I truly feel that as more and more people start to take
Tysabri, there will be more and more cases of
PML, as well as other serious complications and side effects. It just stands to reason...
There's still also the risks for serious liver damage, as well as the FDA now having Tysabri on it's watch list because of melanoma. There have been at least 2 cases of that this year, both after only being on Tysabri a very short time.
