Tuberculosis is one of the most threatening infectious diseases worldwide due to the low efficiency of the only licensed anti-tuberculosis vaccine, BCG. This project aims to interrogate two previously neglected immune mechanisms and their potential to enhance vaccine-induced immunity by incorporating these mechanisms into new genetically modified BCG strains. We will also investigate alternative BCG vaccination routes to generate long-lived immune cells that can rapidly control the infection.
Targeting Antigen To Clec9A On Dendritic Cell For Humoral Immunity

Funding Amount
$744,624.00
Summary
Dendritic cells capture infectious organisms and display them to other immune cells to initiate immunity. The process of capturing organisms requires dendritic cells to express a variety of cell-surface receptors that detect components carried by infectious agents. Here we will examine the efficacy of attaching vaccine components to a targeting agent that binds one of these receptors with the aim of enabling dendritic cells to efficiently kick-start immunity against vaccine components.
Febrile Seizures Following Vaccination In Children: How Common Are They And What Is The Long Term Clinical Outcome?

Summary
Seizures following vaccination cause concern for both parent and healthcare providers and in this important study we will measure the risk of febile seizures after vaccines and follow up children who have had a febrile seizure shortly after receiving a vaccine to assess their medical health and developmental outcome. In addition children will be tested to see if they carry one of the known genetic mutations that is asociated with the development of seizures as a potential cause for their seizure ....Seizures following vaccination cause concern for both parent and healthcare providers and in this important study we will measure the risk of febile seizures after vaccines and follow up children who have had a febrile seizure shortly after receiving a vaccine to assess their medical health and developmental outcome.

The Glyco-interactome Of Pathogenic Neisseria: Understanding Disease And Defining Vaccine Targets

Funding Amount
$431,012.00
Summary
In order to infect humans and cause disease, many bacteria rely on interactions with carbohydrate (sugar) structures on human cells. This project aims to characterise the sugar interactions that enable Neisseria meningitidis (causes meningitis, sepsis) and Neisseria gonorrhoeae (causes gonorrhoea, associated with infertility and increased transmission of HIV) to cause disease. This will increase our understanding of host-pathogen interactions and aid development of new vaccines and therapeutics.
Identification Of Novel HCV-specific B Cell Epitopes Which Induce Broad Neutralising Antibodies

Funding Amount
$482,480.00
Summary
This research project will study humans who have been exposed to multiple Hepatitis C virus infections. We will be examining their immune response with the aim to identify subjects with antibodies that are able to neutralise a diverse range of hepatitis C virus variants. These antibodies will be used to identify novel targets for a vaccine directed against Hepatitis C virus.
Sytemic And Mucosal Functional Antibodies In Protection Against HIV

Funding Amount

Summary
Only one human HIV vaccine has shown any level of protective efficacy. However the mechanisms behind how this vaccine was protective are still not fully understood. Additionally, HIV is primarily transmitted through mucosal sites, however very little is know about vaccine immune responses at these sites. Thus this proposal aims to further define the mechanisms of antibody protection against HIV at both systemic and mucosal locations, in order to guide future HIV vaccine design efforts.
Quantifying The Effectiveness Of Pertussis Vaccine In Older Adults

Summary
Pertussis is the most poorly controlled vaccine preventable disease in Australia. Childhood pertussis is a well-known public health problem but adult pertussis is also common and has a significant burden on the health system, especially in adults over 65 years. Pertussis vaccines for adults are currently not funded by our national immunisation program. This project will provide vital data to inform whether pertussis vaccination is cost-effective in older Australian adults.
A vaccine for hepatitis C virus (HCV) is not yet available. Immune responses that are able to protect against infection are possible, making the production of a vaccine a realistic goal. We have produced a unique HCV vaccine and are now poised to test our vaccine in novel humanised animal models. Our research will allow us to determine the immune responses responsible for providing protection against HCV. Our data will be highly significant for future HCV vaccine studies in humans.
Most individuals infected with hepatitis C virus (HCV) develop progressive liver disease. A vaccine is urgently needed, and needs to mimic the immune responses seen in the minority of individuals who clear infection. However, there are large gaps in our understanding of these responses as most acute infections cause no illness and pass unnoticed. This project will fill these gaps by detailed immunological and virological analysis of a large group of subjects with early infection.
