NAPLEX Question of the Day

A 9-month-old infant presents with her mother for catch-up immunizations in October. She was born at term and has grown well without chronic medical problems. She received DTaP-HepB-IPV, Hib, and PCV at 2 and 4 months but missed her 6-month visit. She has not yet received any influenza vaccine doses. There is no history of immunodeficiency, wheezing, or asthma, and she does not attend daycare. She has no medication or food allergies. The mother asks which vaccine would be most appropriate to administer today to protect her infant during the upcoming respiratory virus season.

Which of the following vaccines is most appropriate for this patient?
