From 2017 to 2020, ASKAAN collaborated closely with Gavi, UNICEF, and the Senegalese government for the development of the National Strategic Communication Plan for the Expanded Program on Immunization (EPI). This effort involved conducting a knowledge, attitudes, and practices survey to complement the literature review, providing critical insights for the development of the communication plan. Through extensive analysis and collaboration with stakeholders, our team crafted a comprehensive strategic communication plan aimed at promoting vaccination across Senegal.
