(NaturalNews) Although many people are aware of the link between vaccines and cases of autism in children, what’s not so commonly known is the fact that vaccines also cause food allergies – and the Centers for Disease Control (CDC) has even corroborated the link in one of their own studies.

The 1999 study didn’t receive much attention at the time, but the results are clear: Food proteins such as gelatin used in the manufacture of vaccines can cause the development of sometimes life-threatening food allergies in children.

From the abstract of the CDC study:

“Most anaphylactic reactions and some urticarial reactions to gelatin-containing measles, mumps, and rubella monovalent vaccines are associated with IgE-mediated gelatin allergy. DTaP immunization histories suggest that the gelatin-containing DTaP vaccine may have a causal relationship to the development of this gelatin allergy.”

In layman’s terms, this simply means that gelatin-containing vaccines can cause gelatin allergies in those to whom they are administered.

Cases of children with food allergies are on the rise – around 8 percent of American children now suffer from them – but the link to vaccines has been generally under-investigated or ignored.

But more recent research has reconfirmed the link between vaccines and food allergies, including a study published in 2015 in the Journal of Developing Drugs.

Scientists have known about the link for more than 100 years

This study referred to decades of research confirming that food proteins, when injected intravenously, can indeed lead to the development of food allergies.
