Filter by:This study is being conducted to assess impact of maternal immunisation against pertussis in infants ≤12 months of age before and after introduction of pertussis maternal immunisation in Bogota, Colombia from January 2005-December 2014.
The objective of this study is to assess the immunogenicity and safety of the DTaP-IPV combination vaccine compared with those of separate DTaP and IPV vaccines administered to healthy infants at 2, 4, and 6 months of age.
The purpose of this study is to assess duration of protection for GSK DTaP vaccines in preventing pertussis.
The purpose of this study is to describe the immunogenicity and safety of Sanofi Pasteur's DTaP-IPV-Hep B-PRP-T fully liquid combined hexavalent vaccine (Hexaxim®) administered at 2, 3, and 4 months of age and at 16 to 17 months of age in infants and toddlers who received a dose of Hep B vaccine at birth or within 1 week after birth. Primary Objective: - To describe the safety profile after each and all doses of Sanofi-Pasteur's DTaP-IPV-Hep B-PRP-T combined vaccine in Vietnamese infants and toddlers. Secondary Objective: - To demonstrate the non-inferiority of the immune response to all antigens induced by the study vaccine in Vietnamese infants one month after the third dose in a 3-dose primary series with the immune response to all antigens induced by the same study vaccine outside Vietnam. - To evaluate the immunogenicity of the study vaccine one month after the 3-dose primary series. - To describe the persistence of all antibodies before receipt of the booster vaccination. - To evaluate the immunogenicity of the study vaccine one month after the booster.
The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' Infanrix hexa, given in the primary vaccination schedule to infants born to pregnant women who participated in study 116945 [DTPA (BOOSTRIX)-047]. This study will help us evaluate if the presence of transplacentally transferred maternal antibodies interfere with the immune response to primary vaccination with Infanrix hexa and a co-administered pneumococcal conjugate vaccine given as a part of this study in infants.
The purpose of this study is to assess the immunogenicity and safety of Boostrix™ when compared to a placebo given during 27-36 weeks of gestation in healthy women aged 18-45 years. Infants born to mothers enrolled in this study will be followed-up in two separate clinical studies: 201330 [DTPA (BOOSTRIX)-048 PRI] and 201334 [DTPA (BOOSTRIX)-049 BST: 048].
Primary objective: - To demonstrate the non-inferiority in terms of seroprotection rates (Hib antigen (PRP), Diphtheria, Tetanus, and Pertussis antigens (PT and FHA), and polio types 1, 2 and 3 antigens) of investigational arm (Group A: DTaP-IPV/Hib) versus control arm (Group B: DTaP-IPV and Hib vaccines administered at separate sites), one month after the primary vaccination (all antigens). Secondary objectives: - To describe immune responses against all vaccine antigens with no pre-specified hypothesis, and at all time points (pre-dose 1, post-dose 3, pre-dose 4 and post-dose 4) in the two study groups (Group A and Group B). - To describe the safety after each dose of each vaccine in the two study groups (Group A and Group B). - To describe immune responses against all vaccine antigens with no pre-specified hypothesis, and at all time points (pre-dose 1, post-dose 3, pre-dose 4 and post-dose 4 (Group C)
This study is designed to assess the immunogenicity and safety of DTaP vaccine (BK1301) as a booster dose in adolescents. The purposes of this study are as follows: - To confirm the non-inferiority of BK1301 to Adsorbed Diphtheria-Tetanus Combined Toxoid (DT toxoid) with respect to booster responses for anti-diphtheria toxoid (anti-D) and anti-tetanus toxoid (anti-T) antibodies - To confirm that booster responses for anti-pertussis toxoid (anti-PT) and anti-Filamentous Hemagglutinin (anti-FHA) antibodies are more than 80% of participants received BK1301
The purpose of this study is to assess the immunogenicity and safety of GSK Biologicals' Infanrix hexa vaccine when administered to healthy infants as primary vaccination at 2, 4 and 6 months of age, co-administered with Prevnar and Rotarix with a booster dose of GSK Biologicals' Infanrix and Hiberix vaccines at 15-18 months of age.
The aim of this study is to evaluate the immunogenicity and safety of a novel DTaP-IPV-Hep B-PRP~T fully liquid combined hexavalent vaccine (study vaccine) administered at 2, 4, and 6 months of age compared to Sanofi Pasteur's DTaP-IPV//PRP~T combined vaccine (Pentaxim™) given at 2, 4, and 6 months of age and Hep B vaccine (Euvax B®) given at 1 and 6 months of age in South Korean infants that received a birth dose of Hep B and born to mothers documented to be serum anti-HBs Ag negative. Primary Objective - To demonstrate the non-inferiority in terms of seroprotection (Diphtheria, Tetanus, poliovirus types 1, 2, and 3, PRP-T, Hep B) and vaccine response for pertussis antigens (pertussis toxoid [PT] and filamentous haemagglutinin [FHA]) of Group A versus Group B, one month after the third dose of combined vaccines. Secondary Objectives: - To further study the immunogenicity of the two vaccination schemes, before the first dose and one month after the last dose of vaccines. - To study the safety after each and any dose of vaccines administered in the two vaccination schemes
