Anaphylaxis Provoked by Bovine Gelatin Caused by Ingestion of Jelly Candy and Using Hair Gel.

Gelatin, a product obtained by the partial hydrolysis of collagen, is widely used in foods and pharmaceuticals. In the past, most commercially available vaccines, both live and inactivated, contained gelatin as a stabilizer, and allergic reactions to gelatin contained in measles, mumps, and rubella vaccine were reported. However, gelatin-allergy to foods was thought to be rare. It was unknown what factors predisposed recipients to vaccine-related gelatin allergy. There can be a genetic predisposition to gelatin allergy. We report a patient who experienced anaphylactic reaction on ingestion of jelly candy containing bovine gelatin and using hair gel.
