The purpose of this review is to assess the extent of missed opportunities for vaccination (MOV) in Africa, determine the associated factors, and provide recommendations that countries could adopt in reducing MOV. Two databases were searched for multinational studies and systematic reviews reporting MOV and involving African countries. A total of 288 records were identified and 12 studies included for synthesis. The prevalence ranged from 47.0% to 62.1%, with a weighted mean of 27.3%. This review highlighted caregiver utilization, health service delivery, and healthcare worker' factors associated with MOV. Understanding the extent of MOV in Africa presents an opportunity for multiple approaches to resolve the differential factors that contribute to MOV, and to bridge the gap in vaccination coverage in the continent.

错失了在非洲接种疫苗的机会。

本次审查的目的是评估非洲错过疫苗接种机会 (MOV) 的程度，确定相关因素，并提供各国可在减少 MOV 方面采取的建议。在两个数据库中搜索了报告 MOV 并涉及非洲国家的多国研究和系统评价。共确定了 288 条记录，并纳入了 12 项研究进行综合。患病率范围为 47.0% 至 62.1%，加权平均值为 27.3%。这篇综述强调了与 MOV 相关的护理人员利用率、医疗服务提供和医护人员的因素。了解非洲 MOV 的范围为多种方法提供了机会，以解决导致 MOV 的不同因素，并弥合非洲大陆疫苗接种覆盖率的差距。
