2272. High Interest in Doxycycline for Sexually Transmitted Infection Post-Exposure Prophylaxis (Doxy-PEP) in a Multi-city Survey of Men Having Sex With Men (MSM) Using a Social-Networking App

Background Sexually transmitted infections (STI) in people living with HIV (PLWH) and HIV-uninfected men who have sex with men (MSM) are increasing. Doxycycline post-exposure prophylaxis (doxy-PEP) showed partial efficacy against STI acquisition in a small population of HIV-uninfected MSM using pre-exposure prophylaxis (PrEP). Acceptability in a larger, diverse population of MSM is unknown.
