The brain’s immune system cells, once activated [by vaccination], begin to move about the nervous system, secreting numerous immune chemicals (called cytokines and chemokines) and pouring out an enormous amount of free radicals in an effort to kill invading organisms. The problem is–there are no invading organisms. It has been tricked by the vaccine into believing there are.
Unlike the body’s immune system, the microglia also secrete two other chemicals that are very destructive of brain cells and their connecting processes. These chemicals, glutamate and quinolinic acid, are called excitotoxins. They also dramatically increase free radical generation in the brain. Studies of patients have shown that levels of these two excitotoxins can rise to very dangerous levels in the brain following viral and bacterial infections of the brain. High quinolinic acid levels in the brain are thought to be the cause of the dementia seen with HIV infection.
The problem with our present vaccine policy is that so many vaccines are being given so close together and over such a long period that the brain’s immune system is constantly activated. This has been shown experimentally in numerous studies. This means that the brain will be exposed to large amounts of the excitotoxins as well as the immune cytokines over the same period.
Studies on all of these disorders, even in autism, have shown high levels of immune cytokines and excitotoxins in the nervous system. These destructive chemicals, as well as the free radicals they generate, are diffused throughout the nervous system doing damage, a process called bystander injury. It’s sort of like throwing a bomb in a crowd. Not only will some be killed directly by the blast, but those far out into the radius of the explosion will be killed by shrapnel.
Normally, the brain’s immune system, like the body’s, activates quickly and then promptly shuts off to minimize the bystander damage. Vaccination won’t let the microglia shut down. In the developing brain, this can lead to language problems, behavioral dysfunction, and even dementia. In the adult, it can lead to the Gulf War Syndrome or one of the more common neurodegenerative diseases, such as Parkinson’s disease, Alzheimer’s dementia, or Lou Gehrig’s disease (ALS).
