Aspergers Syndrome wasn't a medical diagnosis till 1994. As far as a link to vaccines, you will find just as many studies to prove a link as there is against a link... so really I wouldn't fully put my money on either side. If measles caused autism... why aren't there a great deal more cases in the world? One big factor... genetics, something would have to trigger it... measles itself would not be the key factor, maybe a weakened immune system or something was it, but I highly doubt it myself. Actually just because someone has a temper and learned to be sociable, doesn't equate automatically to being autistic... it just doesn't work that way either.
