Background: There is little evidence that women targeted for HIV vaccine efficacy trials understand the procedures and risks associated with participating in them. Methods: We conducted two focus groups with African American and Latina, HIV-negative women recruited in the South Bronx, NYC. Groups were ethnically homogenous. Adult women were eligible if they had used non-injected illicit drugs and reported high-risk sex with men in the prior 3 months. A trained facilitator asked scripted questions about vaccine development and purpose; the immune system; study risks and benefits; and trial concepts (i.e. randomization; blinding). Groups were tape-recorded and observed by two researchers. Final interpretations derive from agreement among the observers and facilitator. Results: Findings differed by ethnicity. African American women were somewhat familiar with, but lacked understanding of, trial concepts. They regarded vaccine developers with distrust and perceived trial concepts as systems to protect against wrong-doing. “Randomization” was perceived as a form of discrimination; “placebo” was seen as a way to detect deviousness; “blinding” was described as a way to protect the researcher from blame if something went wrong. Latina women had less familiarity with, and equally poor understanding of, trial concepts, but expressed no distrust of vaccine developers. Women in both groups confused preventive vaccines with treatment, were dismissive of study risks, but were concerned with becoming HIV-infected via an experimental vaccine. Conclusion: Expressed familiarity with vaccine trial concepts should not be confused with comprehension. Innovative ways to explain complex trial concepts need to be further developed and evaluated.
