IMPAACT 2028

IMPAACT 2028 is an observational study to characterize a cohort of children who may participate in future research related to HIV remission or cure. Children in this study will have previously received early or very early treatment for HIV in other IMPAACT studies or other studies sponsored by the United States National Institutes of Health. Children in this study will complete study visits approximately every six months at which key clinical, immunologic, and virologic outcomes will be assessed for a period of up to seven years.

Site selection was completed in March 2021.
