This training package is intended to support adolescent girls and young women (AGYW) to play a meaningful role in the rollout of oral PrEP in their communities. Through interactive activities, discussion, and action planning, the training prepares Ambassadors to share information with their peers about oral PrEP as part of combination HIV prevention. Ambassadors also gain skills to support peers who are interested in using PrEP and to build community support for AGYW use of oral PrEP. For any Ambassadors who have not been previously trained on sexual and reproductive health and rights, the training also includes foundational sessions on sexual and reproductive health, human rights, gender, violence and HIV transmission. This training can be implemented partially or in full by community-based organizations, non-governmental organizations, ministries of health, and PrEP implementers. Trained HIV Prevention Ambassadors can also implement the training—or selected portions of it—with their peers.
