The adverse event involved the administration of the incorrect vaccine (PCV20) to a patient who was due for the HPV vaccine. The error was identified during the verification process by the supervising provider; however, the vaccine was administered despite the warning. At the time of this report, the patient has not exhibited any immediate adverse symptoms or signs (e.g., fever, injection site reaction, allergic response). The patient was notified of the incident and is being monitored for any delayed reactions. The correct vaccine (HPV) has been rescheduled per provider recommendation. As a precaution, no specific treatment was required following the administration error. The incident was documented, and follow-up care instructions were provided to the patient/guardian.
