• Isolated right hypoglossal (12th) nerve paralysis occurred after bivalent killed influenza vaccine (types A and B) immunization of a 7-month-old girl with cystic fibrosis. Two days after the third immunizing dose, fever and right hypoglossal paralysis developed. There were no other neurologic signs, and she recovered completely over the following three months.
