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.

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
Day 15 through Month 10 Post-vaccination 1

Seroconversion was defined as an end point anti M2e antibody titer ≥ 100. Antibody responses were assessed by means of enzyme linked immunosorbent assay (ELISA)

Geometric Mean Titers (GMTs) of Vaccine Antibodies After Vaccination With ACAM FLU A, or ACAM FLU A With Adjuvant, or a Placebo Vaccine.
Day 15 through Month 10 Post-vaccination 1

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)

Secondary Endpoints
