Information has been received from a consumer concerning her 12 year old white son who on 8/14/97 was vaccinated with a 3rd dose of MMRII (lot 617553/0217D). In 2/98, the pt told his mother, "I haven't felt very good for a long time". It was reported that the child was evaluated for depression, at that time, but that "different doctors had different opinions as to the child's dx". His mother further reported that he had "problems with his legs that come and go", and that the child's current physician feels that the symptoms might be caused by a virus. It was also reported that the child is currently taking "low dose" prednisone. Follow-up information, received from a physician on 9/4/01, revealed that the pt is currently under evaluation for neuropathy and myopathy. It was reported that he is presently seeing both a neurologist and an endocrinologist, however, he is still in the process of being evaluated and "worked-up". The physician stated that they have not yet identified any etiology behind the neuropathy/myopathy, with the possible exception of hypothyroidism, which was identified in the child (timeframe/date unk) and which has been "corrected for a while". The reporter felt that there is "a possibility" that the neuropathy and myopathy are related to vaccination with MMRII, however, "cannot say this for certain".
