This important work takes as its subject one of medicine’s most pressing arenas of ethical debate. There has been a consistent interest in ethical issues arising in the context of HIV research. Ongoing international and multi-site studies and the continuing search for an HIV vaccine continue to prompt examination of how this research is conducted. Also examined are how participants are engaged in the studies and the obligations of the researchers to individual participants and their communities during the course of and following the conclusion of the research. Each chapter of this book is authored primarily by one of the editors (secondarily by the other) and is accompanied by one to two case studies.
