For each serogroup, the 4-fold rise is defined as:
a post-vaccination hSBA titer equal to or higher than (=) 16 for participants with a pre-vaccination hSBA titer <4;
a post-vaccination hSBA titer = 4 times the LLOQ for participants with a pre vaccination hSBA titer = limit of detection (LOD) but < LLOQ; and
a post-vaccination hSBA titer = 4 times the pre-vaccination titer for participants with a pre-vaccination hSBA titer = LLOQ

or other immune-modifying drugs during the period starting 3 months prior to any
vaccine/product dose until the following post-vaccination blood sample. For
corticosteroids, this will mean prednisone equivalent =20 mg/day for adult
participants and =0.5 mg/kg/day with maximum =20 mg/day for pediatric participants.
Inhaled and topical steroids are allowed.
15. Concurrently participating in another clinical study, at any time during the study
period, in which the participant has been or will be exposed to an investigational or
a non investigational vaccine/product (drug or medical device).
16. Child in care.
17. Pregnant or lactating female.
18. Female planning to become pregnant or planning to discontinue contraceptive
