Heavy metals collect in the brain. I just read an article in the dr's office about that study out of Japan from last year where they were finding connections to heavy metal poisoning and over-vaccination. More concerned with the schedule than anything. The article on the study was positing whether these autists just need chelation therapy.
My buddy's next door neighbor had a child over 5 years ago, and that the infant was having trouble with a skin condition. My friend told his neighbor what had happened to another child with a skin condition he knew of after vaccination. That child had been diagnosed as on the spectrum after their shots. My friend had learned from that event that the likelihood of landing on the spectrum after injection was up to 7x greater if there were any autoimmune issues at the time of administration. Told him he should wait on shots til the skin condition cleared up.
The neighbor brushed it off and went ahead with the schedule and the next checkup got them shots anyway. Their kid was immediately affected and began to hurt themself. They knew it was the shots and were freaking out, as they were perfectly fine 5minutes before the appt. When they asked my friend for help, they directed them to chelation foods and supplements right away, but the neighbor was worried that, because the child had stopped eating after the jabs, they wouldn't eat the chelation foods.
2 weeks later the neighbor reported the child was virtually ONLY eating the chelation foods and they had to portion control or they'd eat too much and purge it. After 6 months of the chelation regimen their improvement was significant and around that time stopped the head-banging and other physical trauma. 3 years more and there was very little left to see of what they'd become from the injections. They're going to school and doing well know.
Chelation isn't the only answer, and sometimes no remedies effect any significant change over the short term, but they are a great start, and are beneficial for those not onnthe spectrum that have deceloped congnitive issues and long term flu or resporatory symptoms.
There are other things in these shots besides metals that can cause severe reactions, long term harm, and autoimmune issues, as well as harming our natural immune defense against cancers.
