Inactivated polio vaccine: industrial production from micro-carrier Vero cells culture.

In 1980, we presented our preliminary results of large-scale production of Inactivated Polio-Vaccine (IPV). The virus was produced by Vero cells culture grown on micro-carrier in 150 litre tanks; now we produce the poliovirus in 1000 litre tanks. All the tests certifying the 'Cell Bank' have been passed; the quality of purification procedure was demonstrated; additional clinical studies were done; this new reassessed IPV was licensed in France in July 1982.
