E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that the immune response of Vaxem™ Hib booster is non-inferior to the
immune response of comparator vaccine HIBERIX® booster as assessed by the
percentage of subjects with anti-PRP (polyribosyl-ribitol-phosphate) antibody levels
≥1.0μg/mL 30 days after booster vaccination. |
|
E.2.2 | Secondary objectives of the trial |
To demonstrate that the immune response of Vaxem™ Hib booster is non-inferior to the
immune response of comparator vaccine HIBERIX®booster, as assessed by the
percentage of subjects with anti-PRP antibody levels ≥0.15 μg/mL, 30 days after
booster vaccination.
To demonstrate that the immune response of Vaxem™ Hib booster is non-inferior to the immune response of comparator vaccine HIBERIX® booster, as assessed by anti-PRP antibody geometric mean concentrations (GMCs), 30 days after booster vaccination.
