Building on strong preliminary work, the proposed research is the next logical step in a body of work designed to assess whether refinement of this mobile intervention used in combination with virtual PrEP Peer Navigation will result in improvements in PrEP uptake and a reduction in HIV-related behavior. This is key to advancing HIV prevention among HIV-negative US persons at extremely high-risk for HIV seroconversion.
