Factors Predicting Secondary Respiratory Morbidity Following Early-Life Respiratory Syncytial Virus Infections: Population-Based Cohort StudyThe association between early-life respiratory syncytial virus infections and later respiratory morbidity is well established. However, there is limited evidence on factors that influence this risk. We examined sociodemographic and perinatal factors associated with later childhood respiratory morbidity requiring secondary care following exposure to a laboratory-confirmed RSV episode in the first 2 years.

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

Influenza vaccination in Western Australian children: Exploring the health benefits and cost savings of increased vaccine coverage in childrenTo assess potential benefits and direct healthcare cost savings with expansion of an existing childhood influenza immunisation program, we developed a dynamic transmission model for the state of Western Australia, evaluating increasing coverage in children < 5 years and routinely immunising school-aged children.

Impact of Meningococcal ACWY Vaccination Program during 2017-18 Epidemic, Western Australia, AustraliaThe rising incidence of invasive meningococcal disease (IMD) caused by Neisseria meningitidis serogroup W in Western Australia, Australia, presents challenges for prevention. We assessed the effects of a quadrivalent meningococcal vaccination program using 2012-2020 IMD notification data.

Estimating the excess burden of pertussis disease in Australia within the first year of life, that might have been prevented through timely vaccinationPrevious Australian studies have shown that delayed vaccination with each of the three primary doses of diphtheria-tetanus-pertussis-containing vaccines (DTP) is up to 50 % in certain subpopulations. We estimated the excess burden of pertussis that might have been prevented if (i) all primary doses and (ii) each dose was given on time.

A phase 3, multicenter, randomized, double-blind, active-comparator-controlled study to evaluate the safety, tolerability, and immunogenicity of a 4-dose regimen of V114, a 15-valent pneumococcal conjugate vaccine, in healthy infants (PNEU-PED)Pneumococcal disease (PD) remains a major health concern with considerable morbidity and mortality in children. Currently licensed pneumococcal conjugate vaccines (PCVs) confer protection against PD caused by most vaccine serotypes, but non-vaccine serotypes contribute to residual disease. V114 is a 15-valent PCV containing all 13 serotypes in Prevnar 13™ (PCV13) and additional serotypes 22F and 33F. This pivotal phase 3 study compared safety and immunogenicity of V114 and PCV13.

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

Respiratory Syncytial Virus Strain Evolution and Mutations in Western Australia in the Context of Nirsevimab ProphylaxisNirsevimab is a long-acting monoclonal antibody used to prevent respiratory syncytial virus (RSV) infection in infants and high-risk children. During the 2024 RSV season in Western Australia, 21 922 doses were administered to infants entering their first season and 1221 doses to at-risk children. In this context, the selection and spread of escape variants are a potential concern. This study aimed to investigate nirsevimab binding site mutations using clinical and wastewater data.

Prevalence and subtyping of biofilms present in bronchoalveolar lavage from children with protracted bacterial bronchitis or non-cystic fibrosis bronchiectasis: a cross-sectional studyLower airway biofilms are hypothesised to contribute to poor treatment outcomes among children with chronic lung disease; however, data are scarce.

Preparing for Life: Plasma Proteome Changes and Immune System Development During the First Week of Human LifeNeonates have heightened susceptibility to infections. The biological mechanisms are incompletely understood but thought to be related to age-specific adaptations in immunity due to resource constraints during immune system development and growth. We present here an extended analysis of our proteomics study of peripheral blood-plasma from a study of healthy full-term newborns delivered vaginally, collected at the day of birth and on day of life (DOL) 1, 3, or 7, to cover the first week of life. The plasma proteome was characterized by LC-MS using our established 96-well plate format plasma proteomics platform.
