Final most dominant escape variant is shown (i.e. frequency of occurrence >70%).
Red shows the positions which undergo amino acid change.
IFN-γ ELISPOT test of autologous PBMC measured in SFU per million PBMC against wild type epitope at earliest sample time point with a positive assay (shown in DPI column). WT - Wild Type and MT - Mutant Mutant epitopes are sourced from the final available deep sequenced data point.
Days post infection.
The epsilon estimate is the rate of escape given in per day.
