Research Topics

The VRC conducts basic, translational, and clinical research. The primary mission of the VRC Clinical Trials Program (CTP) is to carry out the clinical research component of this triad both through intramural conduct of clinical trials at the NIH Clinical Center and through a broad range of support for external trials conducted by VRC collaborators and partners. These trials include evaluation of candidate vaccines and monoclonal antibodies targeting HIV, influenza, and other emerging infections. A secondary mission of the CTP is to conduct translational immunology research.

Since 2001, the CTP has launched over 70 research protocols involving candidate vaccines and monoclonal antibodies targeting HIV, smallpox, influenza, West Nile virus, Ebola, Marburg, severe acute respiratory syndrome (SARS), malaria, chikungunya, and Zika involving over 10,000 clinical trial volunteer enrollments.

The CTP has also advanced vaccine candidates into both domestic and international Phase Ib, II, and IIb trials. Advanced product development and larger clinical trials require partnership with external clinical trial networks operated or supported by other federal agencies, academia, non-profit organizations, or the private sector. The CTP plays an important role in the planning, conduct, oversight, and analysis of external network clinical trials.
