Respiratory Syncytial Virus Strain Evolution and Mutations in Western Australia in the Context of Nirsevimab Prophylaxis

Nirsevimab is a long-acting monoclonal antibody used to prevent respiratory syncytial virus (RSV) infection in infants and high-risk children. During the 2024 RSV season in Western Australia, 21 922 doses were administered to infants entering their first season and 1221 doses to at-risk children. In this context, the selection and spread of escape variants are a potential concern. This study aimed to investigate nirsevimab binding site mutations using clinical and wastewater data.

Boosting the influenza vaccine schedule in children with cancer: a prospective open-label study

Current immunization guidelines recommend one dose of influenza vaccine for children aged ≥9 years and two doses for younger or vaccine-naïve children. However, children receiving chemotherapy have an attenuated immune response. We performed a prospective open-label study in children undergoing treatment for cancer at Perth Children's Hospital, Western Australia, to examine the safety and efficacy of a boosted influenza schedule.

Assessment of on-time vaccination coverage in population subgroups: A record linkage cohort study

On-time coverage of the 2-4-6 month schedule is only 50-60% across specific population subgroups representing a significant avoidable public health risk

An audit of the reliability of influenza vaccination and medical information extracted from eHealth records in general practice

To evaluate the reliability of information in GP electronic health records (EHRs) regarding the presence of specific medical conditions and recent influenza vaccination

Using record linkage to examine testing patterns for respiratory viruses among children born in Western Australia

Using linked data, we describe changes in respiratory virus testing among children born in Western Australia in 1996-2012

Using record linkage to validate notification and laboratory data for a more accurate assessment of notifiable infectious diseases

Studies investigating pathogen-specific infectious disease would benefit from using multiple data sources.

Collecting behavioural data across countries during pandemics: Development of the COVID-19 Risk Assessment Tool

Tools that can be used to collect behavioural data during pandemics are needed to inform policy and practice. The objective of this project was to develop the Your COVID-19 Risk tool in response to the global spread of COVID-19, aiming to promote health behaviour change. We developed an online resource based on key behavioural evidence-based risk factors related to contracting and spreading COVID-19. This tool allows for assessing risk and provides instant support to protect individuals from infection.

Perinatal Risk Factors Associated With Gastroenteritis Hospitalizations in Aboriginal and Non-Aboriginal Children in Western Australia (2000-2012)

Given the beneficial effect of infant rotavirus vaccination efforts should be taken to optimize rotavirus vaccine coverage in those at highest risk

Effect of Maternal Influenza Vaccination on Hospitalization for Respiratory Infections in Newborns: A Retrospective Cohort Study

Maternal influenza vaccination was associated with a reduction in the incidence of hospital admission for acute respiratory illness among infants <6 months old
