Vaccine To Prevent Influenza Virus And Bacterial Super-infection.

Summary
Influenza viruses have the ability to pre-dispose infected hosts toward secondary bacterial complications. The mortality of viral infections that are complicated by a concurrent, or subsequent, bacterial infection (known as a super-infection), is often greater than that of either the virus or the bacteria alone. We will develop a novel multi-pathogen vaccine candidate against the major upper respiratory tract pathogens - Influenza A and Streptococcus pyogenes to prevent super-infections.
HARNESSING T CELL QUALITY FOR PANDEMIC PREPAREDNESS

Summary
Developing highly effective vaccines is critical to rapidly combat global pandemics. To generate a protective antibody response against novel viruses, a vaccine must elicit a targeted B cell response supported by effective CD4 T cell help. We propose that existing CD4 T cell memory can be harnessed to rapidly and effectively support B cell responses to novel vaccine candidates. This work will contribute to pandemic preparedness strategies and improve the development pathway for new vaccines.
Using Immunological Principles To Inform Malaria Vaccine Design

Summary
Malaria kills ~420,000 people each year worldwide. While a vaccine does exist, efficacy is poor and protection wanes rapidly. We have made breakthroughs in understanding the immune response to malaria that allow us to design a new generation of malaria vaccines. Based on this we aim to generate a vaccine that induces sustained levels of high-quality antibodies targeting multiple targets on the parasite and so can provide sustained long-term protection.
Gamma Delta T Cells: The Fourth Player In CD8 T Cell Immunity

Summary
The immune systems of animals have evolved complex but effective mechanisms to protect against infection with intracellular pathogens. This requires that T cells can distinguish uninfected cells from those harbouring pathogens. This is achieved via recognition of pathogen-derived molecules, which activate the immune system to recognise and fight the pathogen. We have identified a crucial role for a gamma delta T cells in this process, making them essential sentinels of intracellular infection.
Immunomodulatory Vaccines In The Treatment Of Peanut Allergy

Summary
Peanut allergy is the most common cause of food-induced anaphylactic reactions in Australia and is a major burden to our healthcare system. Current clinical practice advice dietary avoidance to prevent fatal anaphylactic responses. We propose the use of an immunomodulatory vaccine to re-write the immune response to peanut antigens, from an allergic to a tolerant phenotype. This study will provide novel insights into rational approaches for manipulating immune memory to food allergens.
