Excludes VP1 as the attenuating locus in type 3 Sabin virus; leaves open other genomic sites for mapping in vaccine research.
The molecular basis of attenuation of type 3 Sabin vaccine virus does not involve the VP1 polypeptide, unlike type 1 poliovirus.
Stanway et al. (1983) studied this question.
