​​​The CAVD Structure

Vaccine Discovery/Development Consortia

The vaccine discovery consortia are exploring a range of innovative approaches for designing vaccine candidates to trigger immune responses believed to be critical for protection against HIV.

The consortia focus on the two biggest scientific obstacles currently facing the field: designing vaccine candidates capable of eliciting broadly neutralizing and other protective antibodies that prevent HIV infection, and improving vaccine candidates so they elicit stronger and more durable protective cellular immune responses.


Central Service Facilities

Four consortia provide centralized services and expertise to the vaccine discovery consortia, enabling investigators to openly share data and materials and compare results using standardized assays. The centralized service facilities include three laboratory networks for evaluating the immune responses elicited by vaccine candidates (T-cell, antibody, and mouse immunology laboratories), a research specimen repository, and a data and statistical management center.

In addition to these services, investigators in the central service facilities engage in research to improve upon current methods of vaccine evaluation, specimen storage, and data analysis.


In total, the CAVD involves more than 600 investigators across 155 institutions in 16 countries: Australia, Brazil, Canada, France, Germany, India, Italy, Portugal, Russia, South Africa, Spain, Switzerland, the Netherlands, the United Kingdom, the United States, and Zambia.

The CAVD is an important contribution of the Bill & Melinda Gates Foundation’s to achieving the goals of the Global HIV Vaccine Enterprise, an alliance of researchers, funders and advocates dedicated to implementing a shared scientific plan to accelerate HIV vaccine development.
