t necessarily have to stop
Tysabri at two years, dpeending on what his doctor says and what level of
risk he is willing to assume. We have one member here, Cosmobirdy, who just had her 42nd infusion, without a break, and is doing very well. If I were to continue past the two year mark I would be sure that the infusion center is doing a thorough screening each visit. There are interventions that can be done is PML is suspected early enough.
Also, has your friend had the JC Virus test?
