Zambia's 2024 Measles-Rubella Supplementary Immunization Activity (SIA), conducted from 23 to 28 September across all 116 districts, targeted children aged 9-59 months to address immunization gaps exacerbated by COVID-19 disruptions and responding to ongoing measles outbreaks. This community case study evaluates the effectiveness of microplanning, the feasibility of real-time digital monitoring, and the equity of reaching zero-dose children during Zambia's 2024 Measles-Rubella SIA, using a mixed-method approach to inform scalable immunization strategies in resource-limited settings. Through comprehensive microplanning, strategic community engagement, and real-time digital monitoring, the campaign achieved 97% national coverage and reached 165,000 previously zero-dose children in underserved communities. Implementation utilized Google Sheets and Open Data Kit tools, with quality assurance through over 7,500 supervisory visits. Despite achieving high overall coverage, several challenges emerged: funding delays, logistical constraints in remote areas, and data quality issues. Key lessons include the necessity of timely funding disbursement, strengthened cold chain infrastructure, and rigorous data verification processes. Community involvement through local leadership engagement and radio campaigns proved essential to success, while digital monitoring enabled rapid adaptation to emerging challenges. This case study provides actionable insights for designing equitable immunization campaigns in resource-limited settings, supporting global measles and rubella elimination goals through evidence of effectively tailored, data-driven strategies.
赞比亚于9月23日至28日在所有116个区开展了2024年麻疹-风疹补充免疫活动（SIA），目标人群为9至59个月大的儿童，以解决因新冠疫情干扰而加剧的免疫空白问题，并应对持续的麻疹疫情。本社区案例研究采用混合方法评估了赞比亚2024年麻疹-风疹补充免疫活动中微观规划的有效性、实时数字监测的可行性以及覆盖零剂次儿童的公平性，为资源有限环境下可扩展的免疫策略提供参考。通过全面的微观规划、战略性社区参与和实时数字监测，该活动实现了97%的全国覆盖率，并覆盖了服务不足社区的16.5万名此前未接种过疫苗的儿童。实施过程中使用了谷歌表格和开放数据工具包，并通过7500多次监督访问进行质量保证。尽管总体覆盖率很高，但仍出现了一些挑战：资金延迟、偏远地区的后勤限制以及数据质量问题。关键经验教训包括及时发放资金、加强冷链基础设施以及严格的数据核查流程的必要性。通过当地领导参与和广播宣传活动让社区参与进来被证明是成功的关键，而数字监测能够快速应对新出现的挑战。本案例研究为在资源有限的环境中设计公平的免疫活动提供了可操作的见解，通过有效定制、数据驱动的策略的证据支持全球消除麻疹和风疹的目标。
