Ok I'm seeing these entries for Tysabri...... what is it?? and what do you mean by infusion? Is it easier to take then rebif or copaxone? when i say easier i mean i hate shots with a passion and there's nothing i'd rather do then forget that i have to take a shot 3 days a week (which i do by accident anyway because i have no memory ... hahaha more stupidity leaks). so anyway what is it?
