their child’s immune system could be weakened as a result of vaccination and almost as many felt that children were getting more immunizations than are good for them. Except for those who live in bubbles, we are continually exposed to bacteria, viruses, allergens and foreign proteins as part of daily living. The immune system can handle hundreds of thousands, if not millions of such challenges. For example, depending on the particular virus, we may be exposed to up to 10 foreign proteins during a single episode of an upper respiratory infection. A routine ’strep throat’ will present between 25 and 50 foreign proteins to the immune system. Modern vaccines are made of refined components of the organism, therefore actually present less of a challenge to the immune system than

an infection would.
