Some of the live vaccines do contain gelatin as a stabilizing agent. Gelatin is an animal protein substance made from collagen obtained by boiling animal skins, hides, bones, and other tissues after pretreatment with alkali or acid. Gelatin is an ingredient in MMR, Varicella, and yellow fever vaccines. People with severe allergies to gelatin should consider skin testing prior to receiving a gelatin-containing vaccine. The problem is that most gelatins in foods come from boiled cows, while the gelatin used in vaccines is from boiled pigs.

"I am surprised at how comfortable GP’s seem to be sitting with any vaccination that has so little research on its components, especially in light of CJD. For example, both the FDA and Medicines Control Agency are reviewing the use of gelatin in pharmaceutical products in an attempt to minimise the risk, with the FDA actually banning its use in intravenous products. (7,8&9) However, they clearly think that there is a risk worth some consideration, so why are our GP’s being so dismissive? "---Carol A Teasdale
