PCV10 elicits Protein D IgG responses in Papua New Guinean children but has no impact on NTHi carriage in the first two years of lifeNasopharyngeal colonisation with nontypeable Haemophilus influenzae (NTHi) is associated with development of infections including pneumonia and otitis media. The 10-valent pneumococcal conjugate vaccine (PCV10) uses NTHi Protein D (PD) as a carrier. Papua New Guinean children have exceptionally early and dense NTHi carriage, and high rates of NTHi-associated disease.

Optimising a 6-plex tetanus-diphtheria-pertussis fluorescent bead-based immunoassaySmall volume assays are required for large-scale research studies and in particular paediatric trials, where multiple measures are required from a single sample. Fluorescent bead-based technology (Bioplex/Luminex) allows high through-put and simultaneous quantification of multiple analytes in a single test. This technology uses sets of microspheres, each with a unique spectral address that can be coated with a different antigen of interest.

High concentrations of middle ear antimicrobial peptides and proteins are associated with detection of middle ear pathogens in children with recurrent acute otitis mediaElevated antimicrobial proteins and peptides and cytokines in middle ear effusion are a marker of inflammation and bacterial persistence

Bacillus licheniformis in geogenic dust induces inflammation in respiratory epitheliumWe have previously demonstrated that mice exposed to geogenic dust PM10 experienced an exacerbation of inflammatory responses to influenza A virus.

Rationale and methods of a randomized controlled trial of immunogenicity, safety and impact on carriage of pneumococcal conjugate and polysaccharide vaccines in infants in Papua New GuineaVaccination trials in high endemicity areas are needed to provide evidence and guidance on idea strategies to protect children in these areas against infections

Role of viral and bacterial pathogens in causing pneumonia among Western Australian children: A case-control study protocolWe aim to determine the contribute of bacteria and virus to childhood CAP to inform further development of effective strategies.
The Bacterial Respiratory Infectious Disease Group (BRIDG) has a major focus ear and lung disease involving Streptococcus pneumoniae and Haemophilus influenzae.

The Platform Trial In COVID-19 priming and BOOsting : The immunogenicity, reactogenicity, and safety of licensed COVID-19 vaccinations administered as a second booster in BNT162b2PICOBOO is a randomised, adaptive trial evaluating the immunogenicity, reactogenicity, and safety of COVID-19 booster strategies. Here, we present data for second boosters among individuals aged 18-<50 and 50-<70 years old primed with BNT162b2 until Day (D) 84.

The Platform trial In COVID-19 vaccine priming and BOOsting (PICOBOO) booster vaccination substudy protocolCoronavirus-2019 (COVID-19) vaccination in Australia commenced in February 2021. The first vaccines recommended for use were AZD1222 and BNT162b2, both delivered as a two-dose primary schedule. In the absence of sustained immunity following immunisation, recommendations for booster vaccination have followed. It is likely that periodic boosting will be necessary for at least some Australians, but it is unknown what the optimal booster vaccines and schedules are or for whom vaccination should be recommended.

Clinical predictors of hypoxic pneumonia in children from the Eastern Highlands Province, Papua New Guinea: secondary analysis of two prospective observational studiesPneumonia is the leading cause of death in young children globally and is prevalent in the Papua New Guinea highlands. We investigated clinical predictors of hypoxic pneumonia to inform local treatment guidelines in this resource-limited setting.
