Summary
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. 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.

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

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. 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
