What Happens to the Brain With Vaccination?

It seems the brain is always neglected when pharmacologists consider side effects of various drugs. The same is true for vaccinations. For a long time no one considered the effect of repeated vaccinations on the brain.

This was based on a mistaken conclusion that the brain was protected from immune activation by its special protective gateway called the blood-brain barrier. More recent studies have shown that immune cells can enter the brain directly, and more importantly, the brain’s own special immune system can be activated by vaccination.

You see, the brain has a special immune system that operates through a unique type of cell called a microglia.

These tiny cells are scattered throughout the brain, lying dormant waiting to be activated. In fact, they are activated by many stimuli and are quite easy to activate. For our discussion, activation of the body’s immune system by vaccination is a most important stimuli for activation of brain microglia.

Numerous studies have shown that when the body’s immune system is activated, the brain’s immune cells are likewise activated. This occurs by several pathways, not important to this discussion. The more powerfully the body’s immune system is stimulated the more intense is the brain’s reaction. Prolonged activation of the body’s immune system likewise produces prolonged activation of the brain’s immune system.

Therein lies the danger of our present vaccine policy.

The American Academy of Pediatrics and the American Academy of Family Practice have both endorsed a growing list of vaccines for children, even newborns, as well as yearly flu shots for both children and adults. Children are receiving as many as 22 inoculations before attending school.

What Happens When the Brain’s Immune System is Activated?

The brain’s immune system cells, once activated, 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.
