Enhanced Neutralizing Antibody Responses to Rhinovirus C and Age-Dependent Patterns of Infection

Rhinovirus (RV) C can cause asymptomatic infection and respiratory illnesses ranging from the common cold to severe wheezing. The aim was to identify how age and other individual-level factors are associated with susceptibility to RV-C illnesses. Longitudinal data from the COAST (Childhood Origins of Asthma) birth cohort study were analyzed to determine relationships between age and RV-C infections. Neutralizing antibodies specific for RV-A and RV-C (three types each) were determined using a novel PCR-based assay.

One vaccine for life: Lessons from immune ontogeny

There remains a general misconception that the immune status of the fetus and neonate is immature or insufficient. However, emerging research in immune ontogeny prompts reconsideration of this orthodoxy, reframing this period instead as one of unique opportunity. Vaccine responses (qualitative and quantitative) vary between individuals, and across demographic cohorts. Elements of baseline immune status and function predict vaccine response - some of these factors are well described, others remain a subject of ongoing research, especially with the rapidly expanding field of 'omics' research, enabled by development of highly granular immune profiling techniques and increasing computational capacity.

The ORVAC trial: A clinical trial of a third scheduled dose of Rotarix rotavirus vaccine in Australian Indigenous infants to improve protection against gastroenteritis

We hypothesised that scheduling an additional (third) dose of oral human rotavirus vaccine for children aged 6 to <12 months would improve protection

Modelling the seasonal epidemics of respiratory syncytial virus in young children

This paper describes a mathematical model used to predict when an epidemic of respiratory syncytial virus (RSV) will occur so that preventive measures, such...

The Impact of a Multifaceted Tertiary Pediatric Hospital's Antimicrobial Stewardship Service

Antimicrobials are the most commonly prescribed drug class in children. Overuse through inappropriate prescribing is a key driver of antimicrobial resistance and is recognized as one of the top 10 threats to global health by the World Health Organization.

ASCOT ADAPT study of COVID-19 therapeutics in hospitalised patients: an international multicentre adaptive platform trial

SARS-CoV-2 infection is associated with a significant risk of hospitalisation, death, and prolonged impact on quality of life. Evaluation of new treatment options and optimising therapeutic management of people hospitalised with SARS-CoV-2 infection remains essential, but rapid changes in pandemic conditions and potential therapies have limited the utility of traditional approaches to randomised controlled trials.

Spatial distribution of rotavirus immunization coverage in Ethiopia: a geospatial analysis using the Bayesian approach

Rotavirus causes substantial morbidity and mortality every year, particularly among under-five children. Despite Rotavirus immunization preventing severe diarrheal disease in children, the vaccination coverage remains inadequate in many African countries including Ethiopia.

Reopening to the world: how safety, normality and trust in government shape young adults’ COVID-19 vaccine intentions

During the COVID-19 pandemic, and particularly 2020-2021, young adults were often significant transmitters of the virus. Prior to the availability of vaccines for young adults, we sought to understand what would contribute to their uptake of a COVID-19 vaccine and how government policy might intervene. We undertook qualitative interviews between February and April 2021 with 19 participants (aged 18-29) in Perth, Western Australia.

Western Australian health care workers’ views on mandatory COVID-19 vaccination for the workplace

Health care workers (HCWs) are at an increased risk of catching and spreading Coronavirus Disease 2019 (COVID-19) compared with the general community, putting health systems at risk. Several jurisdictions globally have mandated or are looking to mandate COVID-19 vaccines for this cohort, but little is known about the acceptability of this measure, especially in different contexts, and there is little qualitative data to explore nuance, depth, and the reasons behind HCWs’ opinions.
