Immune impacts of infant whole-cell and acellular pertussis vaccination on co-administered vaccinesWe compared the effect of a heterologous wP/aP/aP primary series (hereafter mixed wP/aP) versus a homologous aP/aP/aP primary schedule (hereafter aP-only) on antibody responses to co-administered vaccine antigens in infants and toddlers.

Novel coenzyme Q6 genetic variant increases susceptibility to pneumococcal diseaseAcute lower respiratory tract infection (ALRI) remains a major worldwide cause of childhood mortality, compelling innovation in prevention and treatment. Children in Papua New Guinea (PNG) experience profound morbidity from ALRI caused by Streptococcus pneumoniae. As a result of evolutionary divergence, the human PNG population exhibits profound genetic variation and diversity. To address unmet health needs of children in PNG, we tested whether genetic variants increased ALRI morbidity.

Clinical outcomes and severity of laboratory-confirmed RSV compared with influenza, parainfluenza and human metapneumovirus in Australian children attending secondary careAcute lower respiratory infections (ALRIs) are a major contributor to the global infectious disease burden and a common cause of hospitalisation for children under 2 years. We compared clinical severity in children hospitalised with respiratory syncytial virus (RSV), parainfluenza virus (PIV), human metapneumovirus (hMPV) and influenza virus (IFV).

An infant mouse model of influenza-driven nontypeable Haemophilus influenzae colonization and acute otitis media suitable for preclinical testing of novel therapiesNontypeable Haemophilus influenzae (NTHi) is a major otitis media (OM) pathogen, with colonization a prerequisite for disease development. Most acute OM is in children <5 years old, with recurrent and chronic OM impacting hearing and learning. Therapies to prevent NTHi colonization and/or disease are needed, especially for young children. Respiratory viruses are implicated in driving the development of bacterial OM in children.

“We've wanted to vaccinate against it and now we can”: views of respiratory syncytial virus disease and immunisation held by caregivers of Aboriginal children in Perth, Western AustraliaRespiratory syncytial virus (RSV) is a major cause of respiratory infection with a higher burden in Aboriginal and Torres Strait Islander infants and children. We conducted a pilot qualitative study identifying disease knowledge and willingness to immunise following the changing immunisation landscape for infant RSV in 2024.

Breadth of immune response, immunogenicity, reactogenicity, and safety for a pentavalent meningococcal ABCWY vaccine in healthy adolescents and young adultsA multicomponent meningococcal serogroups ABCWY vaccine (MenABCWY) could provide broad protection against disease-causing meningococcal strains and simplify the immunisation schedule.

Clinical trial to examine whether “mixing” COVID-19 vaccine boosters is more effectiveTop infectious disease experts in Australia will lead a clinical trial to determine whether combining different Covid-19 vaccines in the nation’s booster immunisation will increase effectiveness.

The genomic evolutionary dynamics and global circulation patterns of respiratory syncytial virusRespiratory syncytial virus (RSV) is a leading cause of acute lower respiratory tract infection in young children and the second leading cause of infant death worldwide. While global circulation has been extensively studied for respiratory viruses such as seasonal influenza, and more recently also in great detail for SARS-CoV-2, a lack of global multi-annual sampling of complete RSV genomes limits our understanding of RSV molecular epidemiology.

FeBRILe3: Safety Evaluation of Febrile Infant Guidelines Through Prospective Bayesian MonitoringDespite evidence supporting earlier discharge of well-appearing febrile infants at low risk of serious bacterial infection (SBI), admissions for ≥48 hours remain common. Prospective safety monitoring may support broader guideline implementation.
