About Us
The Pediatric HIV/AIDS Cohort Study (PHACS) network was established in 2005 to conduct multiple longitudinal cohort studies investigating the long-term effects of HIV and antiretroviral (ARV) medications in children and young adults who were born with HIV or born exposed to HIV.

Pediatric HIV Research Areas
These studies followed newborns, young children, adolescents, and young adults to address two critical pediatric HIV research areas:
The long-term safety of fetal and infant exposure to antiretroviral (ART) medications used to prevent perinatal HIV transmission and for maternal health
The effects of perinatally acquired HIV infection in adolescents and young adults
Clinical Sites
Twenty-five clinical sites across 13 states and Puerto Rico participated in the PHACS studies.

Organizations
The PHACS network was coordinated by Harvard T.H Chan School of Public Health, in partnership with Frontier Science and Westat.
