Participants also experience adverse events associated with voluntary medical male circumcision and the use of microbicides and vaccines in clinical trials. The results obtained from clinical trials investigating the efficacy of microbicides and vaccines in preventing HIV infection are disappointing, but there is hope that one day a breakthrough could be made. Clinical trials on voluntary medical male circumcision and preexposure prophylaxis have shown positive results that warranted approval by the US Food and Drug Administration (FDA) and the World Health Organization (WHO). The major challenge experienced in new HIV prevention clinical trials that are underway and in approved interventions that are being scaled up apparently relates to HIV incidence that threatens the social value and scientific validity of the interventions. Paradoxically, the clinical trials and scale-up interventions have become the new sources of HIV infection although the hypothesized benefit to be realized in the end is conceptualized as outweighing the current risks involved.
