Primary objectives: inferential sequential analysis 1 month after the third vaccine dose (primary ATP cohort for immunogenicity)

Note : antigens sequenced by priority
PRP = polyribosylribitol phosphate; BPT = Bortedella pertussis ; HBs = Hepatitis B surface antigen
#Lower limit of the 95% CI
†Adjusted GMC = GMC adjusted for baseline concentration using ANCOVA model
Seropositivity rate = % subjects above cut-off
Group difference = % subjects in vaccine group above cut-off-% subjects in control group above cut-off
Group ratio = GMC vaccine group/GMC control group
