Measles, mumps, rubella, varicella and influenza vaccination in children with acute food protein-induced enterocolitis syndrome triggered by egg.

Acute food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy characterized by the onset of delayed repetitive and projectile vomiting accompanied by other clinical manifestations such as pallor, hypotonia, lethargy, hypothermia and/or diarrhea (1). Acute FPIES can be classified as classic or atypical based on the absence or presence of sensitization to the trigger food (2).
