Assessing the attitudes, knowledge, and awareness of HIV vaccine research among adults in the United States

OBJECTIVES: To assess HIV vaccine research attitudes, awareness, and knowledge among adults in the general US population, African Americans, Hispanics, and men who have sex with men (MSM). METHODS: Applying results of focus groups and a media content analysis, a survey was designed and conducted to validate key HIV vaccine research themes and messages identified by focus groups and a media content analysis. Between December 2002 and February 2003, 3509 telephone interviews were conducted, including 2008 randomly selected from the general population, and 501 population-specific samples of African Americans and Hispanics, and 500 from MSM. RESULTS: Although the majority of each population believes that an HIV preventive vaccine is the best way to control and end the global AIDS epidemic, only 34.9% of African Americans and 28.8% of the general population are supportive of someone they know volunteering for an HIV vaccine trial. The study also found that 47.1% of African Americans, 26.5% of Hispanics, and 13.4% of MSM believed an HIV vaccine already exists and is being kept secret, and 78.0% of African Americans, 57.5% of Hispanics, and 68.0% of MSM did not know or incorrectly believed that the vaccines being tested could cause HIV infection. A subanalysis of the general population also found that women generally had less knowledge of or a decreased awareness about HIV vaccine research. CONCLUSIONS: Awareness, knowledge, and attitudes toward HIV vaccine research vary by population and these issues must be addressed to ensure an adequate number of volunteers for future domestic HIV preventive vaccine clinical trials. In some populations, barriers such as misinformation and distrust must be targeted to increase support for HIV vaccine research.
