The eradication of smallpox is considered one of the greatest achievements of humankind, thanks to vaccination. The widespread availability of childhood vaccines has substantially reduced childhood morbidity and mortality. Devastating infections, such as polio, have almost disappeared due to vaccination. In 2021, it was estimated that vaccination against ten selected pathogens will have averted 69 million deaths between 2000 and 2030. Increases in vaccine coverage and introduction of additional vaccines should reduce lifetime mortality by 72% in the 2019 birth cohort. However, access to vaccines that prevent life-threatening and disabling infectious diseases remains unequal.

Concerns regarding adverse events following immunisation are a barrier to vaccine uptake. Health professionals use vaccine safety surveillance systems (VSSSs) to monitor vaccines and inform the public of safety data. With little known about public attitudes, perceptions, and experiences with VSSS, we examined them in the context of COVID-19 vaccinations in Western Australia.
Type 1 interferons (T1IFNs) are typically expressed in low concentrations under homeostatic conditions, but upon pathogenic insult or perturbation of the pathway, these critical immune signaling molecules can become either protectors from or drivers of pathology. While essential for initiating antiviral defense and modulating inflammation, dysregulation of T1IFN signaling can contribute to immunopathology, making it and its associated pathways prime targets for immune evasion and disruption by pathogens.
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.
Management and outcomes of children hospitalised with acute SARS-CoV-2 infection may differ throughout the pandemic or with admission type (clinical COVID-19, incidental COVID-19 or nosocomial infection).
The relationship between ethnicity and mortality of patients critically ill with COVID-19 in Australia has not been described. Defining those communities at the highest risk of severe COVID-19 may assist with formulating effective public health policy and may improve the equitable delivery of health care in Australia.
Viral infections are associated with significant morbidity and mortality in neonates. The COVID-19 pandemic led to changes in viral epidemiology in Western Australia. The impact on patients in neonatal intensive care is uncertain.
Since the emergence of SARS-CoV-2 in 2019 through to mid-2021, much of the Australian population lived in a COVID-19-free environment. This followed the broadly successful implementation of a strong suppression strategy, including international border closures. With the availability of COVID-19 vaccines in early 2021, the national government sought to transition from a state of minimal incidence and strong suppression activities to one of high vaccine coverage and reduced restrictions but with still-manageable transmission.
Respiratory syncytial virus (RSV) remains a leading cause of mortality and morbidity worldwide. RSV seasonality was disrupted by COVID-19-associated nonpharmaceutical interventions (NPIs). We review RSV seasonality, molecular epidemiology, clinical manifestations, and community awareness to inform future prevention strategies.
