50% of the women who died due to swine flu were pregnant. This project will examine if factors produced by the placenta make the pregnant woman more susceptible to influenza.
Pandemic Influenza Containment Strategies In Aboriginal Communities: What Is Acceptable And Feasible?

Funding Amount
$1,056,688.00
Summary
Influenza is a serious disease with a much greater impact in Indigenous communities. This project will work with Aboriginal communities in NSW, north Qld and WA on modifying the national pandemic influenza plan to develop control strategies that are acceptable to the culture and circumstances of those communities. A template and acceptable process will then be offered to other Indigenous communities, finally leading to negotiation to modify implementation of pandemic influenza plans.
How The Placental Protein Syncytin Impairs Maternal Immune Responses To Influenza

Summary
Pregnant women are known to be highly susceptible to certain viral infections, especially influenza, which results in severe illness and even death. The reason for this transitory susceptibility are unknown. We have found that a protein, Syncytin, has the ability to impair maternal immune responses to influenza We now will determine how it does this and discover potential interventions to reverse these effects.
Harnessing Tyrosine Metabolism To Combat Respiratory Diseases

Summary
Cross-talk between our immune system and the microbiome is central to health and disease. In particular, the gut microbiome has wide-ranging effects throughout the body, in part through the production of metabolites with immunomodulatory activity. We have discovered a novel subset of microbial metabolites which can protect mice against allergic airway inflammation, a model of asthma. We now aim to discovery how these metabolites work with a view towards developing them as therapeutics.
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.
Assessment Of Interventions For Controlling Pandemic Influenza And Determining Data Needs To Inform These Assessments

Summary
The aim of this study is to help us prepare for a pandemic of influenza by comparing how effective the various available control strategies are at reducing transmission of the disease. The available control interventions include: reducing the number of close contacts we make with others, isolating cases after they are diagnosed, closing schools, quarantining households, quarantining individuals who are known to have been exposed to a case, and using antiviral drugs treat and protect people at ri ....The aim of this study is to help us prepare for a pandemic of influenza by comparing how effective the various available control strategies are at reducing transmission of the disease. The available control interventions include: reducing the number of close contacts we make with others, isolating cases after they are diagnosed, closing schools, quarantining households, quarantining individuals who are known to have been exposed to a case, and using antiviral drugs treat and protect people at risk of being infected. We will compare these control measures by taking due account of the ability and resources available for these interventions, and with regard to the need to maintain essential services. The comparisons will be made using mathematical models that describe the transmission of the infection. All available data and advice from experts will be used to ensure that realistic models are used for the comparisons. We will also use the models to determine the best use of the limited antiviral drugs available, until a vaccine becomes available. We will consider how the control strategy should be changed if a strain develops that is resistant to the antiviral drugs. In addition, we will determine what data need to be collected during the early stages of a pandemic to help us to determine the best use of the antiviral drugs, the best use of a new vaccine and to check on the development of resistance to the antiviral drugs.Read moreRead less
Generation Of Protective Immunity Against Severe Influenza Disease In Indigenous Australians

Funding Amount
$1,630,970.00
Summary
Hospitalisation and death rates from influenza are high in the Indigenous population, especially when a new virus emerges. There is an urgent need for a vaccine that protects against all influenza strains. T cells recognising conserved viral regions elicit such protection. As T cells are restricted by proteins called HLAs, which vary across ethnicities, we will define T cell regions for HLAs prominent in Indigenous Australians and define how to generate protective immunity against influenza.
THE IMMUNOLOGICAL LEGACY OF OBESITY ON VIRAL PATHOGENESIS

Funding Amount
$652,275.00
Summary
Obesity is a key risk factor for severe viral infections. Our preliminary data suggest that in mice this susceptibility is not reduced by weight loss. In this grant we will investigate a) the mechanisms driving the legacy effect of obesity on antiviral immunity b) whether or not we can reverse this legacy effect by treatment with the drug MCC950 and c) the antiviral response of overweight children and adults who have and haven't recently lost weight.

Summary
In preparing for a future pandemic of influenza, it is important to learn as much as possible from what happened in the past, particularly from the devastating pandemic of 1918-19. This project will collate detailed information about the spread of influenza in past outbreaks and create a publicly accessible data-base.

This project will collate detailed information about the spread of influenza in past outbreaks and create a publicly accessible data-base. Mathematical methods will be used to analyse historic and contemporary data, so as to provide better understanding of the spread of influenza, and of the likely effects of social and medical measures for its control. An important theme of the project is to consolidate our knowledge about how past exposure to non-pandemic influenza could provide short-lived protection against any new pandemic, and to explore the implications of this for prevention today. Another theme is to explore the severity of influenza during pandemics, and to identify social and medical factors that might reduce the dose of virus transmitted, or otherwise reduce the severity of infection. The insights from the modeling will also help to identify gaps in knowledge and understanding about the basic biology of influenza, stimulate new research to fill those gaps, and thus offer the prospect of more effective vaccines and treatments for the future control of influenza.Read moreRead less
