Filter by:This study compares the safety and immunogenicity profile of combined hepatitis A/B vaccine given alone or concomitantly with MenACWY-CRM to healthy adults.
The purpose of this US FDA post-marketing commitment study is to evaluate the safety of MenACWY-CRM among 50.000 vaccinated adolescents within a large US Healthcare Maintenance Organization who received MenACWY-CRM vaccination as part of their routine clinical care. The pre-specified 26 events of interest are events commonly evaluated in vaccine safety studies and include certain neurological, immunological, vascular, musculoskeletal and hematologic disorders. All events are collected retrospectively.
The purpose of this study is to summarize the occurrence of incident serious medically attended events and events of interest up to 1 year following MenACWY-CRM vaccination administered as part of routine clinical care. This US FDA post-marketing commitment study is an open-label, descriptive, epidemiological safety surveillance study of MenACWY-CRM vaccine in subjects 2 to 10 years of age within a large US Healthcare Maintenance Organization. The 26 events of interest are events commonly evaluated in vaccine safety studies and include certain neurological, immunological, vascular, musculoskeletal and hematologic disorders. All events are collected retrospectively.
The study was to evaluate the safety and and immune response of each of three lots of Novartis Meningococcal C Conjugate Vaccine (MenC-CRM Liquid) when administered to Healthy Toddlers.
This study is part of the post-licensure commitment to evaluate the safety and immunogenicity of Meningo A+C vaccine in healthy Chinese children 2 to 6 years of age. Primary Objective: To demonstrate the non-inferiority in terms of seroconversion rate for serogroups A and C, 30 days after a single dose of Sanofi Pasteur Meningococcal (Groups A and C) Polysaccharide Vaccine versus Lanzhou Institute for Biological Products Meningococcal (Groups A and C) Polysaccharide Vaccine. Secondary Objective: - To describe the immunogenicity for serogroups A and C, 30 days after administration of the study vaccines given as a single dose. - To describe the full reactogenicity profile after administration of the study vaccines given as a single dose.
The primary objective of this study is to demonstrate the equivalence of rMenB+OMV NZ lot 1 to rMenB+OMV NZ lot 2 when administered to adolescents, as measured by human serum bactericidal activity (hSBA) geometric mean titers (GMTs) against 3 N. meningitidis serogroup B reference strains (H44/76, 5/99, and NZ98/254) and as measured by ELISA geometric mean concentrations (GMCs) against vaccine antigen 287-953, approximately 30 days after a primary vaccination course of two doses administered one month apart.
This study will evaluate safety, tolerability, and immunogenicity of a booster dose of a meningococcal vaccine formulation in adolescents.
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.
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.
Major epidemics of meningococcal meningitis occur in countries of the African Sahel and sub-Sahel every few years. Most of these epidemics are caused by meningococci belonging to serogroup A. Until recently there has been no serogroup A conjugate vaccine available to prevent epidemics in Africa because none of the major pharmaceutical companies wanted to develop such a vaccine for commercial reasons. For this reason a public private partnership was established in 2001, the Meningitis Vaccine Project (MVP), with support from the Bill and Melinda Gates Foundation, to develop an affordable new serogroup A meningococcal conjugate vaccine for Africa. The new vaccine, MenAfriVac™, received WHO pre-qualification in 2010 and mass campaigns started in Burkina Faso, Mali and Niger in 2010. It is expected that full coverage through mass vaccination campaigns will be achieved by the end of 2011 in these three countries. A case-control study will be conducted in Mali and Niger during the epidemic seasons of 2012 and 2013 to assess the efficacy of MenAfriVac™.
