Primary Outcome Measures:
  • Serum Haemagglutination-inhibition (HI) Antibody Titer Against the Three Vaccine Strains [ Time Frame: Days 0 and 21 ] [ Designated as safety issue: No ]
    Titers were expressed as Geometric Mean Titers (GMTs). The three vaccine strains assessed included A/Solomon Islands, A/Wisconsin and B/Malaysia.


Secondary Outcome Measures:
  • Number of Subjects Seropositive for HI Antibodies Against the Three Vaccine Strains [ Time Frame: Days 0 and 21 ] [ Designated as safety issue: No ]
    A seropositive subject was defined as a subject with a serum HI titer greater than or equal to 1:10. The three vaccine strains assessed included A/Solomon Islands, A/Wisconsin and B/Malaysia.

  • Number of Subjects Seroconverted for HI Antibodies Against the Three Vaccine Strains [ Time Frame: Day 21 ] [ Designated as safety issue: No ]
    A seroconverted subject was defined as a subject who had either a pre-vaccination titer below 1:10 and a post-vaccination titer greater than or equal to 1:40 or a pre-vaccination titer greater than or equal to 1:10 and at least a four-fold increase in post-vaccination titer. The three vaccine strains assessed included A/Solomon Islands, A/Wisconsin and B/Malaysia.

  • HI Antibody Seroconversion Factors [ Time Frame: Day 21 ] [ Designated as safety issue: No ]
    Seroconversion factor was defined as the fold increase in serum HI GMTs post-vaccination compared to Day 0. The three vaccine strains assessed included A/Solomon Islands, A/Wisconsin and B/Malaysia.

  • Number of Subjects Seroprotected for HI Antibodies Against the Three Vaccine Strains [ Time Frame: Days 0 and 21 ] [ Designated as safety issue: No ]
    A seroprotected subject was defined as a suject with a serum HI titer greater than or equal to 1:40 that usually is accepted as indicating protection.

  • Number of Subjects Reporting Any and Grade 3 Solicited Local Symptoms [ Time Frame: During a 7-day period after vaccination ] [ Designated as safety issue: No ]
    Solicited local symptoms assessed include ecchymosis, pain, redness and swelling. Any: any symptom regardless of intensity grade. Grade 3 pain: considerable pain at rest, which prevented normal everyday activities. Grade 3 ecchymosis, redness and swelling: more than 100 millimeter.

  • Duration of Solicited Local Symptoms [ Time Frame: During a 7-day period after vaccination ] [ Designated as safety issue: No ]
    Duration was expressed as median number of days the symptom persisted. Solicited local symptoms assessed include ecchymosis, pain, redness and swelling.

  • Number of Subjects Reporting Any, Grade 3 and Related Solicited General Symptoms [ Time Frame: During a 7-day period after vaccination ] [ Designated as safety issue: No ]
    Solicited general symptoms assessed include arthralgia, fatigue, headache, myalgia, nausea, shivering and fever. Any: any symptom regardless of intensity grade; any fever: oral temperature greater than or equal to 38 degrees Celsius (°C). Grade 3: symptoms that prevented normal activity ; Grade 3 fever: oral temperature greater than 39°C. Related: symptom assessed by the investigator as causally related to the study vaccination.

  • Duration of Solicited General Symptoms [ Time Frame: During a 7-day period after vaccination ] [ Designated as safety issue: No ]
    Duration was expressed as median number of days the symptom persisted. Solicited general symptoms assessed include arthralgia, fatigue, headache, myalgia, nausea, shivering and fever.

  • Number of Subjects Reporting Any, Grade 3 and Related Unsolicited Adverse Events (AEs) [ Time Frame: During a 21-day period after vaccination ] [ Designated as safety issue: No ]
    Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms.

  • Number of Subjects Reporting Any, Grade 3 and Related Medically Significant Conditions (MSCs) [ Time Frame: During a 21-day period after vaccination ] [ Designated as safety issue: No ]
    Medically Significant Conditions (MSCs) included all unsolicited adverse events that resulted in a medically attended visit.

  • Number of Subjects Reporting Any and Related Serious Adverse Events (SAEs) [ Time Frame: During the entire study period (up to Day 21) ] [ Designated as safety issue: No ]
    SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject.
