Novavax, a protein-based substitute for mRNA vaccines, has become a major factor in Australia’s immunisation policy as the global fight against COVID-19 rages on. Novavax has introduced NuvaxovidTM, a vaccine that has received provisional approval from the Therapeutic Goods Administration (TGA) for a range of age groups and uses, through its collaboration with Biocelect Pty Ltd.
The Novavax Approach: Protein-Based Vaccine Technology
Unlike mRNA vaccines, Novavax’s Nuvaxovid™ employs a recombinant protein-based nanoparticle technology combined with the Matrix-M™ adjuvant. This approach presents the immune system with a harmless version of the spike protein found on the surface of the SARS-CoV-2 virus, prompting an immune response without using live virus components. The Matrix-M™ adjuvant, derived from the bark of the Quillaja saponaria tree, enhances this immune response, aiming to provide robust protection against COVID-19 .Health.gov.au+3Novavax+3Novavax Investor Relations | Novavax+3
Regulatory Milestones in Australia

- June 2022: Provisional registration was extended to include its use as a booster dose for individuals aged 18 and over, regardless of their initial vaccine type .Novavax Investor Relations | Novavax
- July 2022: The TGA further expanded approval to adolescents aged 12 through 17, based on clinical trial data demonstrating safety and efficacy in this age group .Novavax Investor Relations | Novavax
Clinical Trials and Efficacy
Australia has played a significant role in the clinical evaluation of Nuvaxovid™, with nearly 1,500 Australians participating in various trials. These studies have contributed to the global understanding of the vaccine’s safety and effectiveness. In Phase 3 trials conducted in the U.S. and Mexico, Nuvaxovid™ demonstrated approximately 90% efficacy in preventing symptomatic COVID-19, showcasing its potential as a vital tool in the pandemic response .Novavax Investor Relations | Novavax
Addressing Vaccine Hesitancy
The introduction of a protein-based vaccine like Nuvaxovid™ offers an alternative for individuals hesitant about mRNA vaccines. This option has been particularly appealing to those seeking a more traditional vaccine platform, potentially increasing overall vaccination rates and contributing to broader community protection .Health.gov.au+1Novavax Investor Relations | Novavax+1Health.gov.au
Ongoing Developments and Future Outlook
Novavax continues to engage with regulatory authorities to expand the use of Nuvaxovid™. In the United States, the Food and Drug Administration (FDA) has requested additional clinical trials to further assess the vaccine’s efficacy, indicating a commitment to thorough evaluation despite existing approvals in countries like Australia, Europe, and Japan .WSJ
In Australia, Novavax’s presence is bolstered by its partnership with Biocelect Pty Ltd, ensuring the distribution and availability of Nuvaxovid™ across the country. This collaboration underscores Novavax’s dedication to providing diverse vaccine options to meet public health needs.
