Summary
BCG (used till recently to prevent tuberculosis) is a potential low cost and readily available vaccine which could reduce the rates of allergy and infection in Australian children. We propose to extend our existing NHMRC-funded trial, which studies whether BCG vaccinatinon given at birth prevents the development food allergy, eczema and infection in the 1st year of life, to see if this effect continues until 5yrs of age. At this age, we can also see if BCG vaccination at birth prevents asthma.

Summary
Currently, premature infants are born without the normal immune defenses of infants born at the correct time because the protective factors that normally pass from the mother to the baby during the last few months of pregnancy have not had time to do so. In addition the tiny premature infants are at risk because they need the expertise of intensive care and are therefore separated from their parents and their parents' organisms which healthy term infants normally pick up from the birth canal and ....Currently, premature infants are born without the normal immune defenses of infants born at the correct time because the protective factors that normally pass from the mother to the baby during the last few months of pregnancy have not had time to do so. In addition the tiny premature infants are at risk because they need the expertise of intensive care and are therefore separated from their parents and their parents' organisms which healthy term infants normally pick up from the birth canal and their parents skin. The infants commonly develop infections from organisms living on their skin surfaces or inside their lungs, stomach or bowels. The babies are living in a hospital environment which they need to survive, but they may pick up particularly unhealthy organisms (pathogens) that produce toxins, which are difficult to treat even with antibiotics. These infections are so severe that one-fifth of the babies die, even in Australia where facilities for premature infants are excellent. Two recent studies overseas have shown that giving premature babies special preparations of certain probiotic organisms decreases the chance of babie developing infections. Probiotics are organisms that have health benefits. Probiotics tighten the spaces between cells to stop bacteria getting into the body, produce substances that kill other bacteria and promote the production of immunoglobulin A by the baby's own cells. Immunoglobulin A is a substance that lines the bowel wall and protects the baby from invasion by bacteria. This study will offer this probiotic product to very premature babies in a trial to see if it produces additional benefits for our babies in Victoria. Around five hundred babies will be given the product and five hundred will be given the placebo ( a harmless inert product which will look just like the real probiotic). Currently 23% of our babies get the serious infections and this study is powerful enough to see if we can reduce the number by one third.Read moreRead less
Reducing Vaccine Preventable Diseases In Children: Using National Active Hospital-based Surveillance To Evaluate And Improve Immunisation Program Performance

Summary
This proposal aims to evaluate and improve upon immunisation policy and programs for the prevention of severe childhood influenza and pertussis. Using our successful Paediatric Active Enhanced Disease Surveillance (PAEDS) network in 6 major children's hospitals across Australia, we will identify gaps in the evidence base needed to better control influenza and pertussis and in particular to ensure programs are delivered in such a way so as to address health inequalities.
Early Environmental Determinants Of Pancreatic Islet Autoimmunity: A Pregnancy To Early Life Cohort Study In Children At Risk Of Type 1 Diabetes

Summary
The doubling in incidence of type 1 diabetes in children over the last 20 years may be explained by our modern environment, including excessive weight gain in pregnancy and early life, inadequate dietary omega- 3 fatty acids or vitamin D, or viral infections. We therefore aim to study children with a family member with type 1 diabetes from the pregnancy and through early childhood to determine the effects of the environment on their risk of developing type 1 diabetes .This will lead to strategie ....The doubling in incidence of type 1 diabetes in children over the last 20 years may be explained by our modern environment, including excessive weight gain in pregnancy and early life, inadequate dietary omega- 3 fatty acids or vitamin D, or viral infections.

Centre Of Research Excellence For The Protection Of Pancreatic Beta Cells

Summary
Type 1 diabetes (T1D) is an autoimmune disorder that results in the destruction of the pancreatic beta cells. The overall aim of the CRE is to elucidate the gene-environment interactions and modifiable environmental exposures that are driving the development of islet autoimmunity and progression to T1D. The CRE will unify and add value to new and established collaborations with multi-disciplinary input from genomics, bioinformatics and systems biology into the investigation of T1D.
Maternal Carriage Of Prevotella During Pregnancy Influences Offspring Innate Immune Responses And Asthma At Age 7

Funding Amount

Summary
This project will investigate the relationship between the bacteria a mother carries in her gut during pregnancy and her baby’s risk of developing allergic disease and asthma. We will investigate underlying immune pathways and conduct experiments in mice to determine whether inoculating mothers with a specific type of bacteria known as Prevotella could be used to prevent food allergies and asthma in the offspring.
Prevention And Improved Management Of Paediatric Food Allergy

Summary
There is an urgent need to prevent food allergy and better manage its consequences. My research will identify: causes of food allergy (primary prevention); factors leading to adverse events in food allergic children (secondary prevention); and the role of food allergy in the ‘atopic march’ i.e. progression to other allergic conditions (tertiary prevention). The results of my research will be used to update policy and practice guidelines to change behaviour and improve clinical care.
