Approximately 40 years have passed since the discovery of the rotavirus and 10 years since the introduction and progressive dissemination of rotavirus vaccines worldwide. Currently, 92 countries have introduced rotavirus vaccines into national or subnational programs with evident impact in disease reduction. Two vaccines have been widely used, and four additional vaccines have been licensed and are being used in defined regions. In this context, one main issue that remains unsolved is the lower vaccine efficacy/effectiveness in low-income countries. An additional partially answered issue relates to rotavirus strain circulation in vaccinated populations. These issues are discussed in this review. The most imperative challenge ahead is to fulfill the WHO's recommendation to introduce rotavirus vaccines in all countries.
自轮状病毒被发现以来,大约已经过去了40年;自轮状病毒疫苗在全球推出并逐步推广以来,也已经过去了10年。目前,92个国家已将轮状病毒疫苗纳入国家或次国家级计划,在减少疾病方面产生了显著影响。两种疫苗已被广泛使用,另外四种疫苗已获许可并在特定地区使用。在此背景下,一个尚未解决的主要问题是低收入国家的疫苗效力/效果较低。另一个部分得到解答的问题与接种疫苗人群中的轮状病毒毒株传播有关。本综述将讨论这些问题。未来最紧迫的挑战是落实世界卫生组织在所有国家引入轮状病毒疫苗的建议。
