evidence: Evidence that Food Proteins in Vaccines Cause the Development of Food Allergies and Its Implications for Vaccine Policy [...] Nobel Laureate Charles Richet demonstrated over a hundred years ago that injecting a protein into animals or humans causes immune system sensitization to that protein. Subsequent exposure to the protein can result in allergic reactions or anaphylaxis. This fact has since been demonstrated over and over again in humans and animal models. The Institute of Medicine (IOM) confirmed that food proteins in vaccines cause food allergy, in its 2011 report on vaccine adverse events. The IOM’s confirmation is the latest and most authoritative since Dr. Richet’s discovery. Many vaccines and injections contain food proteins. Many studies since 1940 have demonstrated that food proteins in vaccines cause sensitization in humans. Allergens in vaccines are not fully disclosed. No safe dosage level for injected allergens has been established. As a result, allergen quantities in vaccines and injections are not regulated. Allergen quantities in vaccine excipients are also not regulated. It has been demonstrated that a smaller quantity of allergen is needed to cause sensitization than elicitation. It is well recognized that many currently approved vaccines have enough allergen to cause anaphylaxis. Therefore, they contain more than enough allergen to cause sensitization. Children today have fewer childhood infectious diseases.
