The purpose of this study is to evaluate the antibody response to each of the three influenza vaccine strains included in the seasonal flu vaccine(AdimFlu-S), as measured by hemagglutination inhibition (HAI) at 4 weeks after two doses of study vaccine, 4 weeks apart, in infants between 6 and 12 months of age.

Primary Purpose: Prevention
||Clinical Study Protocol Immunogenicity and Safety of a Trivalent Inactivated Influenza Vaccine, Formulation 2010-2011， in Infants Aged Between 6-12months Old
Primary Outcome Measures:
- HA antibody titers will be determined using the WHO HAI reference technique. [ Time Frame: Serum samples will be obtained prior to vaccination (baseline), and 4 weeks after each vaccination. ]
Secondary Outcome Measures:
- The secondary objective is to evaluate the safety and tolerability profiles including the presence or absence of the pre-specified reactogenicity events and other serious/non-serious adverse events of the AdimFlu-S manufactured by Adimmune Corporation. [ Time Frame: (4 weeks after two doses of study vaccine, 4 weeks apart), Physical examination will be performed at each visit. Reactogenicity will be recorded for 7 days after each vaccination. ]
Safety data will consist of reactogenicity, serious and non-serious adverse events. Reactogenicity events are pre-specified adverse events systematically recorded for 7 days after each vaccination.
The events included fever (≥38.0°C), runny nose or nasal congestion, cough, sore throat, muscle aches, headache, vomiting, nausea and malaise. Furthermore, the local (injection site) reactions were also evaluated, including soreness/pain, swelling, redness, ecchymosis and limitation of arm motion.
