It really is a personal choice. I am not real familiar with Rebif but I was on Tysabri last year until my Neuro took me off of it in September after my 5th treatment. I think the odds of someone getting the PML Brain disease is really pretty low as long as your system is washed out of all of the other drug treatments you have been taking. They say you should go at least 3 months after you had a treatment before going on Tysabri. The people I talked to when I was getting treatments of Tysabri were very pleased with it and they all told me that it was working for them. If you have any questions about
it, I suggest you go to http://lauren-livingwithms-aolcomlglbgl2003.blogspot.com/ and email them to Lauren as she has been on Tysabri for a while and will try and answer any questions you have.
Good luck to you and God Bless you.
