Primary outcomes

  1. Number of Subjects Reporting Any and Grade 3 Solicited Local Adverse Events (AEs)

    Time frame: Day 0-6

    Grade 3 ecchymosis, redness and swelling were ≥ 100 millimeters (mm) and grade 3 pain was considerable pain at rest that prevented normal everyday activities. Any was >20 mm for ecchymosis, redness and swelling.

  2. Duration of Solicited Local AEs

    Time frame: Day 0-6

    Duration was defined as number of days with any grade of local symptoms.

  3. Number of Subjects Reporting Any, Grade 3 and Related Solicited General AEs

    Time frame: Day 0-6

    Any fever was defined as oral temperature ≥38.0 degree centigrade (°C), grade 3 fever was oral temperature ≥ 39.0°C. For other symptoms, any was defined as occurrence of any general symptom regardless of intensity grade or relationship to the study vaccination, grade 3 was defined as a general symptom that prevented normal activity. Related arthralgia, fatigue, gastrointestinal symptoms, headache, myalgia, shivering and fever were defined as general symptoms assessed by the investigator as causally related to the study vaccination.

  4. Duration of Solicited General AEs

    Time frame: Day 0-6

    Duration was defined as number of days with any grade of general symptoms.

  5. Number of Subjects Reporting Any, Grade 3 and Related Unsolicited AEs

    Time frame: Day 0-20

    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. Any was defined as occurrence of any unsolicited symptom regardless of intensity grade. Grade 3 was defined as an unsolicited symptom that prevented normal activity. Related was an event assessed by the investigator as causally related to the study vaccination.

  6. Number of Subjects Reporting Any, Grade 3 and Related AEs With a Medically Attended Visit (MAEs) During Day 0 to Day 20

    Time frame: Day 0-20

    For each solicited and unsolicited AE the subject experienced, the subject was asked if they had received medical attention defined as hospitalization, an emergency room visit or a visit to or from medical personnel (medical doctor) for any reason. Any was defined as occurrence of any symptom regardless of intensity grade, grade 3 was defined as a symptom that prevented normal activity and related was a general symptom assessed by the investigator as causally related to the study vaccination.

  7. Number of Subjects Reporting AEs of Specific Interest (AESI) Including Autoimmune Diseases From Day 0 to Day 20

    Time frame: Day 0-20

    AESI for safety monitoring are a subset of AEs that include both clearly autoimmune diseases and also other inflammatory and/or neurologic disorders which may or may not have an autoimmune etiology. Any was defined as occurrence of any symptom regardless of intensity grade.

  8. Number of Subjects Reporting Any and Related Serious Adverse Events (SAEs) From Day 0 to Day 20

    Time frame: Day 0-20

    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. Any was defined as occurrence of any symptom regardless of intensity grade and related was an event assessed by the investigator as causally related to the study vaccination.

Secondary outcomes

    Time frame: At Day 21

    A seroconverted subject was defined as a subject who had either a pre-vaccination titer < 1:10 and a post-vaccination titer ≥ 1:40 or a pre-vaccination titer ≥ 1:10 and at least a 4-fold increase in post-vaccination titer. The vaccine strains included A/Brisbane, A/Uruguay and B/Brisbane antigens.
