Maternal RSVpreF Vaccine Effectiveness Against Respiratory Syncytial Virus in Hospitalized Infants

In February 2025, Australia introduced maternal vaccination with bivalent respiratory syncytial virus prefusion F protein-based vaccine (RSVpreF) in the National Immunization Program for pregnant individuals from 28 weeks' gestation as the primary, year-round strategy to prevent RSV disease in infants 6 months of age or younger.

Infection Triggered Encephalopathies in Australian Children: A National Multicentre Case Series 2013-2024

Infection Triggered Encephalopathy Syndrome (ITES) is a rare but potentially severe complication of infections in children. ITES is a syndrome of acute encephalopathy that occurs in the context of a febrile illness and hypothesised to result from a cytokine mediated infection-triggered cytotoxicity in the central nervous system (CNS) without parenchymal inflammatory cell infiltration. ITES is considered distinct from infectious and immune-mediated encephalitis. We aimed to describe the demographics, associated pathogens, clinical spectrum and outcomes of ITES in Australian children from May 2013 until June 2024.

Mucosal immune cell priming by intranasally delivered Haemophilus haemolyticus is associated with heterologous protection against influenza and nontypeable Haemophilus influenzae

Intranasal vaccines offer a needle-free strategy to enhance immunity to respiratory infections. We investigated the mechanism of action of a novel intranasal vaccine using the human respiratory commensal Haemophilus haemolyticus, previously shown to protect against nontypeable Haemophilus influenzae otitis media and accelerate clearance of influenza A virus.

Using Aboriginal participatory action research within a mixed methods study exploring COVID-19 vaccination uptake in Aboriginal women: a methodological framework for co-design

The COVID-19 pandemic evidenced the critical role of vaccination in reducing the severity of illness and the risk of infection. Despite the policies and efforts of governments to increase vaccination uptake, COVID-19 immunization among Australian Aboriginal pregnant women is lower compared to vaccine uptake of non-Indigenous pregnant women.
