VAXBaby 40: Can vaccines cause food allergies?

Did you know that before vaccines were invented, we didn’t even have the word allergy? Before we started injecting foreign material into our bodies, there wasn’t a word for anaphylaxis?

Isn’t that interesting? How did these words enter into our vocabulary? Allergy is described as “a condition in which the immune system reacts abnormally to a foreign substance.” Anaphylaxis describes a very severe allergic reaction to something. It can be life threatening.
