Towards Integrated Continuous Viral Vaccines Production Using Two-Stage Bioreactor Systems, Felipe Tapia
Cell Culture Engineering XV
Typically, many cell culture-derived viral vaccines are being produced in batch processes. However, with increasing demands of a growing world population for potent, safe and affordable vaccines, manufacturing technologies need to be further optimized. In particular, the establishment of two-stage bioreactors appears as an interesting option for continuous production of viral vaccines. In these systems cell growth and virus propagation are being performed in separated vessels [1], which make them suitable for production of lytic viruses, such as influenza and Modified Vaccinia Ankara virus (MVA). MVA virus has received much clinical attention, because it is as a promising vector candidate …

Integrated Continuous Biomanufacturing II
Continuous processes can be particularly efficient for production of biologicals that are required in large amounts such as viral vaccines. One virus that has received much clinical attention is Modified Vaccinia Ankara virus (MVA), which is a potential platform for expression of recombinant viral antigens and can be used as a vector in gene therapy [1]. Recently, a new MVA virus strain has been successfully propagated at high yields in non-aggregated avian suspension cells [2] allowing the production of MVA virus in continuous bioreactors. MVA is a lytic DNA virus and therefore, continuous production strategies can be implemented using two-stage …
