And will we be able to afford them?

Look at the cost of Avonez, Copazone and Rebif. These drugs are not really proved to cure anything, just to delay relapses. I can't imagine the cost of a "cure" or a "vaccine". Pharm companies are making billions off of us...do they really want to "cure" or prevent MS? By helping us, they would lose the billions they depend on. I'm all for it, but highly sceptical.
