Common questions about vaccines and food allergies are answered below in the FAQ section.

The Big Question

Given that vaccines artificially stimulate the immune system, is it possible to completely and predictably control the immune system's response to one or more vaccines?

As the FDA points out: Most drugs consist of pure chemical substances and their structures are known. Most biologics, however, are complex mixtures that are not easily identified or characterized.

Vaccines are chemically treated biologics; it is impossible to guarantee that different lots are the same. VaxCalc research has found that different lots of the same vaccine can have significantly different injury profiles.

Inducing food allergies in mice

Researchers have, for many decades, used injections of aluminum and pertussis toxin to induce food allergies in mice and rats.

Inducing food allergies in children

The very same ingredients used to induce food allergies in mice and rats are found in one of the most common childhood vaccines that almost every child in America receives 6 times according to the CDC's Birth - 18 Years Vaccination Schedule, first as a 5-dose series at age 2, 4, 6, 15–18 months, 4–6 years and one more time at 11-12 years old.

In 2011, the United States Institute of Medicine published Adverse Effects of Vaccines: Evidence and Causality. On page 65, it is noted that vaccines can induce IgE-mediated sensitization in some people. IgE-mediated allergic responses are the most widely recognized form of food allergy and are characterized by the rapid onset of symptoms after ingestion (reference).

Antigens in the vaccines that the committee is charged with reviewing do not typically elicit an immediate hypersensitivity reaction (e.g., hepatitis B surface antigen, toxoids, gelatin, ovalbumin, casamino acids). However, the above-mentioned antigens do occasionally induce IgE-mediated sensitization in some individuals and subsequent hypersensitivity reactions, including anaphylaxis.
