Showing all: 2 variant(s).
|Mutation Type||OV: observed variant
RCR: replicative capacity reduced
SF: susceptible form
|Method||CD8 T-cell Elispot - IFNy, Longitudinal study, Other, Relative replication capacity assay|
|Note||Mutation K43R appeared at 91d post-screening, and was fixed by 175d post-screening by which time it was predominant (83%), indicating strong selection. No T-cell- or Ab-responses were detected against the mutant, and it was not a cryptic epitope, showing host-specific, non-adaptive immune selection pressures. The mutant was shown to be 12% less fit than the T/F virus over 3 comparative fitness passages until it was almost completely replaced by the T/F.|

|Mutation Type||OV: observed variant|
|Method||CD8 T-cell Elispot - IFNy, Longitudinal study, Other|
|Note||This mutation appeared alongside K43R at 670d post-screening.|
