There are analogies with that; you have to listen to the people first. They're the start. We have, for example, some situations.... Thalidomide is one example. Its history was ignored for some years. We also have things like fibromyalgia. We don't know exactly what causes it, yet we treat it and we do whatever we can to avoid what we suspect are exposures. Chronic fatigue syndrome is another example.
There are a lot of conditions where there are analogies that we could follow. We're seeing risk. People are telling us. I'm not a physician but I'm used to vigilance monitoring and surveillance. As pointed out, we don't have those kinds of mechanisms in place right now. We need to go to places as described by Dr. Bray. We could do a lot, but you have to work with people first and listen to them.
