I would like to know what role quasi species plays in the treatment of
patients with HCV. My main question is whether repeated treatments using
the same type of interferon can later cause antibodies to develop against
alpha interferon itself. Also, will a change in brand name avert this problem if it is indeed one. I have been treated with Schering's version but have never managed to get my viral load undetectable. I have a normal liver enzyme level but I know that is not the entire picture.
