I tested negative for the JC virus, and was reassured my chances for PML are almost nil. I have met quite a few people on
Tysabri, and have heard nothing but
good things about it. People seem to do really well and feel good while taking it.
Good luck to you and your decisions. For me it wasn't an easy decision. Get lots of information. I had a good friend who is a NP look over the inset given, and she said it seemed fairyl safe to her.
