世界动物卫生组织（WOAH）《科学与技术评论》最新一期——疫苗在行动——汇集了一批反映这些不断变化之现实的文章。本期内容展现了疫苗接种体系的复杂性，它牵涉科学、政策、经济、行为、治理与国际合作。归根结底，本期表明，成功的疫苗接种计划不仅取决于生物学效力，也取决于那些使疫苗能够产生影响的制度、基础设施与关系。
The latest issue of WOAH’s Scientific and Technical Review – Vaccines in action – brings together a collection of articles that reflect these evolving realities. The content of this issue illustrates the complexity of vaccination systems, which involve science, policy, economics, behaviour, governance and international cooperation. Ultimately, the issue demonstrates that successful vaccination programmes depend not only on biological efficacy but also on the institutions, infrastructures and relationships that enable vaccines to generate impact.
