Filter by:The aim of this extension study is to explore the antibody persistence 24 to 36 months after the last dose of vaccine, in infants that received a two or three dose primary series plus a booster dose at 11 months of age, of the Novartis meningococcal B vaccine (Bexsero®) in groups I to III of the parent V72_28 study. This study will also explore the antibody persistence 24 to 36 months after two catch-up doses of the Novartis meningococcal B vaccine (Bexsero®) administered in children (2 to 10 years old) in group IV of the parent V72_28 study.
Primary objectives: - To describe the antibody responses to meningococcal serogroups A, C, Y, and W 135, measured by serum bactericidal assay using human complement (hSBA) and baby rabbit complement (rSBA), induced by a single dose of Meningococcal Polysaccharide (A, C, Y, and W 135) Tetanus Protein (MenACYW) Conjugate vaccine or Menomune® - A/C/Y/W 135. - To describe the safety profile of a single dose of MenACYW Conjugate vaccine or Menomune® - A/C/Y/W 135.
It is a Phase 3 extension of study V72P12E1 (NCT00944034). The main aim of the second extension study is to explore the bactericidal antibody persistence in 4-year-old children after a fourth dose boost of rMenB+OMV NZ or after a two-dose catch-up schedule of rMenB+OMV NZ administered to toddlers as part of their respective vaccination courses in study V72P12E1. In addition, this study will characterize the antibody response to a fifth dose boost in all children who received a three-dose primary series of rMenB+OMV NZ at 2, 3, 4 months of age (in parent study V72P12, NCT00721396), and only in a subset of children who received a three-dose primary series of rMenB+OMV NZ at 2, 4, 6 months of age (in parent study V72P12). Antibody response will also be characterized to a third dose boost of rMenB+OMV NZ administered at approximately 4 years of age in all children who received a two catch-up doses of rMenB+OMV NZ as toddlers in study V72P12E1. Finally, the safety and immunogenicity of two catch-up doses of rMenB+OMV NZ administered 2 months apart to healthy naïve children at 4 years of age will be assessed.
This study is designed to assess the safety and immunogenicity of a single dose of Meningococcal (Groups A, C, Y and W-135) Polysaccharide Diphtheria Toxoid Conjugate Vaccine (SP284) to support registration of the product in Japan. Primary Objective: - To describe the seroprotection rate [% of subjects with serum bactericidal assay using baby rabbit complement (SBA-BR) ≥1:128] to meningococcal antigens (serogroups A, C, Y and W-135) following vaccination with SP284 vaccine in subjects 2 through 55 years of age Secondary Objectives: - To describe the safety following receipt of SP284 vaccine in subjects 2 through 55 years of age - To describe the immune responses to meningococcal antigens (serogroups A, C, Y and W-135) following vaccination with SP284 vaccine in subjects 2 through 55 years of age.
The purpose of this study is to evaluate the safety of a new conjugate vaccine, NmVac4-A/C/Y/W-135-DT, compared to the safety of a similar, licensed meningococcal A/C/Y/W-135-DT conjugate vaccine. The investigators will also evaluate the production of antibodies to of NmVac4-A/C/Y/W-135-DT™ conjugate vaccine compared to the licensed vaccine, as a measure of vaccine effectiveness.
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 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.
The main objective is to determine whether immune responses to Tdap (GlaxoSmithKline, Boostrix®) and HPV vaccine (Merck & Co., Inc., Gardasil®) when administered concomitantly with MenACWY are comparable to responses elicited by these vaccines when given alone.
