Th1 Th2 Th3
We have no scientific studies in infants, children or adults to help us understand the nature of the progression of TH1, TH2 and TH3 immune responses to any of the injected materials in vaccines.
Children are born with a cellular mediated immune system (TH1 cells – T-helper 1), a humoral immune system (TH2 cells – T-helper 2), and a regulator immune system (TH3 cells – T-helper 3) as major pieces of their overall immune systems. These three arms are immature when babies are born, and begin to mature as children are exposed to their environments through their nervous systems, skin, airways and intestines. Antibiotics, poor nutrition, stress, exposure to heavy metals and other environmental toxins, and the use of vaccines, may interfere with the proper maturing process of these three arms of children’s immune systems. In theory, if the TH system is allowed to mature, and is not interfered with, children will develop a mature, balanced TH1, TH2 and TH3 immune system by age three.
TH1 and TH2 develop to protect children from the outside world, producing inflammation and anti-inflammation responses to foreign particles from the natural environment. TH3 immune cells develop to keep the TH1/TH2 arms of the immune system in check so the body only produces the amount of inflammation and anti-inflammation that is needed to protect itself from exposures in the natural environment.
When TH2 cells are activated properly, either directly via the natural environment, or through a direct signal from the TH1 system, the B cell arm of the immune system is then stimulated, leading to the production of the desired protective antibodies.
It’s important for the reader to know that the hallmark of a healthy, mature immune system in children is demonstrated by an equal and balanced TH1, TH2 and TH3 immune response to the natural environment. TH1, TH2 & TH3 do not work independently, and require a very important synergistic relationship to function properly in our bodies. As soon as one or more of these three arms begins to over or under work in relation to the other, chronic illness begins to express itself.
Aluminum is placed in the vaccines to selectively target the up-regulation of the humoral arm (TH2 cells) of children’s immune systems, to drive the production of antibodies. The medical community leads us to "believe" that this production of antibodies is what imparts for children a protective nature against vaccine-preventable illnesses. Yet, this outcome may come at a cost.
