RESUMO

BACKGROUND: In August 2022, in response to a global mpox outbreak, the World Health Organization recommended the Vaccinia vaccination for at-risk people. METHODS: Case study. RESULTS: We describe a case of a HIV-negative bisexual man who developed a symptomatic mpox infection 13weeks after completing a two-dose course of subcutaneous third-generation modified vaccinia Ankara vaccines. The case likely acquired his mpox infection in the USA; was diagnosed in Aotearoa, New Zealand; and was followed-up in Australia, as he was actively travelling during his infection. CONCLUSIONS: This case highlights the importance of maintaining clinical suspicion for mpox in people who present with consistent symptoms, even if they are fully vaccinated. Also, as he travelled around Aotearoa, New Zealand, and Australia during his infection, this case highlights how public health authorities and clinicians can cooperate across jurisdictional boundaries to support cases and minimise the risk of onward transmission.

RESUMO

Australia has been a world leader in human papillomavirus (HPV) vaccination and was the first country to implement a fully funded national HPV vaccination program, from 2007 for girls and 2013 for boys. In 2018 the program changed from a 4-valent to 9-valent HPV vaccine and a 3-dose to 2-dose standard schedule. We assessed stakeholder perspectives on factors influencing program outcomes and impact as part of a comprehensive program evaluation. In late 2019 and early 2020, we conducted 26 interviews with 42 key stakeholder participants and received 1513 survey responses from stakeholders including general practice staff and school-based nurse immunisers. Findings included that the 2-dose schedule is better accepted by schools and students and has reduced program cost and resource requirements. However, course completion rates have not increased as much as anticipated due to the 6-12 month dosing interval and reduced opportunities for school-based catch-up vaccination. Major reported barriers to increased vaccine coverage were absenteeism and consent form return. Vaccine hesitancy is not currently a major issue but remains a potential threat to the program. While Australia's HPV vaccination program is perceived as highly successful, measures to further enhance the program's impact and mitigate potential threats are important.

RESUMO

Zebrafish craniofacial, skeletal, and tooth development closely resembles that of higher vertebrates. Our goal is to identify viable adult zebrafish mutants that can be used as models for human mineralized craniofacial, dental, and skeletal system disorders. We used a large-scale forward-genetic chemical N-ethyl-nitroso-urea mutagenesis screen to identify 17 early lethal homozygous recessive mutants with defects in craniofacial cartilage elements, and 7 adult homozygous recessive mutants with mineralized tissue phenotypes including craniofacial shape defects, fused sutures, dysmorphic or missing skeletal elements, scoliosis, and neural arch defects. One mutant displayed both an early lethal homozygous phenotype and an adult heterozygous phenotype. These results extend the utility of the zebrafish model beyond the embryo to study human bone and cartilage disorders.
