For PrEP programs to effectively meet the needs of priority populations — including adolescent girls and young women, men who have sex with men, pregnant and breastfeeding women, sex workers, and transgender women — these populations must be meaningfully engaged in community awareness raising, peer support, and advocacy. This participatory workshop gives participants the chance to experience the activities from the HIV Prevention Ambassador Training and learn how the training package can boost the impact of existing PrEP programs.
