Outcome Measures
Primary Outcomes (5)
Number of Participants Reporting Adverse Events by System Organ Class After Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or a Placebo Vaccine.
Day 0 through Day 60 post-vaccination
Number of Participants Reporting a Solicited Injection Site or Systemic Adverse Event After Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or Placebo Vaccine.
Solicited Injection Site Adverse Events: Erythema, Induration, Pain, Pruritus, Swelling, Rash. Solicited Systemic Adverse Events: Lymph Node Pain, Pyrexia (Temperature), Chills, Constipation, Diarrhoea, Fatigue, Headache, Malaise, Myalgia, Nausea, Vomiting, Alanine Aminotransferase Increased, Aspartate Aminotransferase Increased, Blood Creatinine Increased, Haemoglobin Decreased, Platelet Count Decreased, White Blood Cell Count Increased.
Day 0 through Day 7 post-vaccination
Number of Participants With Evaluated Laboratory Abnormalities After Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or Placebo Vaccine.
Day 0 through Day 60 post-vaccination 1
Number of Participants With Seroconversion to M2e Antigen During Initial Treatment and Follow Up Period After Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or Placebo Vaccine
Seroconversion was defined as an end point anti M2e antibody titer ≥ 100. Antibody responses were assessed by means of enzyme linked immunosorbent assay (ELISA)
Day 15 through Month 10 Post-vaccination 1
Geometric Mean Titers (GMTs) of Vaccine Antibodies After Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or a Placebo Vaccine.
Antibody responses to the respective vaccines were assessed by means of enzyme linked immunosorbent assay (ELISA). A GMT value of 50.0 indicates a titer at or below the lowest limit of quantitation (LLOQ)
Day 15 through Month 10 Post-vaccination 1
Secondary Outcomes (6)
Number of Participants With Signs and Symptoms of Influenza After Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or Placebo Vaccine.
Month 4 through Month 10 post-vaccination 1
Number of Participants With Seroconversion to M2e Antigen by Immunoglobulin G (IgG) Subclasses Before and Post-Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or Placebo Vaccine.
Day 0 and Day 60 Post-vaccination 1
Geometric Mean Titers of Anti-M2e Antigen by Immunoglobulin G (IgG) Subclasses Before and Post-Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or Placebo Vaccine.
Day 0 and Day 60 Post-vaccination 1
Geometric Mean Titer Ratios of Anti-M2e Antigen by Immunoglobulin G (IgG) Subclasses Before and Post-Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or Placebo Vaccine.
Day 0 and Day 60 Post-vaccination 1
Geometric Mean Titers (GMTs) of Anti-Hepatitis B Core Antibodies Using Immunoglobulin G (IgG) ELISA Before and Post-Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or Placebo Vaccine.
Day 0 and Day 15 through Month 10 post-vaccination 1
