Active clinical trials for "Meningococcal Infections"

The purpose of this study is to assess the safety and reactogenicity of a booster dose of diphtheria-tetanus-whole cell pertussis-hepatitis B virus/Haemophilus influenzae type b vaccine (DTPw-HBV/Hib) at 15-18 m and to assess the immunogenicity, safety, and reactogenicity of a dose of Mencevax™ Group A, C and W135 polysaccharide meningococcal vaccine (ACW) at 24 to 30 m in primed subjects. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

Immunogenicity and Safety of the Concomitant Administration of a Tdap Vaccine and Meningococcal ACWY Conjugate Vaccine in Healthy Subjects Aged 11-25 Years

The purpose of this study was to evaluate the optimal vaccination schedule for a Quadrivalent Meningococcal Polysaccharide (A, C, Y and W-135) Tetanus Protein Conjugate Vaccine (MenACYW Conjugate vaccine) in order to provide an effective protein conjugate quadrivalent meningococcal vaccine in the population with the highest incidence of disease. Objectives: To describe the safety profile of MenACYW Conjugate vaccine administered at 5 different schedules and concomitantly with routine pediatric vaccinations. To describe the immunogenicity profile of MenACYW Conjugate vaccine administered at 5 different schedules and concomitantly with routine pediatric vaccinations. To describe the immunogenicity profiles of selected licensed pediatric vaccines (Pentacel, Prevnar, M-M-RII, and Varivax) when administered either concomitantly with or without MenACYW Conjugate vaccine.

This study is to confirm non-inferiority of the three MenACWY vaccines (Menveo, Menactra or Nimenrix) in adolescents, and to identify whether the number of previous doses of MenC influences the response to the MenACWY vaccine.

The purpose of the study was to assess the immunogenicity and safety of two doses of Novartis Meningococcal B Recombinant (rMenB+OMV NZ) vaccine administered one month apart (0, 1 month schedule) in Korean adolescents aged between 11 to 17 years.

The purpose of this study is to evaluate the production of antibodies to a new conjugate vaccine, NmVac4-A/C/Y/W-135-DT, as a measure of vaccine effectiveness, compared to the production of antibodies to a similar, licensed meningococcal (Groups A, C, Y, W-135) polysaccharide diphtheria toxoid (DT) conjugate vaccine. The investigators will also evaluate the safety of NmVac4-A/C/Y/W-135-DT™ conjugate vaccine compared to the licensed vaccine. The hypothesis is that the test vaccine is comparable to the licensed active control vaccine.

The purpose of this study is to compare the immediate and long term (up to 5 years) immunogenicity and safety of GSK Biologicals' MenACWY-TT vaccine when given as a single dose or as 2 doses to toddlers aged 12 to 14 months. Also, this study will also assess if co-administration of GSK Biologicals' MenACWY-TT with the booster dose of Pfizer's Prevenar 13 adversely impacts the immunogenicity of either of the vaccines.

Evaluate the immune response and reactogenicity of one dose of Meningococcal ACWY-cross reactive material (CRM) and Meningococcal ACWY-tetanus toxoid (TT) in 12-15 months old healthy toddlers.

The purpose of this study is to investigate the immunogenicity, reactogenicity and safety of the new meningococcal vaccine 134612 in subjects with increased risk of meningococcal disease and compare it to its activity in healthy subjects.

The aim of the study is to further characterize the safety and immunogenicity of Menactra® in the population <2 years of age when administered alone and when the second dose is administered concomitantly with the 4th dose of Pentacel®, a licensed pediatric vaccine. Primary Objectives: To evaluate and compare the antibody responses to meningococcal serogroups A, C, Y, and W-135 induced by 2 injections of Menactra® in subjects aged 9 months at the first vaccination visit and 15 to 18 months at the second vaccination visit. To evaluate and compare the antibody responses to Pertussis (pertussis toxoid [PT], filamentous haemagglutinin [FHA] and pertactin [PRN]) antigens induced by a dose of Pentacel® when administered concomitantly with Menactra® to those elicited by a dose of Pentacel® administered alone. To evaluate and compare the antibody responses to polyribosylribitol phosphate (PRP), tetanus and diphtheria antigens induced by a dose of Pentacel® when administered concomitantly with Menactra® to those elicited by a dose of Pentacel® alone. Observational Objectives: To describe the safety profile (immediate unsolicited AEs within 30 minutes of each trial vaccination, solicited reactions within 7 days of each vaccination, unsolicited AEs within 30 days of each vaccination, and serious adverse events [SAEs] throughout the course of the trial from Day 0 up to Day 30 after the last trial vaccination[s]) in all trial groups To describe the antibody responses to meningococcal serogroups A, C, Y, and W-135, measured by SBA HC, 30 days after the second Menactra® administration To describe the antibody responses to Pentacel® (PT, FHA, PRN, FIM, diphtheria, tetanus, polio, PRP) measured by enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), or functional assays.
