The speculation that the MMR shot was causing Autism back in the 90's was due to the fact that the drug companies were producing large quantities of the shot and therefore had to use a preservative.....that way the Dr.'s office could keep it on the shelf longer....purchasing the large amounts of the shot. The preservative contained mercury in it.....I do not think this is being used any longer....my child recieved the MMR in 1996/7 and hers did contain the preservative, and she is high functioning autistic. No one will admit that the MMR caused the autism, they have linked the autism outbreak during that time period soley to the preservative. So....if you find a Dr. office that will give the shot separately, you might want to inquire about whether or not the MMR still contains a preservative to give it a longer shelf life? Good luck.
