Viruses that mutate during vaccine production can lead to a less adequately prepared immune system. MDCK cells are the most suitable cell line for LAIV production as the virus yields are much higher and these cells have also historically been in use for the primary isolation of influenza viruses. In the bustling cell and gene therapy field, manufacturing is a major hurdle for drugmakers hoping to bring 10 to 20 new products to market each year in the coming decade. Regulatory agencies provide guidance for specific data for continuous cell lines (as they do for new cell lines).
