[QUOTE=Grammie 2 3;570658]My daughter in-law found some info that I wanted to pass along. Not much different except when you click on "Info For Health Care Professionals" it states minimal chance for pml after 35 infusions.

The FDA stated that there is limited experience past 35 infusions. No way to tell what the risk is past 35 infusions until more patients have taken the drug for that long.
