“Expanding the capability of our PeliCRM197^® franchise with Intravacc now creates a full-service solution for our early-stage customers and partners needing vaccine conjugation development. With both companies having direct product experience in preclinical, manufacturing, and clinical development, the combined know-how of the two firms fills a gap that is needed by the vaccine industry as a whole."

This partnership harnesses the synergistic strengths of both companies, fostering innovation and efficiency in vaccine development. Intravacc contributes its comprehensive technical expertise, state-of-the-art facilities, and robust capabilities in antigen conjugation process development, scale-up, and GMP production of conjugate vaccines.
