Symptom narrative

Nurse was administering a Kinrix PFS IM in the left deltoid when the child moved and the needle came out with only half of the vaccine injected. The nurse recapped the needle for safety and proceeded to administer Proquad SQ without incidence. The nurse then brought the Kinrix out of the patient room discussed with other staff members and put a new needle on the syringe and gave the remaining volume IM in the right deltoid. Once the nurse manager was available, she informed her of incident. The nurse manager immediately let the nurse know that she will contact the immunization branch for guidance. The branch called back the following day to advise that this is an administration error. The patient would need a repeat dose with no minimal interval required and that this was also a contamination/infection risk and would need to be reported to VAERS. The PCP was informed upon return to office and then parents notified. Parents did not express any side effects at the time of notification.
