Filter by:This study was designed to assess the lot comparability of DAPTACEL, as well as the safety and immunogenicity of DAPTACEL when co-administered with other recommended infant vaccines. Stage I Primary Objectives: 1. To assess the lot-comparability of immunogenicity of DAPTACEL by when co-administered with other recommended vaccines. 2. To compare the immune response to DTaP-IPV/Hib (Pentacel) with those of three lots of DAPTACEL when co-administered with other recommended vaccines. 3. To compare the immune response of PRP-T antigen in Pentacel with that of ActHIB concurrently administered in a different injection site with DAPTACEL when these vaccines are co-administered with other recommended vaccines. Stage II Primary Objectives: 1. To compare the immune response of DAPTACEL when the 4th dose is co-administered with Hib or other infant vaccines. 2. To compare the the immune response of Pentacel with those elicited by DAPTACEL when co-administered with ActHIB in toddlers.
This is a follow-up of Study A3L11 (NCT00404651). Immunogenicity - To describe the antibody persistence following a primary series vaccination of either DTaP-IPV-Hep B-PRP~T or Infanrix hexa™. - To describe the immunogenicity of a booster dose of DTaP-IPV-HepB-PRP~T in a subset of subjects. Safety - To describe the safety profile after a booster dose of DTacP-IPV-HepB-PRP~T.
Subjects aged 9 to 13 years who participated in the 711866/001 study 5 years ago will be evaluated for immune persistence and will receive a combined dTpa-IPV booster dose that will be evaluated in terms of immunogenicity, safety and reactogenicity.
The purpose of this booster study is to evaluate, in subjects primed in the primary study 106786, the persistence, at the time of the booster vaccination, of antibodies elicited by the different formulation of DTPa-HBV-IPV/ Hib vaccine (Infanrix Hexa TM). The study will also evaluate the immune response of these subjects to a DTPa-HBV-IPV/Hib booster. This protocol posting deals with the objectives and outcome measures of the booster phase. The objectives and outcomes measures of the primary phase are presented in a separate protocol posting (NCT = 00376779).
This is a follow-up of Study A3L10 (NCT00315055) Immunogenicity - To describe the antibody persistence following a primary series vaccination of either DTaP-IPV-HB-PRP~T or PENTAXIM™ and ENGERIX B®. - To describe the immunogenicity of a booster dose of DTaP-IPV-HB-PRP~T. Safety - To describe the safety profile after a booster dose of DTaP-IPV-HB-PRP~T.
The purpose of this study is to evaluate the safety and immunogenicity of an indigenously developed liquid pentavalent (diphtheria, tetanus, pertussis, hepatitis B and Hib) combination vaccine in healthy Indian infants as a part of the routine immunization in accordance with the EPI schedule.
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.
To compare the seroprotection rates and booster responses to Canadian-manufactured Tetanus and Diphtheria Toxoids Adsorbed vaccine to the seroprotection rates and booster responses to the US-manufactured Tetanus and Diphtheria Toxoids Adsorbed vaccine when administered to subjects ≥ 60 years of age. To compare the post-vaccination geometric mean titers of antibody (GMTs) to Canadian manufactured Tetanus and Diphtheria Toxoids Adsorbed vaccine to the post-vaccination GMTs to the US manufactured Tetanus and Diphtheria Toxoids Adsorbed vaccine when administered to subjects ≥ 60 years of age.
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).
