Individual variation in vaccine immune response can produce bimodal distributions of protectionThe ability for vaccines to protect against infectious diseases varies among individuals, but computational models employed to inform policy typically do not account for this variation. Here we examine this issue: we implement a model of vaccine efficacy developed in the context of SARS-CoV-2 in order to evaluate the general implications of modelling correlates of protection on the individual level.

A modelling approach to estimate the transmissibility of SARS-CoV 2 during periods of high, low, and zero case incidenceAgainst a backdrop ofwidespread global transmission, a number of countries have successfully brought large outbreaks of COVID-19 under control and maintained near-elimination status. A key element of epidemic response is the tracking of disease transmissibility in near real-time. During major out-breaks, the effective reproduction number can be estimated froma time-series of case, hospitalisation or death counts. In low or zero incidence settings, knowing the potential for the virus to spread is a response priority.

The Emerging Omicron Variant, Children and SchoolMany publications have demonstrated the detrimental effects of school closures on children, families and communities in the past two years of the COVID-19 pandemic. Currently, there is a surge of Omicron cases as children prepare to return to school around the world. While many children are asymptomatic or have mild disease, it is nevertheless an important problem.

Intervention effect of targeted workplace closures may be approximated by single-layered networks in an individual-based model of COVID-19 controlIndividual-based models of infectious disease dynamics commonly use network structures to represent human interactions. Network structures can vary in complexity, from single-layered with homogeneous mixing to multi-layered with clustering and layer-specific contact weights. Here we assessed policy-relevant consequences of network choice by simulating different network structures within an established individual-based model of SARS-CoV-2 dynamics.

Preoperative preparation of children with upper respiratory tract infection: a focussed narrative reviewThis review summarises the current evidence for the perioperative preparation in children with upper respiratory tract infections (URTI), including COVID-19 infection. URTI, including COVID-19 infection, are common and frequent in children who present for elective surgery. Children with URTI are at increased risk of perioperative respiratory adverse events.

Epidemiology of Viral Infections in Neonatal Intensive Care Units in Western Australia: A Retrospective Study From 2016 to 2021 Including the COVID-19 PandemicViral infections are associated with significant morbidity and mortality in neonates. The COVID-19 pandemic led to changes in viral epidemiology in Western Australia. The impact on patients in neonatal intensive care is uncertain.

Grief and functional impairment following COVID-19 loss in a treatment-seeking sample: the mediating role of meaningThe COVID-19 pandemic has brought unprecedented levels of grief and psychological distress in community samples. We examined unique pandemic grief risk factors, dysfunctional grief, Post-traumatic Stress Disorder symptoms, general psychiatric distress, disrupted meaning, and functional impairment in a treatment-seeking sample of people bereaved from COVID-19 in the United Kingdom.

Impact of Coronavirus Disease 2019 Public Health Measures on Detections of Influenza and Respiratory Syncytial Virus in Children During the 2020 Australian WinterPublic health measures targeting coronavirus disease 2019 have potential to impact transmission of other respiratory viruses. We found 98.0% and 99.4% reductions in respiratory syncytial virus and influenza detections, respectively, in Western Australian children through winter 2020 despite schools reopening. Border closures have likely been important in limiting external introductions.
