| Main Objective: To demonstrate that ProQuad® can be administered concomitantly with a booster dose of Infanrix® hexa to healthy children 12 to 23 months of age without impairing neither the antibody response rates to measles, mumps, rubella, varicella, hepatitis B and Haemophilus influenzae type b, nor the 3 pertussis antibody titres as measured at 42 days following vaccination.;Secondary Objective: To describe the antibody titres and the antibody response rates to measles, mumps, rubella, varicella, diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b as measured at 42 days following vaccination when administered to healthy children 12 to 23 months of age, by Infanrix® hexa primary series schedule and for all data pooled. To evaluate the safety profile of ProQuad® when administered concomitantly with a booster dose of Infanrix® hexa to healthy children 12 to 23 months of age, by Infanrix® hexa primary series schedule and for all data pooled.;Primary end point(s): The primary immunogenicity criteria are the response rates to measles, mumps, rubella and varicella in Group 1 and Group 2 and to hepatitis B and Haemophilus influenzae type b in Group 1 and Group 3 and the antibody titres to the 3 pertussis antigens in Group 1 and Group 3 as follows: • The response rate for measles defined as the percentage of subjects with measles antibody titres ³ 255 mIU/mL in subjects whose baseline (BS1) measles antibody titre is < 255 mIU/mL, • The response rate for mumps defined as the percentage of subjects with mumps antibody titres ³ 10 ELISA Ab units/mL in subjects whose baseline (BS1) mumps antibody titre is < 10 ELISA Ab units/mL, • The response rate for rubella defined as the percentage of subjects with rubella antibody titres ³ 10 IU/mL in subjects whose baseline (BS1) rubella antibody titre is < 10 IU/mL, • The response rate for varicella defined as the percentage of subjects with varicella antibody titres ³ 5 gpELISA units/mL in s | — |
