PML Cases Now Reach 448

Postby HarryZ » Sat Mar 22, 2014 5:57 am

The number of Tysabri related PML cases has increased by 9 over the previous month, bringing the new total to 438. It isn't known if there are any deaths included in this figure.

These are the cases reported by Biogen and may not reflect the real number of PML cases encountered by MS patients using Tysabri.
