E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the antibody persistence 24 to 36 months after the
completion of the vaccination course, in subjects who participated in the
V72_28. |
|
E.2.2 | Secondary objectives of the trial |
Secondary Immunogenicity Objectives
-To evaluate the immune response at one month after a booster dose administered 24 to 36 months after completion of the vaccination course in the parent study (Groups A, C, E, G and I).
-To evaluate the immune response of two catch-up doses of rMenB+OMV NZ administered 1 month apart to naïve children (Group K, L and M).
Safety Objectives:
To assess the safety and tolerability of rMenB + OMV NZ when given as a booster dose administered 24 to 36 months after completion of the vaccination course in subjects who participated in the V72_28, and to assess the safety and tolerability of rMenB + OMV NZ when given as a two dose regimen (0, 1 month schedule) to naïve subjects. |

|
Evaluation of primary and/or secondary immunogenicity/efficacy
obj. requires testing of biological samples from study
subjects, which can only be completed after all samples are collected.
The last samples for analysis of primary and/or secondary
objectives will be taken at the last study visit. For the purpose of this
protocol, end of study is defined as completion of testing of
such biological samples, to be achieved no later than 8 months after
collection of the last biological sample. |
