Optimising Prevention And Vaccination Policy For Pneumococcal Disease, Influenza And RSV In Indigenous Australians

Summary
Despite recommending pneumococcal vaccine in the Northern Territory since 2000 for Indigenous Australians from 15 years of age, and increasing vaccination coverage, a corresponding reduction in disease has not been observed. This study will provide an evidence base for future vaccination policy by examining whether there is an adequate immune response to pneumococcal vaccination in Indigenous Australians, and whether prior vaccination could reduce the immune response to revaccination.
Community-based Surveillance Of Bacterial Respiratory Pathogens In The NT And WA

Funding Amount

Summary
This surveillance project is a continuation of previous work that describes the strains of respiratory bacterial pathogens in the various community groups - Indigenous and non-Indigenous - across the NT and in WA (urban and remote areas). New vaccines are complex and whilst overall benefits are considerable, there are potential influences on microbiology that may be unwanted. Detailed knowledge of these effects will assist in selection of the best vaccines for use in Australia.

Summary
Otitis media (middle ear disease) is a common childhood infection, and a major concern in remote Aboriginal communities of the Northern Territory. For these children, otitis media commences within the first few weeks of life and progresses to perforation of the ear drum in 60% of children by 12 months of age. Few children in remote Aboriginal communities have normal ear status or normal hearing and many have conductive hearing loss, affecting language development and education.

For these children, otitis media commences within the first few weeks of life and progresses to perforation of the ear drum in 60% of children by 12 months of age. Few children in remote Aboriginal communities have normal ear status or normal hearing and many have conductive hearing loss, affecting language development and education. Otitis media in these children results from infection with the bacteria Streptococcus pneumoniae, Haemophilus influenzae and-or Moraxella catarrhalis. Therefore the types of interventions we are using to combat the high prevalence of ear disease are antibiotic therapy, Streptococcus pneumoniae vaccination, and hygiene interventions. However we fear that the high load of bacteria carried by these children compromises the treatment and prevention strategies. The current proposal will test this hypothesis, and if found to be true, there will be implications for the management of otitis media. For example, dose, frequency and choice of antibiotic treatment, and vaccine schedule changes including an early dose or a booster dose.Read moreRead less
