Just because it's approved for pediatric use, doesn't mean it isn't potentially deadly.
What exactly isn't potentially deadly? Sitting still?
EDTA chelation is extremely safe statistically. I am not denying EDTA could possibly be the cause, but it is unlikely.
The reason this is a story is because of the controversial "Evidence of Harm" mercury vaccination caused theory of autism.
I personally don't buy the mercury connection yet, but there is probably some research that should be pursued.
