Implementing PrEP poses new challenges in planning, managing and funding combination prevention. Realizing the promise of PrEP will require governments, funders, civil society and other stakeholders to join forces to systematically address them–licensing antiretroviral medicines for PrEP use, setting priorities for locations and populations for implementation, making services user-friendly and ensuring adherence. These efforts are worthwhile based on their contribution to achieving the global targets of less than 500 000 people annually acquiring HIV in 2020 and the end of AIDS as a public health threat by 2030.
