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, enhancing 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 product development services to translate preclinical findings into clinical trials. Additionally, we are investing in platforms designed for the controlled release of HIV immunogens, simplifying complex 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 critical 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 sustainable research and development in the regions most affected by the HIV epidemic.
