Immunogenicity, reactogenicity, and IgE-mediated immune responses of a mixed whole-cell and acellular pertussis vaccine schedule in Australian infants: A randomised, double-blind, noninferiority trial

In many countries, infant vaccination with acellular pertussis (aP) vaccines has replaced use of more reactogenic whole-cell pertussis (wP) vaccines. Based on immunological and epidemiological evidence, we hypothesised that substituting the first aP dose in the routine vaccination schedule with wP vaccine might protect against IgE-mediated food allergy. We aimed to compare reactogenicity, immunogenicity, and IgE-mediated responses of a mixed wP/aP primary schedule versus the standard aP-only schedule.

Whole-Cell Pertussis Vaccination and Decreased Risk of IgE-Mediated Food Allergy: A Nested Case-Control Study

Australian infants who received whole-cell pertussis vaccines were less likely to be diagnosed with food allergy in childhood

High tidal volume ventilation is not deleterious in infant rats exposed to severe hemorrhage

Both high tidal volume (V(T)) ventilation and hemorrhage induce acute lung injury in adult rodents. It is not known whether injurious ventilation augments lung

Stillbirth and neonatal death rates across time: The influence of pregnancy terminations and birth defects in a Western Australian population-based cohort study

Changes in clinical practice related to pregnancy terminations have played a substantial role in shaping stillbirth and neonatal death rates in WA

Cerebral Palsy Respiratory Health

We know from research that the risk of death from respiratory disease is 14 times higher for adults with cerebral palsy than for other adults. Respiratory disease is the most common cause of premature death in children and young people with cerebral palsy and one of the main causes of hospitalisation.

Transiently increased IgE responses in infants and pre-schoolers receiving only (DTaP) vaccines compared to those initially receiving at least one dose of DTwP vaccine

Confirm the generalised IgE-trophic activity of the DTaP vaccine in pre-schoolers and demonstrate similar (albeit transient) effects in infants

Detection of biofilm in bronchoalveolar lavage from children with non-cystic fibrosis bronchiectasis

The presence of Pseudomonas aeruginosa biofilms in lower airway specimens from cystic fibrosis (CF) patients is well established.

Neonatal skin: barrier, immunity and infection prevention in the NICU

The neonatal skin is central to early survival and immune development. Far from being a passive mechanical barrier, it integrates physical, chemical, and microbial defences that together protect the infant in the immediate postnatal period. In preterm infants, structural immaturity, reduced antimicrobial capacity, and altered microbial colonisation confer heightened vulnerability to infection and inflammation.
