Maybe the best place to start on the vaccine issue (neuro-toxicity of aluminum hydroxide more specifically) is Forrest Maready. He is an investigative journalist who has built a staggering, (and frankly frightening) thesis on the history and delivery mechanism for the numerous immune and neurological illnesses connected to vaccination. He is also very rational and is clear where he knows he is speculating, and where there is evidence, but not proof.

One thing he does well is absolutely eviscerate the pathetic excuses and hand-wavy bullshit the medical establishment gives to pretend autism and a basket of auto-immune disorders don't comprise one of the worst epidemics in human history, and that it isn't growing at a horrific pace, which it SO clearly is. And also in breaking down the specific delivery mechanisms of the illnesses and why they are all attached to the same problem (metal poisoning), manifesting simply in different areas of the brain or body. Also explaining why, if the medical establishment refuses to look at anything *they* are doing as a potential cause, why we suddenly have an explosion of chronic, incurable, seemingly inexplicable diseases that require lifelong medication and have no concrete source.

The first book I read was actually his unpacking of the history of Polio, which I think is a really good foundation to build from. (the story of our first, mass metal poisoning — mercury)

"The Moth in the Iron Lung"

I've also read a few of his other books that more specifically tackle the topic of aluminum hydroxide and does an incredible job at sourcing the potential pathways and method of damage in the body.

"Crooked" is excellent, and I'm reading "The Autism Vaccine" right now.

I would recommend any if you want to dive down the rabbit hole on this topic.
