Global health reciprocal innovation focuses on bidirectional exchange of interventions between high- and low-income countries to address common public health challenges, moving away from traditional one-way development models. By adapting evidence-based interventions across diverse settings, this approach fosters learning and equitable partnerships between countries. The Mutual Capacity Building Model for Adaptation (MCB-MA) outlines a seven-step process to guide such adaptations, emphasizing collaboration and mutual learning. The steps include exploring scope, developing shared goals, formalizing agreements, sharing expertise, reciprocal training, mutual feedback, and planning future collaborations. This model provides a structured, evidence-based framework to support the equitable and culturally appropriate adaptation of health interventions, encouraging deeper partnerships across global health contexts.
