For oral consumption I would agree the medicines would be fine. They're not validated as there is a pattern of increased autism shortly after taking the vaccines.
As we can see why they claim the mercury level as an example is fine for oral consumption thus it's fine for injections. You have to admit that is ridiculous right?
