Dr. Wakefield says that vaccines cause autism and explains in detail why adjuvants used in vaccines to stimulate a TH2 antibody immune response causes an abnormal overload and stress on the immune system that leads to immune dysfunction, which can lead to a wide variety of chronic health problems. Vaccination bypasses the TH1 cellular responses (responsible for 80% of our immune function according to Dr. Toni Bark) yet the immune system works best when both TH1 and TH2 work synergistically together. Vaccination destroys the synergy of the immune system because injection bypasses normal route of entry (through the lungs, often times) whereby TH1 cell response is the first response to happen. An antibody response is not an indicator of immunity, only of an allergic response. Natural immunity and being vaccine free is the healthiest option for children.
