Outcome Measures

Primary Outcomes (1)

  • Percent of Subjects Achieving Seroconversion Increased More Than 4-fold Versus Baseline for Antigens: Influenza Virus Type А - H1N1, Influenza Virus Type А - H3N2, Influenza Virus Type В - Yamagata and Victoria Lineage

    Percent of subjects achieving seroconversion (the number of volunteers with antibody titer \[of at least 1:40\] increased more than 4-fold versus baseline \[assessed by HAIR\]) for antigens: influenza virus type А - H1N1, influenza virus type А - H3N2, influenza virus type В - Yamagata and Victoria lineage, based on assessment at Visit 7.

    Day 21 after immunization (Visit 7)

Secondary Outcomes (9)

  • Geometric Mean of Serum Antibodies

    Day 21 after immunization (Visit 7)

  • Seroprotection: Percent of Subjects Achieving Protective Antibody Titer (1:40 and More) to Antigens H1N1, H3N2, Yamagata and Victoria Lineage, Based on Assessment at Day 21 After Immunization (Visit 7).

    Day 21 after immunization (Visit 7)

  • Incidence of Influenza and Acute Respiratory Infection (ARI)

    Day 180±5 after immunization (Visit 11)

  • The Average Value of the Total Duration of the Disease in Patients With Acute Respiratory Viral Infections or Influenza in Days .

    Day 180±5 after immunization (Visit 11)

  • Fold Change in Geometric Mean Titer of Serum Antibodies

    21 days following vaccination (visit 7).

  • +4 more secondary outcomes
