The Impact of Obesity on Influenza Vaccine Immunogenicity and Antibody Transfer to the Infant During PregnancyInfluenza vaccination is recommended for pregnant women, offering the dual benefit of protecting pregnant women and their newborn infants against influenza. This study aimed to investigate the impact of body mass index (BMI) on influenza vaccine responses in pregnant women and their newborns.

Effectiveness of nirsevimab in preventing RSV-hospitalisation among young children in Western Australia 2024Respiratory Syncytial Virus (RSV) causes a significant burden of illness for children under 2 years of age. Nirsevimab, a long-acting monoclonal antibody, was registered for RSV prevention in Australia in 2023. In April 2024, Western Australia (WA) launched the country's first state-wide nirsevimab program for all infants and high-risk children entering their second RSV season.

Cohort profile: The WAACHS Linked Data StudyDespite the volume of accumulating knowledge from prospective Aboriginal cohort studies, longitudinal data describing developmental trajectories in health and well-being is limited.

Characterising the SARS-CoV-2 nucleocapsid (N) protein antibody responseSARS-CoV-2 nucleocapsid (N) protein antibodies can be used to identify the serological response to natural infection in those who have previously received a COVID-19 spike-based vaccine. Anti-N antibody responses can also be induced by inactivated whole SARS-CoV-2 virus vaccines, such as CoronaVac. We aimed to characterise antibody responses to the N protein following COVID-19 and following vaccination with CoronaVac.

Potential impact of a maternal vaccine for RSV: A mathematical modelling studyRespiratory syncytial virus is a major cause of respiratory morbidity and one of the main causes of hospitalisation in young children.

Replication and Excretion of the Live Attenuated Tetravalent Dengue Vaccine CYD-TDV in a Flavivirus-Naive Adult Population: Assessment of Vaccine Viremia and Virus SheddingWe assessed replication and excretion of the live attenuated CYD-TDV into biological fluids following vaccination in dengue-naive adults in Australia.

Hospital admissions for skin infections among Western Australian children and adolescents from 1996 to 2012The objective of this study was to describe the occurrence of skin infection associated hospitalizations in children born in Western Australia (WA).

Protocol for Pertussis Immunisation and Food Allergy (PIFA): a case-control study of the association between pertussis vaccination in infancyWe therefore speculate that removal of wP from the vaccine schedule contributed to the observed rise in IgE-mediated food allergy among Australian infants

Combination of clinical symptoms and blood biomarkers can improve discrimination between bacterial or viral community-acquired pneumonia in childrenCombining elevated CRP with the presence or absence of clinical signs/ symptoms differentiates definite bacterial from presumed viral pneumonia better than CRP alone
