Correct answer: B — Give two age-appropriate doses separated by at least four weeks

Influenza vaccine is recommended beginning at 6 months of age. A child from 6 months to under 9 years who has not previously received at least one seasonal influenza vaccine dose needs two age-appropriate doses in the current season, with a minimum interval of four weeks. Thereafter, one dose per season is generally recommended. The specific product must be authorized for the child's age; live attenuated intranasal vaccine is not used in a 6-month-old. The original broad six-month vaccine bundle was not reliable because routine infant schedules differ among provinces and territories and may vary by vaccine product. This revised objective tests a stable national NACI schedule rather than a jurisdiction-dependent bundle.
