Filter by:The purpose for this study is to demonstrate the safety and immunogenicity of two doses of Menactra® administered between 12 and 18 months of age and concomitantly with routine immunization with two different provincial schedule Primary Objectives: - To describe the immunogenicity of Menactra® administered concomitantly with routine immunizations at 12 and 18 months in naïve or Menjugate-primed (MenC-primed) infants (measured by serum bactericidal assay using baby rabbit complement [SBA-BR]) - To describe the immunogenicity of MenC administered concomitantly with routine immunizations at 12 months of age (measured by SBA-BR) Secondary Objectives: Safety - To describe the safety profile of Menactra® and MenC vaccines after each dose when given concomitantly with routine immunization. Immunogenicity - To describe the immunogenicity of both vaccines using serum bactericidal assay using human complement [SBA-HC] - To describe the immunogenicity of Pediacel administered at 18 months.
The primary purpose of this study is to evaluate the persistence of bactericidal antibodies in children of approximately 22 to 45 months of age previously enrolled in the V59P22 study (NCT00667602) who received Novartis MenACWY Conjugate Vaccine or Meningococcal C Conjugate Vaccine. This is measured by percentage of subjects with human Serum Bactericidal Assay (hSBA) titers ≥ 1:8 directed against Neisseria meningitidis serogroups A, C, W-135, and Y. In addition the response one month post an additional dose of Novartis MenACWY will be measured by percentage of subjects with hSBA titers ≥ 1:8 and GMTs.
This study evaluates the immunogenicity and safety of the meningococcal conjugate vaccine GSK 134612 in healthy infants, when co-administered with other infant vaccines, on three different dose schedules.
The proposed study is aimed at assessing the safety and immunogenicity of rMenB+OMV NZ when administered alone without routine infant vaccines to healthy infants in their first year of life according to different two and three dose immunization schedules, which are suitable to be adopted by various national programs. This study will also investigate antibody persistence post primary series and administration of a subsequent booster dose of rMenB+OMV NZ at 11 months of age. In addition, this study will assess the safety and immunogenicity of two catch-up doses of rMenB+OMV NZ when administered to healthy children 2 to 10 years of age. This study will also evaluate the safety and immunogenicity of the concomitant administration of rMenB+OMV NZ with meningococcal C conjugate vaccine (MenC-CRM) according to a 3, 5 and 12-month schedule.
This study is designed to evaluate the immunogenicity and the safety of a quadrivalent vaccine MenACWY-CRM in healthy subjects from 11 to 55 years of age in Korea.
This study will evaluate the safety and immunogenicity of combination vaccines as compared to the reference vaccines
This aim of the study is to assess post-marketing safety of a single dose of Menactra® vaccine with the intent to support conversion from monitored release to initial registration of Menactra® vaccine in the Philippines. Primary Objective: To describe the serious adverse events occurring within 30 days among participants who have received one dose of Menactra® vaccine.
The purpose of the study is to evaluate the persistence of the immune response of GSK134612 vaccine up to 68 months after vaccination in the primary vaccination study (NCT number = NCT00674583) of 2 to 10 year old subjects. This study will also evaluate the safety and immunogenicity of a booster dose of GSK134612 vaccine subjects who were primed in the primary vaccination study with either GSK134612 vaccine or Menjugate®. This protocol posting deals with objectives & outcome measures of the persistence and booster epochs. The objectives & outcome measures of the primary epoch are presented in a separate protocol posting (NCT number = NCT00674583)
The purpose of this trial is to describe antibody persistence and response to re-vaccination with either Menactra® or Menomune® vaccine approximately three years following initial vaccination in adults who participated in trial MTA29 (NCT00874549). Objectives: - To describe the rates of immediate reactions, solicited injection-site and systemic reactions, all unsolicited adverse events, and serious adverse events following vaccination. - To evaluate persistence of serum bactericidal antibodies in subjects who received Menactra® or Menomune® vaccine approximately three years ago. - To evaluate the immune response to serogroups A, C, Y, and W-135 in subjects re-vaccinated with either Menactra® or Menomune® vaccine.
This study evaluates the immunogenicity and safety of the meningococcal conjugate vaccine GSK 134612 given as single dose to healthy adults 56 years or older compared to the meningococcal polysaccharide vaccine MencevaxACWYTM.
