Having followed MS research for decades, I'm not surprised in the least at this person's comments.
Just look at the CRABs, Tysabri and now the oral MS drugs to understand what this former pharmaceutical rep is talking about. I was told by a MS neuro in the mid 90's that the CRABs were pretty much useless yet they still continue to bring in billions of dollars to the drug companies. And Biogen's new test for the JC virus was done to try and dramatically increase the revenue of Tysabri.
It's all about the money, always has been and will continue to be. That's life!
