HIV infection awareness and willingness to participate in future HIV vaccine trials across different risk groups in Abuja, Nigeria.

The purpose of this survey is to generate baseline data on the level of HIV infection awareness and willingness to participate (WTP) in hypothetical vaccine trials, ahead of any trial conduct in Nigeria. In a cross-sectional survey, 500 respondents were interviewed, including sex workers, male motorcycle taxi drivers, students, and the general public. About 153 (30.6%) of the respondents did not believe that correct and consistent use of condom can protect people from getting HIV, while about 66 (13.2%) respondents believed it is possible to get HIV by sharing meal with an infected person. Population groups considered at high risk for HIV were less aware of the disease, however, they were more willing to participate in HIV vaccine trials compared those at low risk of the disease. A total of 55% expressed WTP in a hypothetical vaccine trial after they were informed about it. Age, population group, and ethnicity were significantly associated with WTP.
