Patient presented to the office for a routine wellness visit and was due to receive Hepatitis A and Influenza vaccines. Two medical assistants entered the room to administer the vaccines while the patient?s mother was seated on the exam table holding the patient. This visit was for twins, and two Influenza vaccines and two Hepatitis A vaccines were drawn up in preparation. During administration, the medical assistants inadvertently administered two Influenza vaccines to one twin instead of one Influenza and one Hepatitis A vaccine. The error was identified immediately after administration, and the provider was notified promptly. The second sibling did not receive any vaccines at that time. Poison Control was contacted and provided with all relevant information, including vaccine types and doses administered. Poison Control advised that no serious adverse effects were expected and that the patient might only experience local soreness at the injection site. The parent was notified of the error. The patient remained stable following the event with no immediate adverse reactions observed, and the parent verbalized understanding of the situation.
