Fig. 2: Comparison of frequency of polymorphisms present in stools and culture-amplified virus isolates from four participants administered mOPV2.

Stools were collected at different times post vaccine administration. a Stool samples with viral titre above 4 log CCID50/g versus virus amplified in cell culture from those stool samples. b Stool samples with titre below 4 log CCID50/g versus virus amplified in cell culture from those samples.
