This story reminds me of how in the late 80s a couple of scientists discovered that stomach ulcers are, in most cases, caused by a specific bacteria.

It wasn't until 10 years later that it became the regular treatment.

What I love about the MS story, is that a) it's obviously a far more serious disease, b) if this works, it's relatively simple to cure c) and makes an ENORMOUS difference to so many people!
