Summary
Between 2009-12 a very large epidemic of whooping cough occurred in Australia. More surprisingly during the course of the epidemic the bacteria that cause whooping cough showed genetic changes that seemed to avoid protection provided by the current vaccine against whooping cough in Australia. This grant seeks to use mathematical models of whooping cough transmission to explain how this occurred and to establish whether alternative vaccination strategies might improve the control of this disease.
Reducing Pertussis Burden By Optimising Molecular Epidemiological Surveillance Of Epidemic Bordetella Pertussis In Australia

Summary
Australia has experienced a prolonged epidemic of pertussis from 2008 to 2012 and is currently experiencing another epidemic. In this project, we aim to elucidate the evolutionary dynamics of the epidemics by genome sequencing and develop a practical high throughput culture independent method for epidemiological typing. The outcomes will be highly significant for surveillance of pertussis infections and designing strategies for control and prevention of pertussis.
Best Practice For The Communication Of Perinatal Booster Recommendations And Optimisation Of The Cocooning Strategy.

Summary
Whooping cough continues to be common in Australia. Young babies, who have little or no protection to the infection, are often hospitalised and can die. Adults generally experience milder symptoms which often go undiagnosed and can pass on whooping cough to babies, particularly within the home. To reduce this risk by 70%, parents can receive a booster vaccination for whooping cough. Offering this on the postnatal ward will help remove barriers and provide a cocoon of protection for the newborn.
Evolution Of Pertussis Epidemics And Effect Of Genotypes On Infection Outcomes And Immunisation

Summary
Pertussis, or whooping cough, is caused by Bordetella pertussis. Despite high vaccine coverage, the incidence of pertussis has increased substantially in recent years in Australia. One of the contributing factors is changes in the pertussis strains. This project will determine the genetic composition and virulence characteristics of epidemic strains in Australia and investigate the effect of these strains on disease severity and vulnerability of vaccinated individuals to infection.
Case-cohort Study Of The Association Between Pertussis Vaccination In Infancy And The Risk Of IgE-mediated Food Allergy.

Summary
Allergic diseases are one of the most important causes of chronic morbidity among children in Australia. This is a retrospective case-controlled trial, utilising data from the Australian immunisation register and cases of confirmed food allergy, to examine the role of vaccination in protection against food allergy. If a relationship between the type of vaccination and protection against allergy is found, this would have implications for allergy prevention and immunisation policy.
Assessing Vaccine Effectiveness Of Publicly Funded Vaccination Programs In Queensland

Funding Amount
$99,883.00
Summary
I will measure how well three vaccines on the national immunisation schedule prevent disease in Queensland. Pertussis (whooping cough), rotavirus, and varicella (chicken-pox) vaccines will be assessed using routinely collected health data, such as disease notifications and hospitalisations, and vaccination data. The findings of this research will contribute to evaluating the effectiveness of these publicly funded vaccination programs and will provide an evidence base for future decision-making.
Quantifying The Effectiveness Of Pertussis Vaccine In Older Adults

Funding Amount

Summary
Pertussis is the most poorly controlled vaccine preventable disease in Australia. Childhood pertussis is a well-known public health problem but adult pertussis is also common and has a significant burden on the health system, especially in adults over 65 years. Pertussis vaccines for adults are currently not funded by our national immunisation program. This project will provide vital data to inform whether pertussis vaccination is cost-effective in older Australian adults.
