I don't understand that statement. I had Hep C and it was cured with interferon/ribavirin. It was a nasty treatment and I guess there are people who don't complete it, hence (probably) its reputation for uncertain effectiveness.

I absolutely would have preferred this new treatment, but if you had been able to tell me five years ago that I could take interferon & ribavirin now, or wait five years for a better treatment, I still would have completed the interferon/ribavirin treatment.
