Perils of childhood. Immunization against measles, mumps, and rubella.

Some children with a positive history and skin test for egg allergy require a unique desensitization protocol for the measles, mumps and rubella (MMR) vaccine. The pathophysiology of food allergies, skin testing and the MMR desensitization protocol are described. Strategies appropriate to the children's developmental stage are suggested to enhance the nurse's supportive role throughout the desensitization process.
