ABSTRACT - CORE AND OPTIONAL COMPONENTS: Investigators at Seattle Children's Hospital propose to establish a site to conduct population-based surveillance for acute gastrointestinal and respiratory infections in children living in King County (population 1.9 million) seeking emergency care or requiring hospitalization for vaccine-preventable or potentially vaccine-preventable conditions. The New Vaccine Surveillance Network (NVSN) site in Seattle provides representation for the Pacific Northwest and the western USA within the national surveillance effort, capturing data from a geographic area with differences in rotavirus and respiratory viral seasonality as well as a state-based immunization program and varied vaccine acceptance rates. The Seattle researchers, led by Drs. Janet Englund and Eileen Klein, are experienced in surveillance for acute gastroenteritis (AGE), rotavirus disease, rotavirus vaccine-effectiveness (VE) studies, acute respiratory diseases, influenza vaccines, respiratory syncytial virus epidemiology, and studies in pregnant women, with a history of successfully conducting collaborative, innovative clinical studies of new and emerging pathogens, vaccines, and vaccine-preventable infections in diverse pediatric population. Seattle Children's Hospital, the only pediatric emergency department in the county, encompasses 85% of pediatric hospital beds, and provides acute care for ~85% of acute respiratory disease requiring hospital admission. We work closely with our state- wide immunization registry, which registers all children born in-state and over 96% of vaccines given to children, to assist in VE studies. With collaboration from the Public Health Department of Seattle-King County (PHSKC), we are able to collect admission data from all hospitals in King County and utilize county-wide surveillance programs tracking all emergency room admissions and hospitalization to calculate adjusted population-based disease and hospitalization rates. Our objectives will be to establish VE for rotavirus and influenza vaccines, calculate population-based disease and hospitalization rates, and detect new and re- emerging pathogens to inform public policy. We will assess the impact of new vaccines as they are developed and new vaccine policies as appropriate, and work collaboratively with other NVSN sites and the CDC to understand the burden of vaccine-preventable diseases by assisting the development of new, innovative projects and protocols. We will also recruit 200 pregnant women and follow these women and their infants for two years to assess enteric and respiratory diseases in mother-infant pairs, and household members, documenting the impact of maternal antibody and disease on childhood infection and severity of disease. We will add to the NVSN effort based on our history of enrollment of appropriate numbers of subjects and controls with documented vaccine histories, high levels of specimens collected which are analyzed at laboratories in Seattle and at CDC, and innovative studies proposed and conducted in high risk populations. The Seattle site will contribute to the understanding and documentation of specific pathogens and new vaccines in children.

摘要-核心和可选成分：西雅图儿童医院的研究人员建议 建立一个地点，对下列地区的急性胃肠道和呼吸道感染进行基于人口的监测： 生活在金郡（人口190万）的儿童寻求紧急护理或需要住院治疗， 疫苗可预防或潜在疫苗可预防的疾病。新的疫苗监测网络 位于西雅图的NVSN网站为太平洋西北部和美国西部提供了 国家监测工作，从轮状病毒和呼吸道感染差异的地理区域获取数据 病毒的季节性以及基于州的免疫计划和不同的疫苗接受率。的 由Janet Englund和Eileen Klein博士领导的西雅图研究人员在监测急性 胃肠炎（AGE）、轮状病毒病、轮状病毒疫苗有效性（VE）研究、急性呼吸道感染 疾病、流感疫苗、呼吸道合胞病毒流行病学和孕妇研究， 成功开展新型和新兴病原体的合作、创新临床研究的历史， 疫苗以及不同儿科人群中疫苗可预防的感染。西雅图儿童医院 该县唯一的儿科急诊科，包括85%的儿科医院床位，并提供 约85%需要住院的急性呼吸道疾病的急诊护理。我们与州政府紧密合作- 广泛的免疫登记，登记所有在该州出生的儿童， 孩子们，以协助VE研究。与西雅图国王县公共卫生部合作 （PHSKC），我们能够收集金郡所有医院的入院数据， 监测项目跟踪所有急诊室入院和住院情况， 人口疾病和住院率。我们的目标是建立轮状病毒的VE， 流感疫苗，计算基于人口疾病和住院率，并检测新的和重新 新兴病原体为公共政策提供信息。我们将在新疫苗研制过程中评估其影响 和新的疫苗政策，并与其他NVSN网站和CDC合作， 通过帮助开发新的、创新的、可预防的疾病， 项目和协议。我们还将招募200名孕妇，并跟踪这些妇女及其婴儿， 用两年时间评估母婴和家庭成员的肠道和呼吸道疾病， 记录母亲抗体和疾病对儿童感染和疾病严重程度的影响。我们 将根据我们招募适当数量受试者和对照的历史，增加NVSN的工作量 有记录的疫苗历史，收集的高水平标本在实验室进行分析， 西雅图和疾病预防控制中心，以及在高危人群中提出和进行的创新研究。西雅图网站 将有助于了解和记录儿童中的特定病原体和新疫苗。
