The Health Communication Capacity Collaborative (HC3) aims to empower organisations to design, implement and evaluate social and behavioural change communication (SBCC) initiatives independently. To this end, it offers a variety of resources, such as the Health COMpass library, SBCC Implementation Kits (I-Kits), online courses, webinars and the Springboard networking platform. These resources support the development of professionals and the implementation of effective health communication strategies across various global health topics.
