Development Of A Novel Mannan-based Avian Influenza Vaccine

Funding Amount

Summary
We have a sugar (mannan) that can be used to increase immune responses. We have found that mannan decreases the dose of inactivated virus needed for intranasal immunization. We will investigate if dose sparing is seen when given intramuscularly. This method will be first tried with the human flu virus and if successful will be tried with the bird flu virus. If the preparation can protect mice and ferrets from human or bird flu infection it could develop into a human vaccine against bird flu.
A Multi-protein Vaccine Targeting The Oral Pathogens Associated With Chronic Periodontitis

Summary
Periodontitis is a chronic inflammatory disease associated with specific bacteria leading to the destruction of the toothÍs supporting tissues and ultimately tooth loss and is a major public health problem in all societies. Our research is focused on designing a vaccine that targets the major bacteria associated with periodontitis. We aim to produce a triple antigen vaccine and investigate the applicability of a vaccine administered under the tongue as an alternative to needle injections.
Hendra virus (HeV) cause a disease transmitted from bats to horses which in turn infect humans and other horses. There are no drugs or vaccines for HeV. Since humans are infected by inhalation, a vaccine that can generate antibody in the lung and protect from infection will be ideal. We have found that a natural sugar called mannan used with virus proteins and administered via the nostrils to generate such responses. In this project we will prepare this vaccine and use it in a mouse model of HeV ....Hendra virus (HeV) cause a disease transmitted from bats to horses which in turn infect humans and other horses.

Mucosal Human Immunodeficiency Virus Vaccine Late Pre-clinical Evaluation

Funding Amount
$575,315.00
Summary
Despite many candidate vaccines entering clinical development for protection against HIV, none has yet been successful. This proposal centres on late preclinical development for a novel mucosal vaccine strategy for HIV, which combines a preclinically-proven approach to generating strong T cell immune responses, with an existing approach to generating broadly neutralising antibody responses to HIV. Proof of synergy between these approaches will lead directly to clinical development.
PH-dependent, Antibody-mediated Enhancement Of Genital Chlamydial Infection: Implications For Vaccine Design ?

Funding Amount
$373,228.00
Summary
Antibody found in cervicovaginal secretions is predominantly of the IgG subclass. In the acidic environment of the female reproductive tract IgG antibodies against surface antigens on Chlamydia may actually enhance rather than prevent infection, due to uptake of IgG-coated bacteria by the neonatal Fc receptor (FcRn), which is found on the surface of epithelial cells in the reproductive tract. The proposed studies will determine the effects of chlamydial antibodies on the course of infection.
Understanding The Role Of MAIT Cells In Health And Disease

Funding Amount
$547,593.00
Summary
A specialised set of T lymphocytes called Mucosal Associated Invariant T (MAIT) cells protect us from bacteria and yeast at mucosal sites where the body's immune defences are most easily breached, e.g. gut, oral cavity, airways & reproductive tract. This study investigates the role of MAIT cells in health and in diseases like inflammatory bowel disease, peptic ulceration, periodontitis and tuberculosis. Controlling MAIT cells could help in treating these conditions.
Acupuncture And Mucosal Immunity In The Upper Respiratory Tract

Funding Amount
$383,082.00
Summary
Many Australians seek complementary and alternate medicine for the treatment of allergic diseases such as allergic rhinitis. There is evidence that acupuncture treatment is clinically beneficial for the treatment of allergic rhinitis. This project will produce new information that will provide a scientific basis of how acupuncture influences the immune response and modulates inflammation. Broader application to other inflammatory diseases and therapeutic interventions is possible.
Informing Vaccination Strategies For Pregnant Women Through Linked Population Health Data

Funding Amount
$318,768.00
Summary
Vaccination during pregnancy has health benefits for mothers and their infants; however, it is a relatively new area of research, and the immediate and long-term consequences for children are currently not well understood. As part of this fellowship, I plan to conduct research into the long-term health impacts of vaccination during pregnancy. This fellowship will build my career as a perinatal epidemiologist and establish expertise in Australia related to vaccines given during pregnancy.
Investigating The Altered Landscape Of Enteric Viruses Causing Severe Gastroenteritis In Australian Children Following Rotavirus Vaccine Introduction

Funding Amount
$314,644.00
Summary
The rotavirus vaccines were introduced in Australia in 2007, decreasing rotavirus disease. Rotavirus strains naturally evolve during replication, however, high vaccine coverage in the population creates a new environment with different evolutionary pressures where strains not protected by the vaccines may emerge and become dominant. The diminished circulation of rotavirus may create an environment where other viruses capable of causing childhood gastroenteritis may increase.

Funding Amount

Summary
Vaccination during pregnancy can offer protection against severe respiratory disease for infants in the first six months of life. For this reason, influenza and pertussis vaccines are routinely recommended during each pregnancy. Unfortunately, little is known about the ‘real world’ effect of both vaccines. We plan to conduct the largest and most comprehensive study to date to evaluate all vaccines routinely recommended in pregnancy in Australia.
