Research to Prevention (R2P) is a five-year HIV prevention project funded by USAID. R2P is led by the Johns Hopkins Center for Global Health and managed by CCP. R2Ppartners with faculty throughout the Johns Hopkins Schools of Public Health, Medicine and Nursing, as well as Tulane University, the Medical University of South Carolina, and the University of North Carolina. R2P seeks to answer the question: What are the most effective interventions for preventing the spread of HIV? R2P aims to promote greater use of evidence in the design and implementation of HIV prevention programs in countries most affected by the HIV epidemic. In partnership with organizations in developing countries, R2P will conduct research to identify the most effective interventions for preventing HIV, promote increased use of data to guide programs and policies, and build capacity for applied research among health professionals.
