A 12-month-old child with a documented egg allergy (hives after egg ingestion) is due for MMR vaccination. Which of the following is the MOST appropriate approach?
- A Administer MMR in a hospital setting under observation; egg allergy (including anaphylaxis) is NOT a contraindication to MMR ✓
- B Withhold MMR vaccine; it is absolutely contraindicated in egg allergy
- C Substitute with a single-antigen rubella vaccine to avoid exposure to egg-grown components
- D Skin test with MMR vaccine; if positive, desensitize before administering
Explanation
MMR vaccine is grown in chick embryo fibroblasts, not egg albumin, and contains negligible egg protein. Current guidelines (IAP and ACIP) state that egg allergy—even a history of anaphylaxis to egg—is NOT a contraindication to MMR vaccination. The vaccine can be given in the standard setting; however, for children with severe egg anaphylaxis, a 30-minute observation period in a facility equipped to manage anaphylaxis is prudent. Skin testing prior to MMR is not routinely recommended and skin testing with vaccine does not reliably predict anaphylaxis. Influenza vaccine (grown in egg) requires more caution than MMR.
