Abstract

Introduction: Nigeria has one of the highest measles burdens and the lowest vaccination coverage in the world. Geographical disparity in the coverage has also been persistent. Between 2019 and 2021, the Nigerian government introduced the second Measles vaccine (MCV2) into routine immunization (RI). This study evaluated the trends of the MCV2 coverage over time across geographical zones.

Methods: The monthly data on the MCV2 coverage from District Health Information Software (DHIS2) for all the health facilities in Nigeria were aggregated by the geopolitical zone, and the trend of the MCV2 coverage was analyzed over time.

Results: The MCV2 coverage in each zone was approximately 20% when the MCV2 program was launched. The MCV2 coverage was higher in the northern zones (35-42%) than in the southern zones (22-31%) 1 year after the launch. Similarly, at 2.5 years, the MCV2 coverage ranged from 38 to 46% in northern zones, while in southern zones, it ranged from 23 to 37%.

Discussion and conclusion: The introduction of MCV2 as part of the RI schedule potentially narrows down the health inequity in Nigeria.

第二种麻疹疫苗 (MCV2) 在尼日利亚作为常规免疫接种的一部分推出后的发展趋势：简要研究报告。

导言：尼日利亚是世界上麻疹发病率最高、疫苗接种率最低的国家之一。覆盖率的地域差异也一直存在。2019 年至 2021 年期间，尼日利亚政府将麻疹二联疫苗（MCV2）引入常规免疫接种（RI）。本研究评估了不同地理区域的 MCV2 接种率随时间变化的趋势：方法：将地区卫生信息软件（DHIS2）中关于尼日利亚所有卫生机构 MCV2 接种率的月度数据按地理区域进行汇总，并分析 MCV2 接种率随时间变化的趋势：结果：MCV2 项目启动时，各地区的 MCV2 覆盖率约为 20%。启动一年后，北部地区的 MCV2 覆盖率（35-42%）高于南部地区（22-31%）。同样，2.5 年后，MCV2 在北部地区的覆盖率从 38%到 46%不等，而在南部地区则从 23%到 37%不等：将 MCV2 作为 RI 计划的一部分可能会缩小尼日利亚的健康不平等。
