Eat organically grown plants, that's what I try to do mostly as a vegan. Good can be a part why there is are some health issues for some people.

If your child was fine, then they got vaccinated, then their ability to function was altered greatly afterwards, the logical conclusion is that the vaccine did something. Not that vaccines always do that, but it has happened to many children where parents can easily correlate the cause to a vaccine or several.

It's not food when a child was fine, interacting, then a vaccine(s), then their brain doesn't operate the same as before.

Thanks for the feedback.
