Safety and Immunogenicity of GSK Bio's Candidate HBV-MPL Vaccines Compared to Engerix™-B, in Healthy Adolescents
Study to Assess the Feasibility of GSK Bio's Candidate HBV / MPL Vaccines Following Different Schedules and Formulations and to Compare Their Safety and Immunogenicity to That of Engerix™-B in Healthy Adolescents Aged 11 to 15
In this study the safety and immunogenicity of 2 different formulations of the candidate HBV-MPL vaccine administered according to a 0, 6-month schedule were explored and compared to that of Engerix™-B in healthy adolescents aged 11 to 15
At the time of conduct of this study, the sponsor GlaxoSmithKline was known by its former name SmithKline Beecham
