The seroprevalence of SARS-CoV-2-specific antibodies in Australian children: A crosssectional study

Following reduction of public health and social measures concurrent with SARS-CoV-2 Omicron emergence in late 2021 in Australia, COVID-19 case notification rates rose rapidly. As rates of direct viral testing and reporting dropped, true infection rates were most likely to be underestimated.

Impact of Meningococcal ACWY Vaccination Program during 2017-18 Epidemic, Western Australia, Australia

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.

Genetic Correlates of Biological Aging and the Influence on Prediction of Mortality

Longevity and disease-free survival are influenced by a combination of genetics and lifestyle. Biological age (BioAge), a measure of aging based on composite biomarkers, may outperform chronological age in predicting health and longevity. This study investigated the relationship between genetic risks, lifestyle factors, and delta age (Δage), estimated as the difference between biological and chronological age.

Cost-Effectiveness of Oral Immunotherapy Treatments vs No Treatment for Peanut Allergy in Children

The first peanut oral immunotherapy (OIT) for children was approved by the US Food and Drug Administration (FDA) in 2020. While clinical efficacy is established, evidence on cost-effectiveness-whether the benefits outweigh the costs and adverse effects-remains limited. A variant of OIT, known as probiotic and peanut OIT (PPOIT), has shown similar efficacy in trials.

Association between village coverage of 13-valent pneumococcal conjugate vaccine and vaccine-type pneumococcal carriage among children aged 0–59 months with pneumonia in Papua New Guinea

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

FeBRILe3: Caregiver Satisfaction With Early Discharge of Febrile Infants Under 3 Months Old

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. 

A randomized prospective study of neonatal hepatitis B vaccine immunogenicity in The Gambia and Papua New Guinea

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.

Phase 1 trial of an investigational Tdap booster vaccine with CpG 1018 adjuvant compared with Boostrix in healthy adults and adolescents

This phase 1 trial assessed the safety and immunogenicity of an investigational tetanus/diphtheria/acellular pertussis vaccine combined with CpG 1018 adjuvant 1500 μg (Tdap-1018 1500 μg) or 3000 μg (Tdap-1018 3000 μg) in adults and adolescents.

DNA Methylation signatures underpinning blood neutrophil to lymphocyte ratio during first week of human life

Understanding of newborn immune ontogeny in the first week of life will enable age-appropriate strategies for safeguarding vulnerable newborns against infectious diseases. Here we conducted an observational study exploring the immunological profile of infants longitudinally throughout their first week of life. 

Parental awareness and attitudes towards prevention of respiratory syncytial virus in infants and young children in Australia

To assess parental awareness of respiratory syncytial virus (RSV) and the level of acceptance of future RSV prevention strategies. A cross-sectional online survey was implemented targeting "future" and "current" parents of children aged ≤5 years in Australia.
