The Centers for Disease Control and Prevention (CDC) has announced a funding opportunity titled "PEP Packs: Postexposure Prophylaxis Packs for Immediate Access to HIV and Sexually Transmitted Infection Prevention." This initiative aims to support an implementation research study that evaluates strategies for integrating Postexposure Prophylaxis (PEP) packs into existing Pre-exposure Prophylaxis (PrEP) services, specifically targeting populations disproportionately affected by HIV, such as Black and Hispanic men who have sex with men (MSM) and transgender women (TGW). The program seeks to enhance access to nonoccupational PEP (nPEP) and includes the provision of starter kits containing nPEP medications, STI prophylaxis treatment, and self-testing kits to facilitate immediate prevention following potential exposures. The total funding available for this opportunity is $4.8 million, with a single award anticipated, and applications must be submitted electronically by February 19, 2025.
