Future efficacy testing of interventions to prevent HIV or other infections will require engagement of vulnerable populations. We characterized willingness to participate in a future HIV vaccine trial and barriers to participation among men who have sex with men in a 12-month German cohort study. Among 1015 participants at enrollment, 604 (60%) reported willingness, 60 (6%) were unwilling, 351 (35%) were unsure or refused to answer. Among those unwilling, the primary reason was fear of getting HIV. Among those willing, reasons included protection against HIV and furthering scientific knowledge. In a multivariable logistic regression model, higher odds of willingness to participate were seen among participants at the 12-month visit (aOR: 1.09, 95% CI: 1.04–1.15) and with prior knowledge of HIV vaccine research (aOR: 1.14, 95% CI: 1.06–1.23). Educating potential participants about vaccine research may facilitate recruitment and participation in future trials of HIV vaccine candidates and other prevention interventions.
