Persistence of Antibody Levels and Response to Fifth or Third Meningococcal B Recombinant Vaccine in 4-year Old Healthy Children Who Previously Participated in Study V72P12E1

It is a Phase 3 extension of study V72P12E1 (NCT00944034). The main aim of the second extension study is to explore the bactericidal antibody persistence in 4-year-old children after a fourth dose boost of rMenB+OMV NZ or after a two-dose catch-up schedule of rMenB+OMV NZ administered to toddlers as part of their respective vaccination courses in study V72P12E1.

In addition, this study will characterize the antibody response to a fifth dose boost in all children who received a three-dose primary series of rMenB+OMV NZ at 2, 3, 4 months of age (in parent study V72P12, NCT00721396), and only in a subset of children who received a three-dose primary series of rMenB+OMV NZ at 2, 4, 6 months of age (in parent study V72P12). Antibody response will also be characterized to a third dose boost of rMenB+OMV NZ administered at approximately 4 years of age in all children who received a two catch-up doses of rMenB+OMV NZ as toddlers in study V72P12E1.

Finally, the safety and immunogenicity of two catch-up doses of rMenB+OMV NZ administered 2 months apart to healthy naïve children at 4 years of age will be assessed.
