Data from the WHO and UNICEF Estimates of National Immunization Coverage (WUENIC) 2022 revision were analyzed to assess the status of routine immunization in the WHO African Region disrupted by the COVID-19 pandemic. In 2022, coverage for the first and third doses of the diphtheria-tetanus-pertussis-containing vaccine (DTP1 and DTP3, respectively) and the first dose of the measles-containing vaccine (MCV1) in the region was estimated at 80%, 72% and 69%, respectively (all below the 2019 level). Only 13 of the 47 countries (28%) achieved the global target coverage of 90% or above with DTP3 in 2022. From 2019 to 2022, 28.7 million zero-dose children were recorded (19.0% of the target population). Ten countries in the region accounted for 80.3% of all zero-dose children, including the four most populated countries. Reported administrative coverage greater than WUENIC-reported coverage was found in 19 countries, highlighting routine immunization data quality issues. The WHO African Region has not yet recovered from COVID-19 disruptions to routine immunization. It is critical for governments to ensure that processes are in place to prioritize investments for restoring immunization services, catching up on the vaccination of zero-dose and under-vaccinated children and improving data quality.
对世界卫生组织(WHO)和联合国儿童基金会(UNICEF)的《2022年国家免疫规划覆盖率估计》(WUENIC)修订版数据进行了分析,以评估受新冠疫情干扰的WHO非洲区域常规免疫的状况。2022年,该区域白喉-破伤风-百日咳联合疫苗(分别为DTP1和DTP3)首剂和第3剂以及含麻疹疫苗首剂(MCV1)的覆盖率估计分别为80%、72%和69%(均低于2019年水平)。在47个国家中,只有13个国家(28%)在2022年实现了DTP3全球目标覆盖率90%及以上。2019年至2022年期间,记录了2870万零剂次儿童(占目标人群的19.0%)。该区域有10个国家占所有零剂次儿童的80.3%,其中包括人口最多的四个国家。在19个国家发现报告的行政覆盖率高于WUENIC报告的覆盖率,这突出了常规免疫数据质量问题。WHO非洲区域尚未从新冠疫情对常规免疫的干扰中恢复过来。各国政府必须确保制定相关流程,优先投资恢复免疫服务,补上零剂次和未充分接种儿童的疫苗接种,并提高数据质量。
