.

COVID-19 Vaccine Timeline Phases

The pathway to developing a successful vaccine follows several stages - not all may apply: Pre-clinical testing, Phase 1, 2 and 3 trials – sometimes a combination of 2 phases, early approval or emergency use only, approval granted by each country’s regulators, post-approval surveillance, and of course a pause in a trial in response to a concern over a side effect or safety issue.

Research & Testing

Unprecedented international scientific cooperation geared towards a single topic, the SARS Coronavirus-2, has boosted vaccine research which built on work started in response to the SARS outbreak in 2002-3. This has meant a faster vaccine development process than the usual, which can take years or even decades without always resulting in an approved therapeutic. The Australian government is ‘supporting world-leading research activities to speed up the development and manufacture of COVID-19 vaccines and treatments’. Read more from the Australian Dept. of Health and the WHO COVID-19 R&D Blueprint.

Phase 1

Prior to entering into Phase 1 clinical trials, a vaccine first undergoes a pre-clinical assessment or exploratory studies with a fractional dose given to a very limited group of people. Once this stage is successfully passed, a small number of healthy adults are given the vaccine in different dosages (to find a safe dosage range) and subsequently tested for an immune response and checked for any safety issues. Read more

Phase 2

The trial is expanded to a much larger and more diverse group of people – from a wider age range – to test how well it performed under controlled conditions, assessing the immune response to the vaccine, and for further evaluation of what could be any more common side effects, plus any safety issues. Read more

Phase 3

There can be many thousands of people in Phase 3 trials which are undertaken in the community. Volunteers are either given the trial vaccine or a placebo and a successful outcome is hinged on fewer people in the vaccine group becoming infected than the placebo group. During this trial, more uncommon side effects may also become apparent. This phase is followed by each country’s regulatory approval process and post-approval surveillance. Read more 

Early Approval

The TGA has been reviewing preliminary data from the various vaccine trials while also working in cooperation with international counterparts to ensure that information on clinical trials, manufacturing and safety is shared, allowing a speedy but safe regulatory process for Australia and our region. 

Approval

In Australia, the approval of vaccines is undertaken by the TGA  from advice provided by the Advisory Committee on Vaccines, an independent committee composed of members with expertise in science, medicine and public health. The TGA also oversees the quality of each batch of vaccine for distribution in Australia. Read more   

Facts About COVID-19 Vaccinations

The job of these vaccines is to imitate the SARS-CoV-2 virus (which causes the disease COVID-19), prompting a person’s immune system to produce antibodies which can fight the coronavirus. The most novel of vaccines are the mRNA vaccines, where genetically engineered pieces of the virus mRNA (such as the piece that codes for spike protein) are injected and taken up by muscle cells which then use this genetic material to generate the spike protein, so that our immune system can very rapidly generate an immune response including the production of antibodies. These antibodies will be produced by the body if it ever is threatened by the virus. No mRNA vaccine has yet been licenced for use

COVID-19 Vaccine Composition

Rigorous testing ensures that all components of any vaccine are as safe as possible while also producing the best possible immune response. These include some form of the antigen, adjuvants which enhance the actions of the vaccines to produce antibodies, plus stabilisers and preservatives that ensure vaccine potency from manufacture to when it is finally given to someone. In Australia, the Therapeutic Goods Administration (TGA) will assess and grant approval for any vaccines to be used once their safety, quality and effectiveness is proven. More on vaccine composition from the WHO.

Resistance to Vaccination Treatment

There was some early resistance to the idea of rapidly developed vaccines for COVID-19, at least here in Australia, which mainly centred on whether they would be safe. A poll commissioned by the ABC in late September revealed that of the 2,000+ respondents asked whether they would have a vaccine when it became available, only 12 percent said they were either very or somewhat unlikely to do so. More results emerging from vaccine trials showing high levels of protection with minimal side effects may well prove to be reassuring for most of us and pave the way for protective herd immunity.

Vaccine Distribution Strategy & Plan

On Jan 7, 2021, the federal government published Australia's COVID-19 vaccine national roll-out strategy which provides details on the prioritisation of different groups for vaccination against COVID-19. Quarantine and border workers, frontline health care worker sub-groups, aged care and disability care staff and aged care and disability care residents are those in the first, phase 1a of the roll-out. 

Possible Vaccine Side Effects & Reactions

Vaccines are like any medication in that they can cause side effects – the most common are usually mild and include a low-grade fever, headache, fatigue or pain or redness at the injection site which all settle within a few days without treatment. Allergic reactions to vaccines are minimised through pre-vaccination screening while severe or long-lasting side effects are extremely rare. Every vaccine is continually monitored by the TGA to ensure ‘acceptable safety, efficacy/performance and quality for its intended use’.

Types of COVID-19 Vaccines

More on the four types of COVID-19 vaccines (Whole virus, Protein subunit, Nucleic and Viral vector) and how they work from GAVI, the Vaccine Alliance.

The Australian government has agreements for 4 different vaccines, conditional on TGA approval. All are expected to be administered in a 2-dose schedule.

  • AstraZeneca/University of Oxford - AZD1222 Viral vector vaccine (COVID-19 VACCINE ASTRAZENECA)       
  • Pfizer/BioNTech - BNT162b2 mRNA-based vaccine (COMIRNATY)
  • Novavax - NVX-CoV2373 Protein vaccine
  • (University of Queensland/CSL - V451 Protein subunit vaccine trial halted in Dec 2020 Read more)

Another 7 vaccines are included in the COVAX facility, which is a global effort to support fair access to COVID-19 vaccines for all countries. Aust. Dept. of Health

More will be known about the recommended age groups and any potential side effects as results of human trials are published.

Frequently Asked Questions (FAQs)

FAQs

Why do we need a vaccine?

Prevention is always better than cure, particularly as we still lack therapeutics known to effectively treat COVID-19 in all its phases. An effective vaccine will enable international travel to be re-established with significantly reduced risk of disease transmission.

When will a vaccine be released in Australia?

The first COVID-19 vaccine, Pfizer's Comirnaty, was approved in Australia on Jan 25, 2021 with TGA reviews continuing into the remaining vaccine candidates. Read more

How much would vaccines cost?

The Australian government will be providing COVID-19 vaccines free of charge for citizens and eligible residents, with the medical consultation for administration of the AstraZeneca vaccine (once approved) to be provided in a bulk bill visit at participating GP clinics. Read more 

How many doses of COVID-19 vaccine will be needed?

Most of the vaccines currently in phase 3 trials require 2 doses of vaccine 3 - 4 weeks apart. 

Who will receive vaccination first?

The target populations in the initial phases of vaccine roll-out are those considered at a higher risk of COVID-19 disease or its potential outcomes, such as key workers in border control and quarantine, as well as those in healthcare and aged care. For further information see Australia's COVID-19 vaccine national roll-out strategy.   

Would vaccines be effective in protecting everyone?

We must wait for the results of human clinical trials which are underway to know the details of vaccine efficacy across different groups of people.

These vaccines have been developed very quickly so are they safe?

Coronavirus vaccine research had started in response to the SARS outbreak in 2002 and while some progress had been made, once the outbreak ended in 2003 funding slowed and only very limited research continued. Now, unprecedented international scientific cooperation has boosted vaccine development and newer platforms now offer different types of vaccines. Testing of vaccine safety continues throughout the manufacturing process and the bottom line is that the risk of having a severe outcome from COVID-19 far outweighs any theoretical risk of a vaccine.

The vaccines which are being developed have had tens of thousands of people in their trials, world-wide totalling nearly one quarter of a million people, providing researchers with a much larger amount of data than for many other vaccines routinely used.

Can I get a COVID-19 earlier through the private system?

COVID-19 vaccines will be free for all Australian citizens, permanent residents and most visa-holders.

Early supplies are expected to be limited and, as per the Australian Vaccination policy , priority groups will be offered the vaccines first at designated vaccination sites. Where these vaccines may be administered will vary from state/territory but is likely to include hospital-based clinics for hospital staff and other workplaces, including aged care facilities.

Once more supplies become available, vaccines will be available to the broader population through usual immunisation providers, such as general practice clinics and general practice respiratory clinics.

It is possible that some vaccine candidates may eventually become available on the private market, meaning they will not be free of charge such as those which will be provided to eligible Medicare card holders in Australia. More information will be forthcoming as the different vaccines are granted approval and supplies are assured.

Glossary of terms

Herd immunity: Protection against a disease either through immunity gained from having the infection (with the inherent risk of severe illness, long-last effects or even mortality) or receiving a vaccine. When the majority of people are immune, it is much less likely that the disease will spread as there are so few susceptible people left to infect. These susceptible people may not be able to have a vaccine either due to their age (too young or too old) and immune deficiencies (i.e. cancer or autoimmune disease).

Efficacy vs effectiveness: Efficacy is measured during a vaccine trial when all conditions are ideal and strictly controlled, whereas effectiveness is determined on how well a vaccine performs when used under normal, real-life situations.
