Filter by:The proposed study will evaluate the safety of the rMenB+OMV NZ in an adult population potentially at risk for meningococcal disease (e.g. lab workers). In the second part of the study additional blood samples of high responding vaccinated subjects will be collected for the purpose of generating a control serum panel for the human serum bactericidal assay (hSBA) tests.
This study compares the safety and immunogenicity profile of several travel vaccines given alone or concomitantly with MenACWY-CRM to healthy adults.
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 purpose of this trial is to describe the safety and antibody response to revaccination with Menactra vaccine in persons who received their first dose at ≥11 years of age. Primary Objective: - To evaluate the antibody responses to meningococcal serogroups A, C, Y, and W-135, measured by serum bactericidal assay using human complement (SBA-HC), induced by Menactra vaccine in subjects who were first vaccinated with Menactra 4-6 years ago. Secondary Objective: - To evaluate the antibody responses to serogroups A, C, Y, and W-135 in serum specimens collected 6 days post-vaccination in a subset of study population. Observational Objective: - To describe the rates of immediate reactions, solicited injection-site and systemic reactions, unsolicited adverse events and serious adverse events following vaccination.
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.
