My son was diagnosed with this last year. He has had multiple vaccinations. What are the actual numbers of how many Americans have this? Is there any work being done on finding a cure? Are there any ongoing studies? I know a little girl who has the same thing and she has had problems with her urinary tract but my son only had problems with his ears, nose and throat. Are these differences common? Any information would be greatly appreciated. Its very frustrating having so many questions and not many answers.
