Intranasal phage therapy overcomes antibody neutralization challenges in pulmonary Pseudomonas aeruginosa infections

Phage therapy is a promising approach against multidrug-resistant infections, yet systemic administration can lead to incomplete cures. We investigated the distribution, immune responses, and efficacy of the therapeutic phage KPP10 delivered via intranasal or intraperitoneal routes in murine Pseudomonas aeruginosa lung infection models.

Validity of using a semi-automated screening tool in a systematic review assessing non-specific effects of respiratory vaccines

The abstract screening process of systematic reviews can take thousands of hours by two researchers. We aim to determine the reliability and validity of Research Screener, a semi-automated abstract screening tool within a systematic review on non-specific and broader effects of respiratory vaccines on acute lower respiratory infection hospitalisations and antimicrobial prescribing patterns in young children.

SARS-CoV-2 Infection and Childhood Islet Autoimmunity

This cohort study examines whether there is a temporal association between SARS-CoV-2 infection and the development of islet autoimmunity among Australian children with a first-degree relative with type 1 diabetes.  

FeBRILe3: Risk-Stratification and Diagnosis of Serious Bacterial Infections in Febrile Infants Less Than 3 Months Old

Evidence-based recommendations exist for early discharge (before 48 h) of young infants with fever without source (FWS) at low risk of serious bacterial infections (SBIs). However, concerns regarding the applicability of international data to local contexts may hinder implementation. We aimed to describe the local epidemiology of FWS and evaluate a newly implemented risk-stratification guideline to support practice change.

ATAGI Targeted Review 2021: the national COVID-19 vaccination program

The overarching goal of the Australian coronavirus disease 2019 (COVID-19) vaccination program has been to protect all people in Australia from the harm caused by the novel coronavirus SARS-CoV-2. This review reflects on the role of the Australian Technical Advisory Group on Immunisation (ATAGI) in the national COVID-19 vaccination program, in terms of the initial programmatic and clinical recommendations in the evolving context of evidence relating to the disease and vaccines, epidemiology, and the program rollout.

The Spectrum and Burden of COVID-19-Associated Neurologic Disease in Australian Children 2020-2023

We aimed to describe the clinical spectrum and burden of COVID-19-associated neurologic disease in Australian children.

Serological Responses to Target Streptococcus pyogenes Vaccine Antigens in Patients With Proven Invasive β-Hemolytic Streptococcal Infections

Rising incidence of invasive β-hemolytic streptococcal (iBHS) infections has prompted consideration of vaccination as a preventative strategy for at-risk populations. The benefits of a vaccine targeting Lancefield group A (Streptococcus pyogenes; Strep A) would increase if cross-species immunity against Lancefield groups C/G (Streptococcus dysgalactiae subspecies equisimilis; SDSE) and B (Streptococcus agalactiae; GBS) was demonstrated.

Quantifying the impact of contact tracing interview prioritisation strategies on disease transmission: A modelling study

Contact tracing is an important public health measure used to reduce transmission of infectious diseases. Contact tracers typically conduct telephone interviews with cases to identify contacts and direct them to quarantine, with the aim of preventing onward transmission. However, in situations where caseloads exceed the capacity of the public health system, timely interviews may not be feasible for all cases. Here we present a modelling framework for assessing the impact of different case interview prioritisation strategies on disease transmission.

Immunogenicity, Reactogenicity, and Safety of a Pentavalent Meningococcal ABCWY Vaccine in Adolescents and Young Adults who had Previously Received a Meningococcal ACWY Vaccine

A MenABCWY vaccine containing 4CMenB and MenACWY-CRM vaccine components has been developed to protect against the 5 meningococcal serogroups that cause most invasive disease cases.
