Epidemiological studies of people who are in the early and acute stages of HIV infection are a high-value resource for vaccine design and development, as well as for cure research. In the Protocol C project launched in 2006, IAVI and a wide range of research partners studied volunteers in Kenya, Uganda, Rwanda, Zambia and South Africa to learn more about how HIV is transmitted and HIV disease progression. More than 600 volunteers with incident HIV infection were enrolled in Protocol C. All volunteers were provided with or referred for routine HIV care, including ART provision. Some 190,000 Protocol C samples were collected and more than 26,000 shared with researchers around the world.

Type: Prospective cohort of volunteers with incident HIV infection. 613 volunteers enrolled from nine research centers for long term follow up; 406 suspected transmitting partners for a single visit.

Study Summary:
To evaluate clinical, laboratory, immunologic and viral markers of disease progression in volunteers with recent HIV infection to prepare for activities relevant to the execution of preventive HIV vaccine efficacy trials. If identifiable and willing, HIV-infected partner(s) of enrolled volunteers were assessed for virologic and immunogenetic parameters relevant to transmission.
