Abstract
Enrollment of US women with sufficient risk of HIV infection into HIV vaccine efficacy trials has proved challenging. A cohort of 799 HIV-negative women, aged 18–45, recruited from three US cities was enrolled to assess recruitment strategies based on geographic risk pockets, social and sexual networks and occurrence of sexual concurrency and to assess HIV seroincidence during follow-up (to be reported later). Among enrolled women, 90 % lived or engaged in risk behaviors within a local risk pocket, 64 % had a male partner who had concurrent partners and 50 % had a male partner who had been recently incarcerated. Nearly half (46 %) were recruited through peer referral. At enrollment, 86 % of women said they were willing to participate in a vaccine efficacy trial. Results indicate that participant and partner risk behaviors combined with a peer referral recruitment strategy may best identify an at-risk cohort willing to participate in future trials.

Inscripción de las mujeres estadounidenses con suficiente riesgo de infección por el VIH en los ensayos de eficacia de vacunas contra el VIH ha resultado difícil. Una cohorte de 799 mujeres VIH negativas, 18–45 años de edad, reclutadas en tres ciudades de Estados Unidos estaba inscrito para evaluar las estrategias de reclutamiento basado en los bolsillos de riesgo geográfico, las redes sociales y sexuales y la aparición de la concurrencia sexual y evaluar seroincidencia VIH durante el seguimiento (que se informara más adelante). Entre las mujeres matriculadas, el 90 % vivían o tenían conductas de riesgo dentro de una bolsa local de riesgo, el 64 % tenían una pareja masculina que tenían parejas concurrentes y el 50 % tenía un compañero que recientemente había sido encarcelado. Casi la mitad (46 %) fueron reclutadas a través de referencias de pares. Al inicio del estudio, el 86 % de las mujeres dijeron que estaban dispuestos a participar en un ensayo de eficacia de la vacuna. Los resultados indican que las conductas de los participantes y socio de riesgo en combinación con una estrategia de reclutamiento remisión semejante mejor puede identificar una cohorte de riesgo dispuestos a participar en los ensayos futuros.
