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.

Immune impacts of infant whole-cell and acellular pertussis vaccination on co-administered vaccines

We compared the effect of a heterologous wP/aP/aP primary series (hereafter mixed wP/aP) versus a homologous aP/aP/aP primary schedule (hereafter aP-only) on antibody responses to co-administered vaccine antigens in infants and toddlers.

Mapping the prevalence of soil-transmitted helminth infections in the Western Pacific Region: a spatial modelling study

Soil-Transmitted Helminth (STH) infections are a significant health issue in the Western Pacific Region (WPR). This study aims to produce high-resolution spatial prediction STH prevalence maps for the WPR.

Global participatory wastewater surveillance to understand mpox clade diversity in war and conflict-affected countries

War and conflict severely disrupt public health systems, compromising infectious disease surveillance in many affected regions. Mpox, a re-emerging zoonotic disease, poses a growing global threat, especially in areas where traditional monitoring is inaccessible.The mpox virus has distinct clades with varying transmission and severity.

Nationwide spatial dynamics of taeniasis in Thailand: declining prevalence but shifting focus and One Health risk factors across 2008–2014

The prevalence of taeniasis in Thailand has decreased over the past six decades. However, it remains a public health concern, particularly in focal areas, especially along the border regions where migration between Thailand and neighboring endemic countries is frequent. Spatial distribution analysis provides a useful method for identifying high-risk areas and implementing targeted integrated control measures. This study aimed to examine the spatial patterns of taeniasis in 2008 and 2014, along with their associated One Health risk factors at the sub-district level.

Short term safety profile of respiratory syncytial virus vaccine in adults aged ≥ 60 years in Australia

Australia's active vaccine safety surveillance system AusVaxSafety monitors a number of vaccines, including Arexvy, by reporting on solicited adverse events following immunisation (AEFI) through an online survey sent to vaccinees 3 days post-vaccination as previously described.3 Here we report on survey responses from adults aged ≥60 years receiving Arexvy at primary healthcare practices or pharmacies, who responded to the survey by day 7 post-vaccination.

Feasibility, Safety, and Impact of the Probiotics Lactiplantibacillus plantarum and Bifidobacterium longum subspecies infantis in Papua New Guinean Infants

Childhood mortality in low- or middle-income countries (LMICs) remains a major public health concern, with infections being a leading cause of infant death. Probiotics have shown promise in reducing infection-related morbidity and mortality in preterm infants, but their use in newborns born at or near term in LMICs requires further investigation.

Modelling Micro-Elimination: Third-Trimester Tenofovir Prophylaxis for Perinatal Transmission of Hepatitis B in the Remote Dolpa District of Nepal

Hepatitis B (HBV) prevalence is very high in pregnant women in the Dolpa district of Nepal, a region characterised by a remote geographic landscape and low vaccination coverage. Using mathematical modelling, we evaluated the impact of third-trimester tenofovir disoproxil fumarate (TDF) prophylaxis on HBV burden and estimated the time required to achieve HBV elimination in Dolpa. 

A Novel Unadjuvanted Subunit Respiratory Syncytial Virus Prefusion F Vaccine Induces Potent and Differentiated Functional Immune Responses Compared to AS01-Adjuvanted Arexvy in Older Adults

Licensed recombinant protein respiratory syncytial virus (RSV) vaccines can prevent substantial morbidity in older adults. However, revaccination to prevent waning protection may be suboptimal, prompting the exploration of candidates for heterologous boosting. In this clinical trial of RSV vaccine-naive older adults, we evaluated SCB-1019T, a novel unadjuvanted bivalent RSV prefusion F (preF) protein vaccine stabilized via Trimer-Tag technology, in comparison to the licensed AS01E-adjuvanted RSV vaccine Arexvy. 

Challenges and insights in self-swab surveillance for asymptomatic Streptococcus pyogenes carriage

Asymptomatic carriage of Streptococcus pyogenes (Strep A) may contribute to transmission, yet its role remains poorly understood and evidence on optimal detection methods is limited. While self-collected throat swabs are used in infectious disease surveillance, their value for identifying asymptomatic Strep A carriage in adults is uncertain. This pilot prospective cohort study, conducted at a Perth medical research institute between August and October 2024, assessed feasibility and acceptability of self-collection, with sensitivity as a secondary objective.
