The need to avoid using primates has prompted the replacement of primary monkey kidney cells (PMKC) as a substrate for oral polio vaccine (OPV) production. Here, we report on OPV produced on MRC-5 cells using an industrial process capable of producing over 1 billion doses. All serotypes produced on MRC-5 cells proved satisfactory in the monkey and transgenic mice neurovirulence tests. All the type 3 MRC-5 lots tested by Mutant Analysis by PCR and Restriction Enzyme Cleavage (MAPREC) had a 472-C content below the acceptable limit and similar to that of PMKC derived lots. The safety/reactogenicity and immunogenicity profiles following vaccination in infants and children were similar for OPV MRC-5 and OPV PMKC vaccine lots. Excretion rates and prevalence of revertants for the three serotypes following vaccination were also similar for both vaccines. These data support the use of MRC-5 cells as an alternative to PMKC for OPV production.
