Immunogenicity & Safety Study of a Meningococcal Serogroup B Vaccine Given in a 3 Dose Schedule to Healthy Adolescents Aged 12-18 Yrs

Phase 2
Completed
Conditions
Infections, Meningococcal
Registration Number
NCT00137917
Lead Sponsor
GlaxoSmithKline
Brief Summary

The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of 3 doses of the meningococcal serogroup B vaccine when given, using either a 0-2-4 month or a 0-1-6 month schedule, to healthy adolescents aged 12-18 years; a control group will receive 2 doses of Havrix™ (0-6 months) and Meningitec™ (month 1).

Detailed Description

The study is open; however, vaccines given to study group at 0-1-6 months and to control group will be administered in an observer-blind manner. 3 blood samplings for antibody testing: before vaccination and one month after the second and third vaccine doses.
