项目摘要

The purpose of this contract is to understand the pathogenesis of important respiratory and enteric viral pathogens of humans and to develop means to prevent illness caused by these viruses. Johns Hopkins University will provide volunteers and a facility in which to study the biology of medically important viruses in humans, to examine the hosts' immune response to these viruses and to test new candidate live virus vaccines for safety, genetic stability, immunogenicity, transmissibility and protective efficacy Studies will also include administration of wild type viruses to volunteers in order to assess virulence. Subsequently, these wild viruses will be used to challenge vaccinated volunteers in order to assess the extent of immunity induced by candidate vaccines. Studies with vaccines will include an evaluation of their safety, immunogenicity, transmissibility, and protective safety. These studies will include both adult and pediatric subjects since the viruses studied cause disease in both these populations; e.g., influenza A viruses causes severe respiratory disease in the elderly and, conversely, respiratory syncytial virus causes severe respiratory disease in infants. In summary, this contract will provide both the facility and volunteers, (adult and pediatric populations) to study the biology and immunology of a variety of viral pathogens and will serve as a testing center for the development of new vaccines effective against these agents.

该合同的目的是了解人类的重要呼吸和肠病毒病原体并发展预防这些病毒引起的疾病的手段。约翰·霍普金斯大学将为志愿者提供研究人类医学上重要病毒的生物学，检查宿主的生物学对这些病毒的免疫反应并测试新的候选活病毒安全性，遗传稳定性，免疫原性，传播性的疫苗保护功效研究还将包括野生为志愿者键入病毒以评估毒力。随后，这些野生病毒将用于挑战接种式志愿者为了评估候选疫苗诱导的免疫力程度。疫苗的研究将包括评估其安全性，免疫原性，传播性和保护性安全性。这些研究将包括成人和儿科受试者病毒研究引起这两个人群的疾病。例如，流感病毒在老年人中引起严重的呼吸道疾病，相反，呼吸道合胞病毒会引起严重的呼吸系统疾病在婴儿中。总而言之，该合同将同时提供设施和志愿者（成人和儿科人群）研究生物学和多种病毒病原体的免疫学，将作为测试针对这些药物有效的新疫苗开发中心。
