Thanks for note...
They have been infusing the MS folks for a while now....I think at least a year since it has come back on the market for MS...
I got a call the other week (in late August) from the Dr.'s office that did my first trial,...they called and asked if i would be willing to re-join the trial....I told them I was just about to try Humira. They felt it would be at least 2 or 3 months before the new protocol is issued. they said I could say yes now, but withdraw if the Humira worked ....if the Humira doesn't work then I stop taking it for 8 weeks and go back to the Tysabri when and if possible.
As for the prior issues...the best thing is to do a quick google or go to the Biogen website...the Elan website is just as good of a source for information as well.
