HIV is a rapidly evolving virus, and within an infected individual it continually acquires new mutations and joins together mutations by recombination. We have developed a novel system for studying recombination, and find that different individuals have different recombination rates, which may contribute to why some individuals survive longer. This project aims to identify the mechanisms responsible for differing recombination rates and how we can alter these to improve patient outcome.
The Phylodynamics Of Human Enteroviruses: Informing Vaccine Effectiveness And Outbreak Preparedness

Funding Amount

Summary
Enteroviruses such as EV-A71 are increasing in frequency and in Australia have resulted in the hospitalization of children with severe encephalitis. However, major aspects of their evolution and epidemiology are unknown. We will provide new insights on these important pathogens by revealing which enteroviruses are circulating in the region and whether they arise in specific localities, whether some are commonly associated with severe encephalitis, and whether some pose a greater epidemic threat.
Characterisation Of Rotavirus Vaccine Escape - Potential For Significant Impact On Vaccination Program

Summary
The introduction of rotavirus vaccines have had enormous impact on improving the health of children worldwide. However, the emergence of vaccine escape strains has the potential to significantly reduce the vaccine effectiveness. This study proposes to characterise strains able to escape vaccine protection.
