Several hours after receiving an intramuscular vaccine injection to the leg, the 2-year-old female developed persistent localized leg pain and limping. While attempting to walk and expressing pain, she acutely became pale/gray with brief bluish discoloration, lost muscle tone, and was minimally responsive for approximately 2?4 minutes. No rhythmic movements, eye deviation, incontinence, tongue biting, rash, wheezing, or swelling were observed. She gradually regained color and responsiveness without intervention and returned to baseline behavior afterward, though appeared briefly fatigued and distressed. Emergency evaluation showed oxygen saturation 98%, heart rate approximately 120 bpm, normal EKG, and normal doctor exam. The event resolved spontaneously without sequelae.
