I'm trying to find out the same information you are. My son is 2 1/2 and has absolutely no signs or symptoms, but I am leary of getting the vaccine. I live in NJ where the chances of a boy getting autism is 1 in about 25. I'm going to eventually have to get it for him. Someone else had mentioned the same recommendation that Sadiegirl stated about getting the vaccines seperately. I don't know the reasoning behind it, though. I can't find a source that will tell me to what age children are developing / or getting diagnosed with this. I'm also curious as to whether or not they had symptoms before their vaccination.
