Unique Identifier : AIDSLINE ICA10/94370297 AB OBJECTIVE: This paper examines the psycho-social aspects of Phase III HIV vaccine trials and their impact on the design and implementation of such trials. Its major thesis is that HIV vaccine trials are very different from most other phase III vaccine trials because exposure to risk of HIV infection is, in general, under individual control. This is especially true for individuals who have extended support networks and preventive education within their community. METHOD: This difference with regard to 'control' between HIV and other vaccine trials has a number of implications for the design and conduct of HIV trials. With reference to the scientific literature on the social aspects of HIV prevention and the recent literature examining social science involvement in HIV vaccine trials, three major issues will be explored: increasing the statistical power of the trial; the problem of 'blinding'; and social 'side effects' of the trial. RESULTS: Analysis indicates that not only can the statistical power of the trial be enhanced by a close monitoring of risk practices but it is essential to a valid interpretation of trial outcome; that blinding may weaken the methodological and scientific soundness of the trial; and that a number of social 'side effects' need to be addressed.
