Brief Title
Immune Memory Foll Pry Vaccination With DTPw-HBV/Hib Vaccine Formulation; Immuno & Reacto of Booster Dose at 15-18 Mths
Official Title
Assess the Immunogenicity &d Reactogenicity of a Booster Dose of a Formulation of GSK Biologicals' DTPw-HBV/Hib Vaccine at 15-18 Mths of Age in Infants Previously Primed With the Same Vaccine
Brief Summary
To assess the anti-PRP antibody response one month after vaccination in the groups receiving a fourth consecutive dose of two formulations of DTPw-HBV/Hib vaccine
Detailed Description
All subjects were previously primed with one of the two formulations of the combined DTPw-HBV/Hib vaccine. At the age of 10 months, 50% of each group received a plain PRP challenge to assess the immune memory to PRP. In this booster study in the second year of life, all subjects who received DTPw-HBV/Hib and plain PRP will receive DTPw-HBV as a booster vaccination. All other subjects will receive as booster the same vaccine they received in the primary vaccination study.
