Research Areas

HIV Prevention

The IMPAACT HIV Prevention Scientific Committee aims to develop and test biomedical/behavioral interventions to prevent HIV maternal acquisition and mother-to-child transmission (MTCT) and to prevent secondary transmission from perinatally HIV-infected adolescents to sexual partners. Evaluating interventions that prevent MTCT and allow HIV-infected women to safely breastfeed while optimizing their own and their child’s health is a major priority in the developing world. Likewise, secondary transmission from perinatally infected adolescents to sexual partners is a growing area of concern. Priorities include evaluation of:

  • Interventions to prevent mother-to-child HIV transmission in the perinatal period and during breastfeeding while optimizing infant and maternal health outcomes, including HIV vaccines.
  • Safe, effective, and feasible interventions to reduce incident HIV infection in pregnant and breastfeeding women and their partners.
  • Biomedical and behavioral interventions to reduce transmission of HIV from perinatally HIV-infected adolescents to sexual partners.
