It sounds to me as if they will just be swapping one antiviral therapy for another. Please correct me if I’m wrong.
They would be swapping one anti-viral therapy that requires a person to take three different expensive drugs at fairly precise intervals every single day (and if you get it wrong, it reduces effectiveness of the treatment or can actually be dangerous), and which have side effects, for an anti-viral treatment that in the majority of cases would only need to be given once, and then the person is treated for life (or at least until an actual cure comes along that destroys the virus).
