This Implementation Kit (I-Kit), developed by the Health Communication Capacity Collaborative (HC3), helps national and local stakeholders to design country-specific social and behavioural change communication (SBCC) campaigns that address the threat posed by substandard, spurious, falsified and falsely labelled (SSFFC) malaria medicines. These poor-quality medicines endanger lives by failing to treat malaria effectively, undermine health systems, and contribute to drug resistance. The I-Kit provides practical guidance and resources in six sections, including global examples, campaign design elements, media engagement strategies and tools for knowledge sharing. It is intended for health promotion officers, drug regulators, communication specialists and global health partners. Drawing heavily on experiences in Nigeria, the I-Kit promotes evidence-based, context-sensitive SBCC interventions to safeguard communities against SSFFC malaria medicines and enhance treatment outcomes.
