Allergies are a sign of an overactive immune system. As we talked about yesterday, what do vaccines do? They trigger an immune response. Which in turn, in susceptible children, triggers all sorts of things.
Why do you think that most elementary schools don't allow peanut butter anymore? Where were the anaphylactic ally allergic kids 30 years ago when we all ate PB&J for lunch? Those allergies are compliments of vaccination.
