International HIV vaccine trials underway in resource-poor settings provide good examples of how clinical research (CR) can be done in both ethical and culturally-sensitive ways despite a wide variety of obstacles.
Investigators studying "elite suppressors," this unique group of HIV-infected individuals who can ward off illness from HIV for years or even decades, have found clues that might lead to powerful new treatments.
