Health impact and cost-effectiveness of COVID-19 booster vaccination strategies in the early post-Omicron era: a dynamic modelling studyFollowing widespread exposure to Omicron variants, SARS-CoV-2 has transitioned to endemic circulation. Populations now have diverse infection and vaccination histories, resulting in heterogeneous immune landscapes. Careful consideration of the value of ongoing vaccination is required through the post-Omicron phase of COVID-19 management to minimise disease burden.

Subcutaneous Infusion of Benzathine Penicillin G Is Acceptable and Preferred Over Intramuscular Injections for Syphilis in Western Australian Sexual Health Clinic AttendeesControlling the syphilis epidemic in Australia is a public health priority. Regular intramuscular (IM) injections of benzathine penicillin G (BPG) are the current standard of care for late latent syphilis in Australia; however, repeated IM BPG injections are painful, and treatment completion rates are low. Early-phase clinical trials have demonstrated the tolerability and safety of high-dose subcutaneous infusions of BPG (SCIP), where the total treatment dose can be delivered at a single visit. Here we describe the experiences and preferences of attendees of Western Australian sexual health clinics in the Perth metropolitan region who have syphilis and were treated with SCIP.

The Unintended Impact of COVID-19 Associated Non-Pharmaceutical Interventions on Paediatric Hospital Admissions: An Interrupted Time Series AnalysisCOVID-19 related non-pharmaceutical interventions (NPIs) disrupted global healthcare utilisation, with notable declines in infection related paediatric hospitalisations. We aimed to identify non-infectious paediatric conditions for which the incidence of hospital admissions increased during the introduction and alleviation of NPIs in 2020.

Impact of vaccine mandates and removals on COVID-19 vaccine uptake in Australia and international comparators: a study protocolVaccination against SARS-CoV-2 was a crucial public health measure during the COVID-19 pandemic. Among the multiple strategies developed to increase vaccine uptake, governments often employed vaccine mandates. However, little evidence exists globally about the impact of these mandates and their subsequent removal on vaccine uptake, including in Australia, France, Italy and the USA.

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

Trimodal skin health programme for childhood impetigo control in remote Western Australia (SToP): a cluster randomised, stepped-wedge trialSkin infections affect physical health and, through stigma, social-emotional health. When untreated, they can cause life-threatening conditions. We aimed to assess the effect of a holistic, co-designed, region-wide skin control programme on the prevalence of impetigo.

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

‘I'm glad my baby has weaned so I don't need to make that decision.’ Understanding breastfeeding-related COVID-19 vaccine narratives on social mediaDuring the coronavirus disease 2019 (COVID-19) pandemic, the infodemic has been highly visible. Vaccine-related advice and evidence-based guidelines for breastfeeding women have lagged, and, at times have been contradictory and confusing. Breastfeeding is an important public health issue with long-lasting health benefits for infants and mothers.

A phase I clinical trial assessing the safety, tolerability, and pharmacokinetics of inhaled ethanol in humans as a potential treatment for respiratory tract infectionsCurrent treatments for respiratory infections are severely limited. Ethanol's unique properties including antimicrobial, immunomodulatory, and surfactant-like activity make it a promising candidate treatment for respiratory infections if it can be delivered safely to the airway by inhalation. Here, we explore the safety, tolerability, and pharmacokinetics of inhaled ethanol in a phase I clinical trial.
