Delayed diagnosis is associated with complications following invasive meningococcal disease in Australian adolescents and young adults

This study described the presenting features, initial assessment, hospital care, and complications at discharge among Australian adolescents and young adults with Invasive meningococcal disease.

Estimated survival gains from pulselessness-detection technologies in unwitnessed out-of-hospital cardiac arrest in Western Australia: a simulation study

In Australia, two-thirds of emergency medical service attended out-of-hospital cardiac arrests are unwitnessed, and survival is <5% in this group. With the recent incorporation of pulselessness-detection technologies into consumer wearable devices such as smartwatches, the potential exists to convert unwitnessed arrests into device-witnessed cases.

More Convergence on Coercion: Reflecting on Vaccine Mandates in 2026; A Response to Recent Commentaries

As we finalised our analysis of the adoption of mandatory policies for childhood vaccines in four high-income jurisdictions for our publication, “Convergence on Coercion,” every country on earth was grappling with how to drive uptake of COVID-19 vaccines. 

The AuTOMATIC trial: a multicentre digitally-automated, Bayesian, adaptive, parallel, factorial randomised controlled trial of SMS reminders for childhood vaccination

The estimated effectiveness of SMS (short message service) reminders for improving childhood vaccine coverage and timeliness has varied in previous studies. The observed heterogeneity in effectiveness may be explained in part by variation in reminder content or timing of the reminder relative to the vaccine schedule date. We sought to evaluate the effectiveness of a range of SMS reminders of varied content and timing for improving on-time childhood vaccination.

Neonatal and infant mortality after maternal influenza and pertussis vaccination: Probabilistically linked cohort study

Maternal influenza and pertussis vaccination is an important strategy to reduce morbidity and mortality in infants. Previous vaccine safety studies have mostly focused on the association between maternal vaccination and fetal death.

“Our kids are our future”: Barriers and facilitators to vaccine uptake and timeliness among Aboriginal children younger than five years in Boorloo (Perth), Western Australia

Rates of several vaccine preventable diseases, and associated hospitalisation, are higher among Aboriginal and/or Torres Strait Islander children than non-Indigenous children. Western Australia has among the lowest childhood vaccine coverage in Australia, particularly among Aboriginal and/or Torres Strait Islander children. Delayed vaccination is also more common in this population. This project aimed to understand the barriers and facilitators to vaccine uptake and timeliness among Aboriginal and/or Torres Strait Islander children aged under five years in Boorloo (Perth). 

Spatiotemporal patterns of influenza in Western Australia

Understanding the geospatial distribution of influenza infection and the risk factors associated with infection clustering can inform targeted preventive interventions. We conducted a geospatial analysis to investigate the spatial patterns and identify drivers of medically attended influenza infection across all age groups in Western Australia.

Impact and effectiveness of Australia's 2025 hybrid RSV immunisation program: results from the PAEDS-FluCAN Network

Australia introduced a hybrid Respiratory Syncytial Virus (RSV) Maternal and Infant Protection Program (RSV-MIPP) in 2025, using National Immunisation Program-funded RSV vaccine for pregnant people from 28 weeks' gestation and jurisdiction-funded nirsevimab. We estimated real-world effectiveness and assessed the impact of the RSV-MIPP program across a participating surveillance network.

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
