Comparing Immunogenicity and Safety of Different Formulations of HBV-MPL Vaccine With Engerix™-B in Adults Aged 18-40 y - Full Text View

Sponsored by:	GlaxoSmithKline
Information provided by:	GlaxoSmithKline

Purpose

This study will evaluate the immunogenicity and safety of different formulations of the candidate HBV-MPL vaccine administered according to a 2-dose schedule and compare it to that of Engerix™-B administered according to a 3-dose schedule in order to determine the optimal dose of each component of the candidate HBV-MPL vaccine when administered at 0 and 6 months
