The EB66® cell line as a valuable cell substrate for MVA-based vaccines production.

The selection of a cell substrate is a critical step for the development and manufacturing of a viral vaccine candidate. Several parameters such as cell susceptibility and permissiveness to the viral pathogens but also performance in terms of viral antigens quality and production yields are important considerations when identifying the ideal match between a viral vaccine and cell substrate. The modified vaccinia virus Ankara (MVA) is a replication-deficient viral vector that holds great promise as a vaccine platform, however only limited cell substrates have been tested or are available for industrialization.
