Incorrect dose administered

Symptom narrative

Patient was given the Afluria prefilled syringe of 0.5ml. After the clinic was over and we were billing the vaccines we noticed that the prefilled syringes are only approved for 3 years and up and after further investigation the patient should have received only 0.25 ml from a multidose vial and not the 0.5 ml from the prefilled syringe. Patient in essence received a double dose of the flu vaccine. Called and left a voicemail for the patient's parents to give me a call back to relay the incident and to check on how the child is doing.
