Vaccination Timeliness In Aboriginal And Non-Aboriginal Infants: Risk Factors For Delayed Vaccination And Impact On Disease Burden—a Record Linkage Study

Funding Amount
$538,183.00
Summary
Vaccination has had a significant impact, but preventable infections continue to occur, perhaps due to delayed uptake of scheduled doses. For the first time, we will link vaccination and other health records to: provide accurate estimates of the impact of vaccination; identify reasons for delayed vaccination; and quantify the expected reduction in disease burden if vaccination timeliness was improved. The study will help determine who would benefit most from efforts to improve timeliness.

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.
Group A Streptococcal Human Challenge Study: Accelerating Vaccine Development

Summary
Infection with group A streptococcus (GAS) is a major cause of morbidity and mortality worldwide, including in the Aboriginal population of Australia. Concerted efforts for vaccine development have been hampered by the absence of a suitable animal model. To address this critical knowledge gap we propose to develop a controlled human infection model of GAS infection. This model will provide a direct pathway for the future appraisal of novel GAS vaccines.
The Role Of Capsid Protein Nucleolar Localisation In Chikungunya Virus: Implications For Vaccine Development

Summary
Chikungunya virus (CHIKV) is a globally widespread mosquito-borne alphavirus capable of causing considerable human morbidity and mortality. With no CHIKV vaccine or antiviral available this proposal aims to develop a live attenuated CHIKV vaccine, rationally designed by investigating the host cell nucleolar trafficking of CHIKV capsid protein. This vaccine has the potential to provide cross-protection against additional arthritogenic alphaviruses endemic to Australia such as Ross River virus.
Using Total Population Data To Describe The Characteristics Of Respiratory Infections In Order To Predict Future Epidemics And Recommend Vaccination Strategies For Western Australian Children

Summary
Respiratory infections are a major reason for children to go to hospital. I am an epidemiologist and I will be using previously collected and linked laboratory and hospital data from Western Australian children to better understand how these infections flow through the population over different seasons. I will then be able to predict future epidemics of respiratory infections and how different vaccine programs might have an impact in reducing how many children are affected by these infections.
Combining Health, Laboratory And Immunisation Data Sources To Identify Opportunities For The Prevention Of Chest Infections In Young Aboriginal And Non-Aboriginal Children

Funding Amount
$428,469.00
Summary
Chest infections are one of the major reasons children are admitted to hospital, particularly in Aboriginal children. This project will determine whether current vaccines have reduced hospital visits and how many children are affected by multiple infections. It will also identify where better vaccination programs are needed. This will be done by bringing together and analysing a range of infection and hospital records to paint a true picture of the impact of chest infections in children.
Impact Of DTP Schedules On The Immunogenicity Of 2 Doses Of 13v-PCV Followed By An Early Booster

Funding Amount
$2,651,687.00
Summary
This project aims to come up with a vaccination schedule to make pneumococcal vaccines more effective and affordable for Fiji and other developing countries. We will evaluate schedules involving a 2 dose primary series in early infancy with a booster at 9 months of age. We will compare the immune responses to 3 different primary series and 2 booster options. The results of this project will be used to provide advice, at global and country levels, regarding introduction of pneumococcal vaccines.

When microorganisms hide inside the cells of the body they are still detected by a set of T lymphocytes which have specific receptors for scrutinising the surface of cells for any changes which might signal an intracellular infection. The immune system is ever vigilant in its search for signs of infection which are generally apparent when molecules called antigens are released by microorganisms and captured by the body's cells. This activates lymphocytes resulting in an immune response capable of eliminating the microorganisms. Scrutiny of the body's cells by lymphocytes occurs continuously even when there is no infection present in the body. Following infection of a cell, microbial antigens reveal the infection by their appearance on the cell surface where they are detected by the immune system's lymphocytes. This occurs through a mechanism called antigen presentation. During antigen presentation the proteins inside the cell, including those of any invading microorganism, are first degraded into shorter molecules called peptides. This event is called antigen processing. A fraction of the peptides created by antigen processing are captured by specialised receptors present on all cells. These receptors are called HLA or histocompatibility molecules. This project examines the molecular events which mediate the capture of peptide antigens by HLA molecules. The main focus is on those peptide antigens which elicit killer T cell responses by the immune system. A knowledge of how these peptides are selected for presentation and how they are captured and carried to the cell surface is fundamental to understanding immune responses to microorganisms, tumours, allergens, transplants and self tissues as in autoimmunity. Therefore the study is of great general relevance.Read moreRead less
