Abstract


Nigeria has the second largest HIV epidemic (3.4 million) in the world with 3.2% of her young adults infected. Knowledge and willingness of young adults to participate in early HIV vaccine trial (EHVT) are essential for future interventions. This study aimed to investigate factors influencing willingness to participate (WTP) in EHVT. A cross-sectional study was employed to fetch data from 750 young adults (18-40years) recruited by systematic random sampling between June to December 2016. An informed consent questionnaire addressing socio-demographic factors, contraceptive practices, risky behaviours, knowledge and perception of EHVT study was completed by the participants. Data were analyzed using SPSS version 20 software and p ≤ 0.05 considered significant. Up to 240 (32.0%) of 750 expressed WTP in a vaccine study. There was a significant association between the WTP with; education levels (P=0.001), knowledge about HIV vaccine trial (HVT) studies (P=0.003); a positive insight toward the study (P=0.001); and age group 18-20years (P=0.001). Unwillingness to participate was associated with concerns about fear of reverting back, side effect, fear of spouse, use of parenteral route for its administration. Up to 684 (91.2%) of 750 knew contraceptive was for childbirth control, 241 (32.1%) has never used contraceptive while 172 (23%) used it during last coitus. Refusal to use contraceptive was associated with: religion, its side effect, not married, spouse un-approval, and ignorance. There was a significant association between the WTP with: education level, knowledge about HIV vaccine trial (HVT); a positive insight toward the study; and age group 14-20 years.
