Natural exposure to childhood infectious disease plays a very important role in children’s immunological development. The risk and fear of disease has parents and lawmakers running around trying to eradicate disease and mandate vaccines. What if you could gain exposure to these disease entities, produce a mild immunological response and learn from the experience without any attended side-effects?  This is the premise of Homeoprophylaxis (HP): the use of diluted pure infectious agents, delivered one at a time over several years during infancy and early childhood so as to gently and gradually develop normal healthy immune system responses. For this presentation Kate will look at the gifts of childhood infectious disease, outline the premise of HP, how it works in developing immune systems and compare and contrast the effects of vaccines and HP.
