Building an international network of networks for vaccine R&D is the second key component. This network should bring together epidemiology, clinical, preclinical, central laboratory and regulatory capabilities to accelerate development of vaccine candidates, with a focus on enhancing capacities in the Global South. Finally, the GVRC could identify major bottlenecks to international collaboration for vaccine R&D and foster trust. This will require addressing critical issues of clinical trial networks, regulatory harmonization, intellectual property, and availability of inputs, while simultaneously fostering equity, access and engagement with affected communities from the outset.
