Re: Testing Tysabri patients for JC virus

Those who test positive have a reason to take a break.

That’s the first reply in this thread that makes sense to me from an investment standpoint and does not come across as a Tysabri tout by someone with a personal stake in how the drug performs.

I would suggest that, in due course, a high proportion of Tysabri patients who test positive for JC virus will indeed cease treatment with Tysabri, either temporarily or permanently. The only reason this hasn’t happened yet is that the JC test is relatively new and the sample size of patients for the issue discussed in this thread is small.
