Active clinical trials for "Meningococcal Infections"

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.

The purpose of the observer-blinded study is to determine the immunogenicity and safety of one dose of GlaxoSmithKline (GSK) Biologicals' meningococcal vaccine GSK 134612 compared to one dose of Mencevax™ ACWY in healthy subjects 18-25 years of age. In addition, this study will compare the immunogenicity of two lots of GSK's 134612 vaccine.

The objective of this trial is to study the administration of the Menomune vaccine given intradermally and low-dose subcutaneously versus standard subcutaneously. This study will describe the immunogenicity of Menomune® - A/C/Y/W-135 administered subcutaneously (standard dose) versus intradermally over a dose range (1/10th, 2/10th, and 3/10th of standard dose) and a low dose (2/10th of standard dose) subcutaneously. The secondary objective is to describe the safety of the subcutaneous (SC) and intradermal (ID) routes at different dosages

The primary objective of this phase 3b study is to evaluate the safety and tolerability of Novartis MenACWY conjugate vaccine when administered with routine infant vaccinations to healthy infants

To evaluate the safety and immune response of Novartis MenACWY conjugate vaccine when given to healthy children compared to a licensed Meningococcal ACWY polysaccharide-protein conjugate vaccine.

In this study, subjects who were vaccinated with a meningococcal polysaccharide vaccine in a previous study (whose objectives & outcome measures are presented in a separate protocol posting with NCT number = 00227422) will be vaccinated with a new vaccine using conjugation technology. These subjects will be compared to subjects vaccinated with the new vaccine, but who were not previously vaccinated with a meningococcal polysaccharide vaccine.

A study team with extensive experience in immunization delivery research will evaluate the effectiveness of vaccination reminder/recall systems for adolescent patients in five types of clinical settings including: urban pediatric, urban family medicine and rural family medicine practices, public pediatric clinics, and school-based health centers. Randomized controlled trials of reminder/recall for adolescents will be conducted at each type of site, with randomization at the level of the patient.

The purpose of the study is to characterize the safety and immunogenicity of 1 dose of GSK Biologicals' meningococcal vaccine GSK134612 as compared to Menactra® in adolescents/adults 11-25 years of age. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007. The protocol posting has been updated following a protocol amendment.

The purpose of this study is to demonstrate, in 12-23 month old children, the non-inferiority of the meningococcal vaccine 134612 given with Priorix-Tetra. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

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.
