Australia’s trusted independent immunisation experts


In response to the COVID-19 pandemic, our policy support team has been closely monitoring publicly available information on COVID-19 vaccine candidates. We have used information from international platforms, including the World Health Organization (WHO) and the Coalition of Epidemic Preparedness and Innovations (CEPI), national regulatory institutes, clinical trial registries, vaccine developers and manufacturers, and scientific literature to develop the content on this page. Our focus is to understand the current state of development of COVID-19 vaccines and clinical trials. We will be updating this page weekly.

Figures are based on the WHO document Draft landscape of COVID-19 candidate vaccines and monitoring of clinical trials registries.

  • COVID-19 vaccines in phase III clinical trials globally

    Candidate vaccines must be tested in preclinical, phase I, phase II, phase III clinical trials before they are licensed and available to the public. For further explanation, refer to Phases of clinical trials page. Traditionally it takes at least 10 years from development to licensure of a vaccine. The pandemic has pushed for an accelerated approach to vaccine development. Several candidate vaccines have moved into the next stage of clinical trials before completion of earlier stage trials.  

    There are several vaccine platforms that are being used for the development of COVID-19 vaccines. These include long-established technologies such as live attenuated virus/ inactivated virus and protein vaccines. More modern methods such as viral vector vaccines and nucleic acid vaccines are also being used to develop COVID-19 vaccines. Refer to Vaccine platforms page for an explanation of different vaccine platforms. 

    Below are candidate vaccines that are currently in phase III clinical trials only. For a full list of COVID-19 candidates in clinical trials, check out the WHO Draft landscape of COVID-19 candidate vaccines and the London School of Hygiene and Tropical Medicine COVID-19 vaccine tracker.

    * The Therapeutics Goods Administration (TGA) has given provisional determination to three vaccine candidates. These candidates are now eligible to apply for provisional registration of their vaccine in the Australian Register of Therapeutic Goods (ARTG).

  • COVID-19 vaccines in clinical trials in Australia

    There are currently six COVID-19 vaccines in human clinical trials in Australia.

    Two candidates, Covax-2019 (Vaxine) and SARS-CoV-2 S clamp u451 (University of Queensland), are being developed and trialled in Australia. The u451 vaccine will not proceed to phase III clinical trials because the clamp protein (being derived from the HIV virus) has the potential to interfere with some HIV screening tests and can lead to a false positive test result in vaccine recipients.

    The other four candidates are being developed in countries outside of Australia: the SCB-2019 candidate by Clover Biopharmaceuticals is developed in China, the NVX-CoV2373 candidate by Novavax is developed in the United States, the RBD-SARS-CoV-2 HBsAg VLP vaccine by SpyBiotech is developed in the United Kingdom (and has a partnership with the Serum institute of India) and the bacTRL-Spike vaccine by Symvivo is developed in Canada.

    Novavax published phase 1 results in the New England Journal of Medicine on 2 September 2020. 

    At the end of September, the Australian Government pledged almost $6 million in additional funding from the Medical Research Future Fund’s (MRFF) Coronavirus Research Response to support research and development of three Australian COVID-19 vaccines. For further information on COVID-19 vaccine development in Australia, click here and for further information on the phase I/Ib human trial, click here.

    • COVID-19 vaccine development in Australia

      Several COVID-19 candidate vaccines are being developed in Australia. Two candidates have entered into phase I clinical trials and others are currently in laboratory and pre-clinical stages. The following information is from publicly available data and may not include all candidates in development in Australia.

    • COVID-19 vaccine introduction and program planning in Australia
      Therapeutic Goods Administration

      The Therapeutic Goods Administration (TGA) has given provisional determination to three vaccine candidates: 

      This means that these companies are now eligible to apply for provisional registration of their vaccine in the Australian Register of Therapeutic Goods (ARTG). However, these companies have not yet made any application to be registered for use in the ARTG. 

      Provisional determination is the first step, before provisional registration.

      Commonwealth Government COVID-19 Vaccine Taskforce

      The COVID-19 Vaccine Taskforce is working with the Australian Technical Advisory Group on Immunisation (ATAGI) COVID-19 Working Group, the TGA as well as local and international vaccine manufacturers for access to and delivery of safe and effective COVID-19 vaccines for all Australians. 

      COVID-19 vaccines will and must be evaluated for safety and effectiveness before they are registered for use in Australia. Strategic planning on the COVID-19 vaccine program implementation, safety monitoring and communication is underway. 

      COVID-19 vaccines and treatments

      There is currently no specific treatment or approved vaccine that cures or prevents COVID-19. Researchers and companies across the world are developing potential vaccines and treatments, and the Australian Government has a strategy to deliver them to Australians.

      COVID-19 vaccines: Frequently asked questions

      Visit our COVID-19 vaccines: Frequently asked questions web page to find answers to some commonly asked questions about COVID-19 vaccines.

    Vaccines must go through several phases of clinical trials before they can enter the market. Not all vaccines that enter the initial phases of clinical trials make it to the market. Visit our Phases of clinical trials page to learn more.

    Different platforms are used to develop viral vaccines. Each of these platforms has its own advantages and disadvantages. Visit our Vaccine platforms page to learn more.

    Note: NCIRS checks clinical trial registries, particularly the U.S. National Institutes of Health, National Library of Medicine: Clinical Trials Gov, EU Clinical Trials Register, ISRCTN, Cochrane COVID-19 Study Register, Clinical Trials Registry – India,  Australian New Zealand Clinical Trials Registry, Chinese Clinical Trial Registry on a regular basis to monitor the commencement of clinical trials.
