Abstract

Autoimmune hemolytic anemia is an uncommon manifestation in the pediatric age and is frequently associated with a previous viral or bacterial infection. The authors report a clinical case of warm autoimmune hemolytic anemia following vaccination with meningococcal-ACWY vaccine (Nimenrix®). The clinical presentation was mild and resolved without directed treatment. To our knowledge there are no published reports of this adverse reaction and it is not mentioned in the vaccine’s EPAR. This report aims to alert clinicians for this adverse event following meningococcal-ACWY vaccine. Patients should be instructed about the alarm signs and symptoms.
