Re-examining Hepatitis B Postexposure Prophylaxis Following Pediatric Community-acquired Needle-stick Injury in an Era of a National Immunization Registry

Long-term hepatitis B immunity has been demonstrated following the completion of the primary vaccination series in childhood. Some guidelines recommend a hepatitis B surface antibody (anti-HBs) directed approach following community-acquired needle-stick injury (CANSI) to inform hepatitis B postexposure prophylaxis (PEP) management.

Multilocus Sequence Typing Reveals Extensive Genetic Diversity of the Emerging Fungal Pathogen Scedosporium aurantiacum

Scedosporium spp. are the second most prevalent filamentous fungi after Aspergillus spp. recovered from cystic fibrosis (CF) patients in various regions of the world. Although invasive infection is uncommon prior to lung transplantation, fungal colonization may be a risk factor for invasive disease with attendant high mortality post-transplantation. Abundant in the environment, Scedosporium aurantiacum has emerged as an important fungal pathogen in a range of clinical settings.

Risk factors and disease severity in Australian infants aged under 6 months hospitalised with influenza 2011–2019

Infants aged <6 months are vulnerable to severe influenza disease and no vaccine is approved for use in this age group. We aimed to describe the epidemiology, risk factors associated with severe outcomes and management of influenza in Australian infants aged <6 months.

The Collaboration for Increasing Influenza Vaccination in Children (CIIVIC): a meeting report

The burden of seasonal influenza disease in Australian children is substantial, especially for those with medical comorbidities including chronic cardiac, respiratory, neurological and immunosuppressive conditions. Influenza is more likely to be severe in children with comorbidities compared to previously healthy children (e.g. more frequent and longer hospitalisation, more frequent intensive care unit admission and requiring respiratory support). Direct protection against influenza by vaccination is critical for children with comorbidities and remains the most effective tool for influenza prevention.

Coronavax: preparing community and government for COVID-19 vaccination: a research protocol for a mixed methods social research project

Ahead of the implementation of a COVID-19 vaccination programme, the interdisciplinary Coronavax research team developed a multicomponent mixed methods project to support successful roll-out of the COVID-19 vaccine in Western Australia. This project seeks to analyse community attitudes about COVID-19 vaccination, vaccine access and information needs. We also study how government incorporates research findings into the vaccination programme.

Parents' COVID-19 vaccine intentions for children under 5 years: Brief reflections from a qualitative study

Australian authorities made COVID-19 vaccines available for children aged under 5 years old with serious comorbidities in August 2022. There is presently no universal programme for young children, but crucial to any rollout's success is whether parents are motivated and able to vaccinate. By examining parents' vaccine intentions, this study aims to inform current and future COVID-19 vaccine roll-outs for children aged under 5 years.

Prevalence of respiratory viruses in community-acquired pneumonia in children: a systematic review and meta-analysis

Respiratory viruses are increasingly detected in children with community-acquired pneumonia but prevalence estimates vary substantially. We aimed to systematically review and pool estimates for 22 viruses commonly associated with community-acquired pneumonia.

The risk of major structural birth defects associated with seasonal influenza vaccination during pregnancy: A population-based cohort study

Seasonal inactivated influenza vaccine (IIV) is routinely recommended during pregnancy to protect both mothers and infants from complications following influenza infection. While previous studies have evaluated the risk of major structural birth defects in infants associated with prenatal administration of monovalent pandemic IIV, fewer studies have evaluated the risk associated with prenatal seasonal IIV.

Whole genome sequencing and molecular epidemiology of paediatric Staphylococcus aureus bacteraemia

The role Staphylococcus aureus antimicrobial resistance genes and toxins play in disease severity, management and outcome in childhood is an emerging field requiring further exploration.
