Clinical Context
A 6-month-old infant presents to a primary care pediatric clinic during influenza season for routine vaccination. The child has no history of severe allergic reactions to influenza vaccine components, is up to date on well-child care, and has no current acute febrile illness. The clinical workflow: verification of patient identity and consent, review of immunization record and contraindications, screening questions for recent illnesses and allergies, preparation of the preservative‑free trivalent split-virus influenza vaccine 90655 in a 0.25 mL prefilled syringe, intramuscular administration (typically into the anterolateral thigh for infants), post‑administration observation for 15 minutes, documentation in the electronic medical record and state immunization registry, and billing using 90655. Typical site of service is an outpatient clinic, pediatric office, or community immunization clinic.
