Optimising a 6-plex tetanus-diphtheria-pertussis fluorescent bead-based immunoassay

Small 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.

Acellular Pertussis Vaccine Given in the Week After Birth Does Not Impair Antibody Responses to Later Childhood Doses

A birth acellular pertussis vaccine may be a valuable alternative for immunity against infant pertussis when a pregnancy pertussis vaccine has not been administered. We assessed whether a birth dose may impair immunoglobulin G (IgG) responses to childhood pertussis boosters.

Immunogenicity and Safety of a 2 + 1 DTPa Priming Schedule in Australian Infants and the Impact of Maternally Derived Antibodies on Pertussis Antibody Responses up to 4 Years of Age

We assessed the impact of maternally derived pertussis antibodies on infant responses to a 2 + 1 vaccine schedule (6 weeks, 12 weeks, and 12 months). Infants with baseline antibodies showed lower IgG responses following the primary vaccination series, but this did not impair booster responses at 4 years of age.

Egg-sensitised infants have elevated CD4+ effector memory T regulatory cells from birth

IgE-mediated sensitisation to egg is common in infants. In some cases, the processes leading to egg sensitisation are established in early life, even before introduction to solid foods. The underlying mechanisms remain poorly understood.

Identifying barriers and facilitators for the effective diagnosis and provision of primary health care for otitis media from the perspective of carers of Aboriginal children

To identify the barriers and facilitators for timely detection and optimal management of otitis media in Aboriginal children in a primary care setting from the perspective of carers of Aboriginal children.

ISOM 2023 research Panel 4 - Diagnostics and microbiology of otitis media

To identify and review key research advances from the literature published between 2019 and 2023 on the diagnosis and microbiology of otitis media (OM) including acute otitis media (AOM), recurrent AOM (rAOM), otitis media with effusion (OME), chronic suppurative otitis media (CSOM) and AOM complications (mastoiditis).

Pneumococcal carriage, serotype distribution, and antimicrobial susceptibility in Papua New Guinean children vaccinated with PCV10 or PCV13 in a head-to-head trial

Children in Papua New Guinea (PNG) are at high risk of pneumococcal infections. We investigated pneumococcal carriage rates, serotype distribution, and antimicrobial susceptibility in PNG children after vaccination with 10-valent or 13-valent pneumococcal conjugate vaccines (PCV10; PCV13).

Histo-blood group antigen profile of Australian Aboriginal children and seropositivity following oral rotavirus vaccination

Histo-blood group antigens (HBGAs) may influence immune responses to rotavirus vaccination.
