Summary
Development of a new way to vaccinate against influenza that will make standard vaccines 100 times more potent than conventional syringe injection. The Nanopatch is made from a silicon wafer, bristling with micro-nanoscale spikes. It painlessly deposits vaccine under the skin surface. Experiments in mice show that even a small vaccine payload delivered to the skin generates good immune responses. The Nanopatch vaccination system is expected to be ready for clinical trials within a few years.

Tuberculosis remains a major worldwide health problem, resulting in approximately 3 million deaths per year. Furthermore, people infected with the AIDS virus are at a much greater risk of catching tuberculosis. The only vaccine available for tuberculosis, known as BCG, is not very effective at preventing the disease. Therefore there is an urgent need to develop new vaccines to help combat tuberculosis.

Furthermore, people infected with the AIDS virus are at a much greater risk of catching tuberculosis. The only vaccine available for tuberculosis, known as BCG, is not very effective at preventing the disease. Therefore there is an urgent need to develop new vaccines to help combat tuberculosis. The bacterium that causes tuberculosis is made up of may proteins, some of which are known to induce immune responses in animals and humans. We will produce vaccines that are made from 13 of these important proteins. Using a laboratory animal model that closely mimics human tuberculosis infection, together with sophisticated immunological techniques, we will determine if these vaccines stimulate the right immune response to fight tuberculosis and prevent infection. In addition, we will exploit molecules known to boost immune responses to optimise these vaccines. Further we will study the recently sequenced genome of the tuberculosis bacterium to identify new proteins that may be included in these novel anti-tuberculosis vaccines. This is an internationally competitive project and our team is at the forefront of this research effort. A new, effective tuberculosis vaccine would be a major medical breakthrough and a represent a significant achievement for Australian health and medical research.Read moreRead less

Tuberculosis is a major worldwide health problem. Around one third of the world s population is infected with the bacterium that causes tuberculosis, which results in 2 million deaths per year.

Around one third of the world s population is infected with the bacterium that causes tuberculosis, which results in 2 million deaths per year. Furthermore, people infected with the AIDS virus are at a much greater risk of catching tuberculosis. The only vaccine available for tuberculosis, known as BCG, is not very effective at preventing the disease. Therefore there is an urgent need to develop new vaccines to help combat tuberculosis. This project aims to develop and test novel vaccines to prevent tuberculosis. We will produce forms of the existing BCG vaccine that have been altered to boost the components of the immune system needed to provide optimal protection against tuberculosis. Other potential vaccines that we will test are very similar to the bacterium that causes tuberculosis but have been altered such that they do not cause disease. Using animal models of tuberculosis and sophisticated immunological techniques we wish to determine if these live vaccines can stimulate the right type of immune response needed to fight tuberculosis and prevent infection. This is an internationally competitive project and our team is at the forefront of this research effort. A new, effective tuberculosis vaccine would be a major medical breakthrough and a represent a significant achievement for Australian health and medical research.Read moreRead less
Informing Vaccination Strategies For Pregnant Women Through Linked Population Health Data

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.

Summary
Pneumonia is one of the commonest causes of childhood death worldwide. PCV is a vaccine that prevents pneumonia but it is costly; and causes an increase in disease from strains which are not in the vaccine. Our CRE will address 2 outstanding issues: when to switch from a 3 to 2 dose PCV schedule to make it more affordable; and create new understanding of the non-vaccine strains’ impact on disease in low- and middle-income countries in the Asia-Pacific region.
Investigating The Altered Landscape Of Enteric Viruses Causing Severe Gastroenteritis In Australian Children Following Rotavirus Vaccine Introduction

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.

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.

Summary
Efforts to develop vaccines against malaria still represent a substantial focus of current research activities. Antigens present in the erythrocytic pathogenic stages of the infection account for the majority of targets investigated for potential vaccines. Experimental vaccines targeting the pre-erythrocytic stages [the sporozoite injected by the mosquito, and the hepatic stage parasite) have encompassed a lesser diversity of parasite antigens]. This is the case despite the fact that experimenta ....Efforts to develop vaccines against malaria still represent a substantial focus of current research activities. Antigens present in the erythrocytic pathogenic stages of the infection account for the majority of targets investigated for potential vaccines. Experimental vaccines targeting the pre-erythrocytic stages [the sporozoite injected by the mosquito, and the hepatic stage parasite) have encompassed a lesser diversity of parasite antigens]. This is the case despite the fact that experimentally induced sterile long-lasting immunity in humans has so far only been achieved through exposure to irradiated sporozoites. The acquisition and maintenance of this immunity depends on the use of invasive sporozoites and on the presence of developmentally arrested hepatic stage parasites.Read moreRead less
Diseases caused by the pneumococcus represent the largest cause of vaccine preventable death in the world today, mainly pneumonia and meningitis. In 2011, 16 developing countries will introduce pneumococcal conjugate vaccines, none in east Asia. Lack of research has been a major barrier to their use in the region. We have established an international centre of excellence in the field and we seek support to extend the capacity of this group and to transfer the technology to Vietnam.
Cancer arises through a combination of common DNA mutations which are associated with very poor survival in certain cancers. However, the cause of these mutations was always believed to be external factors (eg. UV light, toxins), Our exciting preliminary results show internal molecules, called circular RNAs, can drive these mutations and this project will investigate how this occurs and study whether targeting these molecules can reduce the incidence of cancers.
