Genzel, Yvonne Reichl, Udo Esmeralda Gallo–Ramírez, Lilí Nikolay, Alexander Bioreactor concepts for cell culture-based viral vaccine production <div><p>Vaccine manufacturing processes are designed to meet present and upcoming challenges associated with a growing vaccine market and to include multi-use facilities offering a broad portfolio and faster reaction times in case of pandemics and emerging diseases. The final products, from whole viruses to recombinant viral proteins, are very diverse, making standard process strategies hardly universally applicable. Numerous factors such as cell substrate, virus strain or expression system, medium, cultivation system, cultivation method, and scale need consideration. Reviewing options for efficient and economical production of human vaccines, this paper discusses basic factors relevant for viral antigen production in mammalian cells, avian cells and insect cells. In addition, bioreactor concepts, including static systems, single-use systems, stirred tanks and packed-beds are addressed. On this basis, methods towards process intensification, in particular operational strategies, the use of perfusion systems for high product yields, and steps to establish continuous processes are introduced.</p></div> insect cells;strategy;product yields;reaction times;vaccine market;expression system;virus strain;antigen production;cell substrate;Numerous factors;perfusion systems;scale need consideration;Bioreactor concepts;cultivation method;process intensification;cultivation system;process strategies;vaccine production Vaccine manufacturing processes 2015-09-02
