This manual has been prepared to guide facilitators and trainers conducting orientation and familiarization sessions with frontline social mobilizers, health and allied workers engaged with polio prevention and other supplementary immunization activities in Somalia. It has been produced to guide an initial workshop and to help clarify the roles and responsibilities of field workers. This guide includes ready to use (and copy) handouts for participants, extra material for trainers and the key facts that trainers, facilitators, and field workers need.
