Treatment as prevention

Emerging pharmaceutical HIV prevention technologies require critique from a wide array of social science perspectives. This article arises from a position paper for a symposium of UK social science and HIV experts where the ideas were further developed. It considers a range of routes of enquiry, including questions about how these technologies interact with individual identity and how we might design evaluations. We conclude by discussing the core principles to consider when undertaking research in this area.
