The 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.
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).
Respiratory syncytial virus contributes to significant global infant morbidity and mortality. We applied a previously developed statistical prediction model incorporating pre-pandemic RSV testing data and hospital admission data to estimate infant RSV-hospitalizations by birth month and prematurity, focused on infants aged <1 year.
Shortage of ear, nose, and throat specialists in public hospitals can result in delays in the detection and management of otitis media. This study introduced a new hospital-based telehealth service, named the Ear Portal, and investigated its role in improving access to specialist care.
Respiratory syncytial virus (RSV) is a significant cause of respiratory infections in young children. Since 2021, RSV has been a notifiable disease in Australia. However, current surveillance systems focus on hospitalised RSV, with limited surveillance at a community level through primary care clinics. This approach only captures RSV requiring hospitalisation. Less severe illnesses, while not captured, may have significant social and economic impacts including the associated cost of care and absenteeism. The aim of this study is to establish an understanding of the broader burden of RSV in young children in a community setting.
Protection of newborns from infection can be achieved through maternal or vaccine-induced antibodies, but the factors influencing vaccine protection (correlate of protection) and subsequent infant immunity remain insufficiently understood. Further investigation is essential to optimize early-life vaccination strategies.
Dynamic molecular changes in early life follow a robust ontogeny as the infant immune system adapts to the demands of its new environment. Studies of plasma immunomodulatory cytokines and chemokines have previously demonstrated ontogenetic patterns of immune development across the first week of life. However, how plasma cytokine and chemokines concentrations evolve over the first 4 months of life remains unknown.
Serosurveys are considered as a valuable tool in estimating population immunity and infection rates but recruitment of children to provide paediatric estimates can be challenging. A novel approach of sampling children undergoing anaesthesia was utilised for a SARS-CoV-2 serosurvey in Australian children and we explore the reasons for participation, feedback on the approach and importance of research into Coronavirus Diseases 2019 (COVID-19).
Pneumococcal conjugate vaccine (PCV) prevents pneumococcal disease and pneumonia, but indirect effects are poorly understood in low-coverage, high-burden settings like Papua New Guinea (PNG). PNG introduced 13-valent PCV (PCV13) in 2014. We aimed to assess direct and indirect effectiveness of PCV13 against vaccine-type pneumococcal carriage among children with pneumonia or suspected meningitis in PNG
Although evidence supports clinicians to "safely do less" for febrile infants assessed as low risk of serious bacterial infection (SBI), early discharge may increase caregiver concern and reduce satisfaction with care. We captured the self-reported satisfaction and concerns for families enrolled in the study of fever, blood cultures and readiness for discharge in infants less than 3 months old (FeBRILe3), a prospective safety assessment of early discharge of low-risk febrile infants, to aid evaluation of this practice.
