t what number did you get to when they said you have PML?

Very sorry ! I have been taking Tysabri for 3 years now and scared of PML :(

How long did you take Tysabri? Did you test positive for the Anti-JC virus? My fiance has MS and just tested positive for the virus but the doctor still wants to put him on it. Any advice?
