Introduction

To describe vaccine stock-outs at national, district, and health facility levels in the WHO African region.

Areas covered

We conducted a systematic review to identify studies reporting on vaccine stock-outs at national, district, and health facility levels in 47 African countries. We searched both published and unpublished literature, including the WHO/UNICEF Joint Reporting Form (JRF), for eligible studies.

Expert opinion

Countries within the WHO African region continue to face the challenge of vaccine stock-outs at national, district, and health facility levels and this impacts on the delivery of immunization services. The frequency and the proportion of stock-outs vary between countries and between regions within a country. Countries need to put more efforts toward finding lasting solutions to vaccine shortages. We look forward to having more countries reporting vaccine stock-outs especially at the health facility level. Furthermore, countries are currently exploring different approaches for improving vaccine stock management. It is expected that in half a decade from now, more well-designed studies will be available that will inform decision-making

对世卫组织非洲区域国家，地区和卫生机构一级疫苗供应的系统评价。

介绍

描述世卫组织非洲区域国家，地区和卫生机构级别的疫苗库存不足。

覆盖区域

我们进行了系统的审查，以鉴定报告47个非洲国家/地区在国家，地区和卫生机构层面上的疫苗库存不足的研究。我们检索了包括WHO和UNICEF联合报告表（JRF）在内的已发表和未发表的文献，以进行符合条件的研究。

专家意见

世卫组织非洲区域内的国家继续在国家，地区和卫生机构级别面临疫苗库存不足的挑战，这对免疫服务的提供产生了影响。缺货的频率和比例在不同国家之间以及一个国家内不同地区之间有所不同。各国需要付出更多努力，以找到针对疫苗短缺的持久解决方案。我们希望有更多的国家报告疫苗缺货，尤其是在卫生机构一级。此外，各国目前正在探索改善疫苗库存管理的不同方法。预计从现在开始的五年内，将会有更多设计精良的研究为决策提供参考
