Gelatin in Vaccines Can Cause Allergic Reactions

The substance known as “gelatin” is a protein usually obtained from cows or pigs and produced by the partial hydrolysis of collagen extracted by boiling animal parts such as cartilage, tendons, skin, bones and ligaments in water. It acts a stabilizer, thickener and texturizer in food products such as yogurt, cream cheese, ice cream, marshmallows, etc. It is also used in the manufacturing of vitamin and drug capsules and cosmetics and is an ingredient in vaccines. According to the U.S. Centers for Disease Control and Prevention (CDC) vaccine excipient list, eleven vaccines contain gelatin. Gelatin is used as a stabilizer in vaccines and primarily comes from pigs. Gelatin is the most commonly identified cause of allergic reactions to vaccines
