入选标准

  • ≥6months to ≤35 months-old healthy children (male or female) born at term after normal pregnancy
  • Recording of medical history and physical examination reveal no abnormality
  • The parent/legal guardian of the participating child must sign the written informed consent and agree to provide a blood sample taken from the child pre- and post-immunization

排除标准

  • Hypersensitivity to eggs, chicken proteins, polymyxin B, neomycin or any component of the vaccine
  • Previous vaccination against influenza
  • At time of enrollment, presentation of clinical symptoms of active infection and/or body temperature ≥38°C
  • Confirmation or suspicion of immunosuppressed status (including cancer), or confirmation of immunodeficiency disease (congenital or acquired including HIV)
  • Medical treatment (>2 weeks) with immune suppressant or immune modulating drugs including systemic steroids during the last 3 months before immunization or at present, as follows: long-term oral prednisone or other equivalent steroid: ≥0.5mg/kg/day (note: administration of local or inhaled steroids before or during the study is allowed)
  • Treatment with immunoglobulins or blood products during the last 3 months before immunization or such treatment scheduled during the study
  • Participation in other clinical trials during the last 3 months before immunization or intention to participate during this study period
  • At present or during the last 6 months before immunization: radiotherapy or treatment with cytotoxic drugs
  • Other vaccination with a killed vaccine within 14 days before immunization or with an attenuated vaccine within 28 days before immunization (note: after subject inclusion vaccines of the immunization program for children are allowed upon the physician's discretion. However, immunization on the same day must be avoided)
  • Family history of Guillain-Barré Syndrome
  • Severe congenital deficiency or disease
  • Antecedent of neurological disease or epileptic attack
  • Severe cardiopulmonary disease with possibility to influence the study result
  • Disturbance of coagulation or under anticoagulant treatment, likely to be contraindicated to i.m. injection
  • Suspected non-compliance

结局指标

主要结局

Immunogenicity, Assessed by the Haemagglutination (HI) Test

时间窗: 3 weeks after the 2nd vaccination

Seroconversion rate post-immunization. Seroconversion is defined as a post-vaccination titer of ≥1:40 for those with a pre-vaccination HI titer of \<1:10 and as ≥ four-fold increase in HI titer for those with a pre-vaccination HI titer of ≥1:10.

次要结局

  • Fold Increase in Geometric Mean Titer (GMT)(3 weeks after the 2nd vaccination)
  • Safety: Incidence of Solicited and Unsolicited Adverse Events(Solicited AEs: Days 1-4 and 28-31, and Days 28 and 49; unsolicited AEs: until study end)
  • Seroprotection(3 weeks after the 2nd vaccination)
