Hepatitis C is one of the most common notifiable infectious diseases in Australia with 200,000 infected individuals and 10,000 new infections each year. Treatments currently available for hepatitis C are effective but also associated with significant side effects and expensive.

$642,792.00
Summary
There is no Zika vaccine and only one licensed dengue vaccine, which is age and region restricted because of poor efficacy. We have developed safe subunit vaccine candidates capable of inducing potent virus neutralizing antibodies and demonstrated protection from lethal dengue challenge in a mouse model. Here we are partnering with Vaxxas to undertake preclinical development and GLP toxicity trials for microarray patches delivering dengue and zika virus subunit vaccines.
A Universal Prophylactic Vaccine For Hepatitis C Virus

Funding Amount
$643,337.00
Summary
Hepatitis C Virus (HCV) infects 200 million people world wide. An effective vaccine to prevent HCV is urgently needed but must afford protection against the 7 diverse genotypes. In this project grant we aim to further define the quality of the immune response that is generated by a novel HCV vaccine candidate that generates pan-genotypic immunity, its unique structural features, and methods of manufacturing so that it can be tested in a future phase I human clinical trial.
Protecting Australia From Future Swine Flu Pandemics-Functional And Structural Studies Of The H1N1 Swine Influenza A Surface Glycoprotein Hemagglutinin

Funding Amount
$401,361.00
Summary
The severity of the present and future pandemic strains of the swine flu will depend on the ability to contain and combat infection via pre-emptive development of appropriate vaccines and drugs. To this end, my study of the surface glycoprotein hemagglutinin, will help predict and prevent future swine influenza pandemics by identifying potentially pandemic strains to be targeted for early vaccine development.
Prophylactic Vaccine Development For The Elimination Of Hepatitis C

Funding Amount
$936,752.00
Summary
A vaccine that prevents Hepatitis C is urgently needed to prevent infection and assist with global HCV elimination targets. This project grant will advance world-leading HCV vaccine candidates that generate both humoral and cellular immunity for clinical development.
Novel Generic Vaccine Approaches Applied For The Prevention Of Hepatitis C And Influenza Virus Infections.

Summary
For the induction of good immune responses, antigens should be delivered in several copies on a defined particle. The small envelope protein (HBsAg) encoded by the hepatitis B virus (HBV) has the capacity to self-assemble with host derived lipids into VLPs. HBsAg VLPs are the sole component of one of the most successful vaccines, and clinical trials have shown that they are a successful delivery system for foreign epitopes or protein domains.

The small envelope protein (HBsAg) encoded by the hepatitis B virus (HBV) has the capacity to self-assemble with host derived lipids into VLPs. HBsAg VLPs are the sole component of one of the most successful vaccines, and clinical trials have shown that they are a successful delivery system for foreign epitopes or protein domains. Hepatitis C virus (HCV) and Influenza viruses are major human pathogens. HCV has infected 200 million people worldwide, and there is no effective vaccine available. Influenza continues to affect thousands of people each year causing epidemics with severe morbidity and considerable mortality. Current influenza vaccines are mostly inactivated formulations and they exhibit poor immunogenicity in immunological naive persons such as children and in the elderly. The influenza vaccines are not optimal for stimulation of cell-mediated immunity. We propose to use particulate antigens as a delivery platform for influenza and HCV-specific epitopes with the focus to develop approaches to target various HCV and influenza strains, including H5N1 bird influenza. We have successfully produced modified VLPs containing HCV-specific sequences, which are able to induce anti-HCV antibodies with neutralising capacity. We hypothesise that the design of VLPs with an appropriate set of HCV-specific antigens will enhance the neutralising capacity of anti-HCV sera and this may overcome strain specificity. This application will exploit a prototype delivery system to induce antibody and also cellular responses against a variety of HCV- and influenza specific target sequences (epitopes). The outcome of this study will be a prototype multivalent vaccine to a range of HCV- and influenza-specific epitopes. As a delivery system this will be ideal for vaccination against agents that are highly variable.Read moreRead less
A Novel Vaccine Platform For Trimeric Envelope Proteins: HIV-1 Envelope

Summary
Vaccines are urgently needed for the prevention of HIV/AIDS. The design of this vaccine candidate is based on the display of HIV-1 envelope spikes using a related primate retrovirus envelope with a more stable assembly to anchor the the spikes in a particle.
Roles Of The Hepatitis C Virus Glycoprotein E2 Variable Regions In Virus Entry, Immunogenicity And Immune Evasion.

National Health and Medical Research Council
Funding Amount
$682,820.00
Summary
Hepatitis C Virus infects 200 million people world-wide with over 200,000 Australians infected with the disease. This project will examine how the surface proteins of HCV change their shape to evade antibody responses and how this effects the outcome of infection. We will further characterize a vaccine that elicits protective immunity to HCV to identify the optimal formulation for clinical trials.
CLINICAL RESEARCH TO UNDERSTAND ACQUIRED IMMUNITY TO DENGUE VIRUSES

Funding Amount

Summary
Dengue, the commonest arboviral disease of humans, is caused by any of the four serotypes of dengue virus (DENV-1-4). This clinical research project will explore how acquired immunity to dengue viruses is expressed. The results will help dengue vaccine developers make better vaccines for use in Australian travellers and in dengue endemic countries in SE Asia.
