It seems you would get a lot more mercury in 3 then in one. As I understand it, the big study that was done recently came out against the vaccines, and corroborated a positive link with autism, then afterwards some of the scientists backed down and denied the findings, except for the leader of the group, I think. He wouldn't budge. Somebody got to the others.
"Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality." 1
"The scientists from Franklin to Morse were clear thinkers and did not produce erroneous theories. The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane."2
A famous homeopathic physician, Dr. Moskowitz (spelling?) has treated cases of autism with a homeopathic remedy related to the vaccines which basically neutralizes the effects, and reportedly cured them. If this is so, something entirely different may be going on...something reversible.
