What: "Think of it this way. If you had never seen poison ivy before and no one had told you that poison ivy is harmful, you not know to avoid it or that it is a good idea to remove it from your yard until you touch it and get the rash. Immunization is like someone showing you what poison ivy looks like and shows you what happens to people who come in contact with it. You know BEFORE coming across the real thing that it is bad and you know what to do."
