The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has provided scientific and financial support throughout the life of the HIV vaccine concept and is providing financial support for this study. .

NIAID has funded research and development of CMV vaccine vectors since 2004. The trial is currently being funded by both parties.

What is VIR-1388?

VIR-1388 is a vaccine designed to stimulate the immune system to produce T cells that can recognize HIV and initiate an immune response to prevent chronic infection. It uses a harmless version of cytomegalovirus (CMV) to deliver HIV vaccine components without causing disease.
