Specific IgA, but Not IgG, in Human Milk from COVID-19-Infected Mothers Neutralizes SARS-CoV-2

This study highlights the importance of human milk in providing anti-severe acute respiratory syndrome coronavirus 2 immunity to newborns. The highest protective activity of human milk against COVID-19 was found in colostrum from infected mothers.

Geospatial joint modeling of vector and parasite serology to microstratify malaria transmission

The World Health Organization identifies a strong surveillance system for malaria and its mosquito vector as an essential pillar of the malaria elimination agenda. Anopheles salivary antibodies are emerging biomarkers of exposure to mosquito bites that potentially overcome sensitivity and logistical constraints of traditional entomological surveys.

Evaluation of Pediatric HIV Postexposure Prophylaxis Guideline Following Child Sexual Assault in Western Australia

HIV postexposure prophylaxis (PEP) following child sexual assault (CSA) is recommended in select cases. High rates of poor adherence to PEP are reported. We evaluated adherence to the recommended management of children following CSA at the tertiary pediatric facility in Western Australia and compared our approach with international guidelines.

Modelling respiratory syncytial virus age-specific risk of hospitalisation in term and preterm infants

Respiratory syncytial virus (RSV) is the most common cause of acute lower respiratory infections in children worldwide. The highest incidence of severe disease is in the first 6 months of life, with infants born preterm at greatest risk for severe RSV infections. 

From speculative to real: Community attitudes towards government COVID-19 vaccine mandates in Western Australia from May 2021 to April 2022

Many governments employed mandates for COVID-19 vaccines, imposing consequences upon unvaccinated people. Attitudes towards these policies have generally been positive, but little is known about how discourses around them changed as the characteristics of the disease and the vaccinations evolved.

Geographical migration and fitness dynamics of Streptococcus pneumoniae

Streptococcus pneumoniae is a leading cause of pneumonia and meningitis worldwide. Many different serotypes co-circulate endemically in any one location. The extent and mechanisms of spread and vaccine-driven changes in fitness and antimicrobial resistance remain largely unquantified.

Statistical considerations for the platform trial in COVID-19 vaccine priming and boosting

The Platform trial In COVID-19 priming and BOOsting (PICOBOO) is a multi-site, adaptive platform trial designed to generate evidence of the immunogenicity, reactogenicity, and cross-protection of different booster vaccination strategies against severe acute respiratory syndrome coronavirus 2 and its variants, specific for the Australian context.

Association between Congenital Anomalies and Late-Onset Bacterial Infections in Neonates Admitted to Neonatal Intensive Care Units in Australia and New Zealand

Compromised neonatal intensive care unit neonates are at risk of acquiring late-onset infections (late-onset sepsis [LOS]). Neonates born with congenital anomalies could have an additional LOS risk. 

Short-Term Safety and Adverse Event Risk Profiles for SARS-CoV-2 Booster Vaccine Doses in Australian Adults: A Survey Study

This study quantifies the short-term risk profiles of seven severe acute respiratory syndrome coronavirus 2 virus (SARS-CoV-2) vaccines-Comirnaty Bivalent BA.1, Comirnaty Bivalent BA.4-5, Comirnaty XBB.1.5, Spikevax Bivalent BA.1, Spikevax Bivalent BA.4-5, Spikevax XBB.1.5 and Nuvaxovid-administered as booster doses in Australia.

Modelling the impact of long-acting monoclonal antibody, maternal vaccine and hybrid programs of RSV immunisation in temperate Western Australia

Two RSV immunisations products: a maternal vaccine, Abrysvo, and a long-acting monoclonal antibody, nirsevimab, both designed to prevent RSV illness in infants, have recently become available. Modelling evidence is required to inform how to optimally use these products in immunisation programs to reduce the burden of RSV in young children.
