Abstract
CEPI (the Coalition for Epidemic Preparedness Innovation)'s CMC rapid response framework is developed to support accelerated vaccine development, manufacturing, and roll-out for various outbreak scenarios to achieve the 100 Days Mission. The framework outlines coordinated deliverables across five functional areas: manufacturing processes, formulation, analytics, supply chain, and facilities. It could serve as a tool to streamline CMC and the related activities for rapid vaccine development, identify areas for improvement and innovation, and assess preparedness for the outbreak response. The framework emphasizes the importance of thorough preparation during interpandemic periods as the foundation for the 100 Days Mission and for gaining the confidence of health authorities and the public in vaccines.
