Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Number of Seroprotected Subjects Against Diphteria (D) and Tetanus (T) Toxoid Antigens | At Month 1 post-Boostrix® vaccination | A seroprotected subject was defined as a vaccinated subject with anti-D and anti-T antibody concentrations equal to or above (≥) 0.1 International Units per milliliter (IU/mL), respectively. |
| Primary | Number of Subjects With Anti-T Antibody Concentrations ≥ the Assay Cut-off Value | At Month 1 post-Boostrix® vaccination | The assay cut-off value was ≥ 1.0 IU/mL, as assessed by enzyme-linked immunosorbent assay (ELISA). |
| Primary | Antibody Concentrations Against Pertussis Toxoid (PT), Filamentous Hemagglutinin (FHA) and Pertactin (PRN) Antigens | At Month 1 post-Boostrix® vaccination | Anti-PT, anti-FHA and anti-PRN antibody concentrations are presented as geometric mean concentrations (GMCs), expressed in ELISA units per milliliter (EL.U/mL). |
| Primary | Number of Subjects With Serum Haemagglutinin Inhibition (HI) Titers Against 3 Strains of Influenza | At Month 1 post-Fluarix® vaccination | The antibody titer cut-off value for the 3 influenza strains assessed (H1N1, H3N2 and B) was ≥ 1:40. |
| Primary | Number of Seroconverted Subjects Against Influenza Antigens H1N1, H3N2, and B | At Month 1 post-Fluarix® vaccination | Seroconversion for HI antibodies is defined as: For initially seronegative subjects: post-vaccination antibody titer ≥ 1:40 at Month 1 post-Boostrix® vaccination; For initially seropositive subjects: antibody titer at Month 1≥ 4 fold the pre-vaccination antibody titer. |
| Secondary | Number of Seropositive Subjects With Anti-D Antibody Concentrations Above the Cut-off Value | At Month 1 post-Boostrix® vaccination | A seropositive subject was a subject whose antibody concentration was greater than or equal (≥) to the cut-off value of 1.0 IU/mL. |

| Secondary | Number of Subjects With Booster Response Against Diphteria Toxoid (D) and Tetanus Toxoid (T) Antigens | At Month 1 post-Boostrix® vaccination | Booster responses for anti-D and anti-T antibodies are defined as: For initially seronegative subjects \[pre-vaccination concentration below (\<) cut-off 0.1 IU/mL\]: antibody concentrations at least four times the assay cut-off (post-vaccination concentration ≥ 0.4 IU/mL), one month after vaccination with Boostrix®; For initially seropositive subjects (pre-vaccination concentration ≥ 0.1 IU/mL): an increase in antibody concentrations of at least four times the pre-vaccination concentration, one month after vaccination with Boostrix®. |
| Secondary | Number of Subjects With Booster Response Against Pertussis Toxoid (PT), Filamentous Hemagglutinin (FHA) and Pertactin (PRN) Antigens | At Month 1 post-Boostrix® vaccination | Booster responses for anti-PT, anti-FHA and anti-PRN are defined as: For initially seronegative subjects (pre-vaccination concentration \< cut-off of 5 EL.U/mL): antibody concentrations at least four times the cut-off (post-vaccination concentration ≥ 20 EL.U/mL), one month after vaccination with Boostrix®; For initially seropositive subjects with pre-vaccination concentration ≥ 5 EL.U/mL and \< 20 EL.U/mL: an increase in antibody concentrations of at least four times the pre-vaccination concentration one month after vaccination with Boostrix®; For initially seropositive subjects with pre-vaccination concentration ≥ 20 EL.U/mL: an increase in antibody concentrations of at least two times the pre-vaccination concentration one month after vaccination with Boostrix®. |
