My mother (aged 58) is on PegInt + RBV therapy. Initially she had 32 Lakh VL which dropped to ~250 after 4 weeks and we get her rechecked after 8 and 12 weeks and both times VL was NIL. She is in 19th week of therapy. Did she really need to complete 48 weeks or shorter duration is possible? Also to add she is IL28B C/C genotype.
