Accelerating Innovation: Advancing Opportunities in HIV Vaccine Development

This review outlines the Gates Foundation’s investments in support of global efforts dedicated to the research and development of a safe, highly effective, prophylactic HIV vaccine. Our current Collaboration for AIDS Vaccine Discovery (CAVD) portfolio encompasses a wide range of initiatives, including projects aimed at eliciting broadly neutralizing antibodies, enhanc-ing CD8 T cell responses, and, through central service facilities, developing innovative analytical tools and animal models to assess immune responses. One central service facility also offers prod-uct development services to translate preclinical findings into clinical trials. Additionally, we are investing in platforms designed for the controlled release of HIV immunogens, simplifying com-plex vaccine regimens. Our ultimate objective is to develop a highly efficacious, safe, and durable vaccine that ensures broad access, uptake, and affordability. Furthermore, we emphasize the crit-ical importance of fostering global partnerships, with a focus on supporting research capacity in low- and middle-income countries. By making intentional investments, we aim to stimulate sus-tainable research and development in the regions most affected by the HIV epidemic.
