The study design was a descriptive, mixed-methods study. It consisted of a desk review of reports and strategic documents of EPI, along with stakeholder interviews. Interviews were conducted with decision-makers across the health system: at the national, regional, district levels and in the community. Study participants were selected based on their involvement in the collaborative planning, implementation, monitoring and evaluation of the integrated MenA-MEAS2 campaign (which was in the planning stages when this case study went to print). The study tool included questions about campaign governance, collaboration in campaign planning, micro-planning, and community acceptability.
