A 12-month-old child attends a private clinic for his first ever influenza vaccination, having never received one previously. As per IAP recommendations, what schedule should be followed?

• A Two doses separated by at least 4 weeks in the first year, then a single annual dose ✓
• B Single dose annually each year
• C Two doses separated by at least 8 weeks in the first year, then a single annual dose
• D Three doses in the first year, then a single annual dose

Explanation

Children between 6 months and 9 years receiving influenza vaccine for the first time require two doses at least 4 weeks apart in the first season, because priming with a single dose yields poor antibody response in this naive age group. From subsequent seasons, only one annual dose is needed. An 8-week gap or a three-dose series has no basis in IAP or AAP guidance.
