Filter by:The new formulation administered as a 4th consecutive dose will be compared to the current formulation of the vaccine in this partially double blind study. The study will be double-blind with respect to the two DTPa-HBV-IPV/Hib groups. The study will be open with respect to the DTPa-HBV-IPV group.
The purpose of this study is to assess the efficacy and safety of repeating dTpa booster in adults 10 years after previous booster vaccination with dTpa in a prior clinical study. Only subjects who received booster vaccination in the previous clinical study are eligible for participation in this study.
The purpose of this study is to assess the efficacy and safety of repeating dTpa booster in adults 10 years after previous booster vaccination with dTpa in a previous clinical study (NCT01267058). Only subjects who received the booster vaccination in a previous clinical study are eligible for participation in this study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007. No new recruitment will be performed in this booster phase (see inclusion criteria).
To evaluate the immunogenicity, persistence of antibodies and reactogenicity of GSK Biologicals' DTPa (INFANRIX) and dTpa (BOOSTRIX), when administered to subjects 18-20 months old, compared with not giving a booster DTP vaccine at 18-20 months. Study double blinded for the two DTP vaccines and single blinded for the control arm.
The purpose of this study is to evaluate the persistence of antibodies against all the vaccine antigens 1, 3, 5 and 9 years after an initial vaccination with Tdap, and also to assess immunogenicity and safety of another dose of Boostrix, administered in this study. This protocol posting deals with objectives and outcome measures of the extension phase. The objectives and outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00346073).
The purpose of this study is to assess the safety in terms of fever (rectal temperature) higher than 39 degree Celcius (°C) and the immunogenicity in terms of antibody response following a booster vaccination with pneumococcal vaccine GSK1024850A at 11 to 18 months of age in children previously primed with the same vaccines including a pneumococcal conjugate vaccine co-administered with a diphtheria, tetanus, acellular pertussis (DTPa)-combined and meningococcal serogroup C (MenC) or combined meningococcal serogroup C and Haemophilus influenzae type b (Hib-MenC) vaccine. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00334334).
This study will evaluate the safety and immunogenicity of a booster dose of GSK Biologicals' reduced antigen content diphtheria, tetanus, acellular pertussis (dTpa) vaccine - Boostrix in comparison with Chinese DT vaccine, in children 6-8 years of age.
This study will compare GSK Biologicals' DTPa/Hib vaccine to separately administered DTPa and Hib vaccines in Chinese infants 3, 4 & 5 months of age, in terms of safety and immunogenicity.
This study will evaluate the safety and reactogenicity of booster dose of GSK Biologicals' dTpa vaccine (Boostrix) in Chinese children at 6-8 years of age.
The current study will provide information for the use of Boostrix concomitantly with influenza vaccine in adults aged 19-64 years. This study will also provide safety and immunogenicity data in a cohort of adults aged greater than or equal to 65 years.
