Why do you think Japan has a lower rate of side affects, including autism, then we do?
Maybe it’s because they don’t use aborted babies in their vaccines.

I would think American scientists, as well as parents, would want to study what Japan does.
It is most likely that autism is an inherited disorder, so it is not at all surprising that the rate of occurrence in a genetically homogenous and distinct population would be different (whether lower or higher).
The Japanese suicide rate is astronomical compared to that in the U.S. (and the leading cause of death in young and middle aged men). What shall we blame that on?
