[Clinical research progress of human respiratory syncytial virus vaccine].

Human respiratory syncytial virus (HRSV) is one of the main pathogen causing severe acute lower respiratory tract infections in infants and the elderly, with high incidence rate and mortality worldwide. Vaccine is one of the important measure to prevent infection, transmission and severe disease of HRSV, but currently there is no officially approved preventive vaccine for prevention of HRSV in the world. This paper reviews and analyzes the current research and development progress of HRSV vaccine, summarizes the design routes of different types of HRSV preventive vaccines, and discusses the difficulties and challenges in vaccine research and development, in order to provide reference for the research and development of HRSV vaccine and the development of clinical trials.人呼吸道合胞病毒（HRSV）是引起婴幼儿和老年人严重急性下呼吸道感染的主要病原体之一，其发病率和病死率在全球范围内均较高。疫苗是预防HRSV感染、传播、重症的重要手段之一，但全球尚未有正式获批的HRSV预防性疫苗。本文对当前HRSV疫苗的研发进展进行梳理和分析，概述不同类型HRSV预防性疫苗的设计路线并讨论在疫苗研发中面临的困难挑战，以期为我国HRSV疫苗的研发和临床试验的开展提供参考。.
