And you are just now bringing this to light?  How ironic because there was a very knowledgeable doctor in the UK by the name of Andrew Wakefield who brought this very thing up.  Only the powers that be did not want to hear what he had to say because they wanted to silence him for what he put in his published paper which by the way was also signed off by other medical doctors who were not punished I might add.  They stripped Dr. Wakefield's medical license and have been dragging his name through the mud for almost 2 decades even though he never once made claims of what they falsely accused him of doing.
