Filter by:In this study, the concentration of antibody to the vaccine one year, three and five years after vaccination in subjects who were vaccinated with GSK Biologicals' meningococcal vaccine GSK134612 in a previous study (whose objectives & outcome measures are presented in a separate protocol posting with NCT number =00471081) will be evaluated. The safety and immune response of a booster dose of vaccine GSK134612 administered at 5 years post-primary vaccination will also be evaluated. In addition, the immune response to a dose of vaccine GSK134612 administered to age-matched controls not previously given a meningococcal vaccine will be evaluated. This protocol posting has been updated further to protocol amendment 2, dated 28 october 2010. The sections impacted are summary, study design, outcome measures, intervention, and eligibility criteria.
In this study, the concentration of antibody to the vaccine one year, three and five years after vaccination in subjects who were vaccinated with GSK Biologicals' meningococcal vaccine GSK134612 and Menactra® in a previous study (whose objectives & outcome measures are presented in a separate protocol posting with NCT number =00454909) will be evaluated. The safety and immune response to a booster dose of vaccine GSK134612 administered at 5 years post-primary vaccination and a primary vaccination of a newly enrolled group with GSK 134612 vaccine will also be evaluated.
A study team with extensive experience in immunization delivery research will evaluate the effectiveness of vaccination reminder/recall systems for adolescent patients in five types of clinical settings including: urban pediatric, urban family medicine and rural family medicine practices, public pediatric clinics, and school-based health centers. Randomized controlled trials of reminder/recall for adolescents will be conducted at each type of site, with randomization at the level of the patient.
To explore the potential benefit of the administration of Menactra vaccine as a two-dose regimen to children. Primary Objective: To assess, by age group, the immune response to Menactra vaccine after each vaccine injection.
The purpose of this study is to determine whether a vaccine based on outer membrane vesicles (NOMV) from genetically detoxified group B meningococcus is safe and effective for use as a vaccine. If so, the NOMV in this vaccine will be combined with NOMV from two other genetically modified strains as a potentially globally effective vaccine against group B meningococcus.
The purpose of the study is to investigate whether or not GSK Biologicals' meningococcal vaccine GSK134612 is inferior to a licensed MenC-CRM197 conjugate vaccine in terms of vaccine antibody response against meningococcal serogroup C disease.
The proposed study is aimed to assess the antibody response and short-term persistence of Novartis Meningococcal B Vaccine after one, two or three doses and to evaluate the optimal vaccination schedule in an adolescent population.
In this study, subjects who were vaccinated with a meningococcal polysaccharide vaccine in a previous study (whose objectives & outcome measures are presented in a separate protocol posting with NCT number = 00227422) will be vaccinated with a new vaccine using conjugation technology. These subjects will be compared to subjects vaccinated with the new vaccine, but who were not previously vaccinated with a meningococcal polysaccharide vaccine.
The purpose of this clinical trial is to describe the safety and immunogenicity of one or two doses of Menactra® (TetraMenD) administered in children less than 2 years of age. Primary Objective: To describe the immunogenicity profile of one or two doses of Menactra® (TetraMenD) when administered to subjects aged 9, 12, 15, or 18 months in comparison to the immunogenicity of one dose of Menomune® when administered to children aged 3 years to <6 years of age.
This study is aimed at studying quadrivalent meningococcal (A, C, Y, and W-135) Tetanus Protein Conjugate Vaccine (TetraMen-T) formulations in Toddlers. Primary Objectives: Safety and Immunogenicity: To describe the safety and immunogenicity profiles of: - A single dose of each formulation of TetraMen-T vaccine - A single dose of NeisVac-C® vaccine.
