Abstract__ Background Live attenuated measles virus MeV vaccine strains were generated by adaptation to cell culture. The genetic basis for the attenuation of the vaccine strains is unknown. We previously reported that adaptation of a pathogenic wild-type MeV to Vero cells or primary chicken embryo fibroblasts CEFs resulted in a loss of pathogenicity in rhesus macaques. The CEF-adapted virus D-CEF contained single amino acid changes in the C and matrix M proteins and two substitutions in the shared amino terminal domain of the phosphoprotein P and V protein. The Vero-adapted virus D-VI had a mutation in the cytoplasmic tail of the .
