The primary objectives of this study were to assess the usefulness of C-reactive protein and procalcitonin in the diagnosis of bacterial co-infections in coronavirus disease 2019 (COVID-19) and if their incorporation in antimicrobial stewardship programs is safe and useful, stratified by severity of disease as level of care, intensive care unit (ICU) or non-ICU.
Respiratory syncytial virus (RSV) causes serious illness in children. The Ad26.RSV.preF vaccine candidate was immunogenic with acceptable safety in a phase 1/2a study of RSV-seropositive children. Here, we assessed its safety and immunogenicity in RSV-seronegative children.
Noroviruses are one of the most common causes of gastroenteritis in all age groups, including children. However, little has been reported on the transmission of norovirus within childcare facilities and the subsequent impact at the household level.
In 2024, the government of Western Australia introduced 'nirsevimab', a monoclonal antibody offering protection from respiratory syncytial virus (RSV), for eligible infants. This study explores why parents of infants who were eligible to receive nirsevimab opted to decline or delay the immunisation.
Hepatitis B (HBV) prevalence is very high in pregnant women in the Dolpa district of Nepal, a region characterised by a remote geographic landscape and low vaccination coverage. Using mathematical modelling, we evaluated the impact of third-trimester tenofovir disoproxil fumarate (TDF) prophylaxis on HBV burden and estimated the time required to achieve HBV elimination in Dolpa.
We investigated the genetic and epigenetic regulation of the UBASH3A gene and its association with early-onset sepsis. Using matched whole blood DNA methylation, gene expression, genotypes, and immune cell counts from the EPIC-HIPC newborn cohort, we report that promoter methylation was negatively correlated with ontogenetic changes in UBASH3A gene expression and circulating CD3+ T-cell numbers.
Asymptomatic carriage of Streptococcus pyogenes (Strep A) may contribute to transmission, yet its role remains poorly understood and evidence on optimal detection methods is limited. While self-collected throat swabs are used in infectious disease surveillance, their value for identifying asymptomatic Strep A carriage in adults is uncertain. This pilot prospective cohort study, conducted at a Perth medical research institute between August and October 2024, assessed feasibility and acceptability of self-collection, with sensitivity as a secondary objective.

Syphilis remains a global public health concern, particularly in pregnancy due to the risk of congenital syphilis. The WHO recommends benzathine penicillin G (BPG) as the standard treatment in pregnant women, whilst the optimal dosing strategy has not been established, particularly in relation to the impact of gestational age. This study sought to characterize the pharmacokinetics (PK) of a three-dose regimen of intramuscular BPG, given at weekly intervals, in pregnant women with syphilis.
Licensed recombinant protein respiratory syncytial virus (RSV) vaccines can prevent substantial morbidity in older adults. However, revaccination to prevent waning protection may be suboptimal, prompting the exploration of candidates for heterologous boosting. In this clinical trial of RSV vaccine-naive older adults, we evaluated SCB-1019T, a novel unadjuvanted bivalent RSV prefusion F (preF) protein vaccine stabilized via Trimer-Tag technology, in comparison to the licensed AS01E-adjuvanted RSV vaccine Arexvy.
