Filter by:Primary objective: To check if RotaTeq® can be administered concomitantly with meningococcal Group C vaccine without impairing the efficacy of MCC vaccine. The hypothesis tested is that the seroprotection rate for MMC at 28 days after the second MCC vaccination with concomitant administration of RotaTeq® is non-inferior to that without non-concomitant (sequential) administration of RotaTeq®.
This is a modified single-blind, randomized, parallel-group, comparative, multicenter study to test Menactra vaccine in toddlers. Primary Objectives: - To evaluate the antibody responses induced by Measles, Mumps, Rubella, and Varicella (MMRV) vaccine when administered alone or concomitantly with Menactra vaccine. - To evaluate the antibody responses induced by Pneumococcal Conjugated Vaccine (PCV) when administered alone or concomitantly with Menactra vaccine. Observational Objectives: Safety - To describe the safety profile throughout the course of the study from Day 0 up to 6 months after the last study vaccination[s]) in subjects in the study groups. Immunogenicity: - To describe the antibody responses to meningococcal serogroups A, C, Y, and W-135, 30 days after the first and second Menactra vaccine administration in a subset of subjects in the first study group.
This is a Phase III, modified single-blind, randomized, parallel-group, multicenter, comparative trial in the United States designed to evaluate the immunogenicity and safety of two doses of Menactra vaccine administered alone, and concomitantly with other routine pediatric vaccines typically administered between 12 and 15 months of age. Primary Objective: To evaluate the antibody responses to meningococcal serogroups A, C, Y, and W-135. Secondary Objectives: Immunogenicity - To evaluate the antibody responses to meningococcal serogroups A, C, Y, and W-135, when Menactra vaccine is administered alone or concomitantly with Hib and MMRV vaccines. - To evaluate the antibody responses to meningococcal serogroups A, C, Y, and W-135, when Menactra vaccine is administered alone or concomitantly with PCV vaccine. Safety - To describe the safety profile within 7 and 30 days of each vaccination, and serious adverse events (SAEs) throughout the course of the study.
The purpose of this study is to evaluate the immunogenicity and safety of the concomitant administration of Menactra® vaccine and DAPTACEL® vaccine. The main objectives are: Immunogenicity: To evaluate the antibody responses to both vaccines when Menactra vaccine is given concomitantly with DAPTACEL® compared to when either vaccine is given alone. Safety: To evaluate the rate of local and systemic reactions when DAPTACEL® and Menactra vaccines are administered concomitantly compared to when each vaccine is given alone.
Immunogenicity and Safety of the Concomitant Administration of a Tdap Vaccine and Meningococcal ACWY Conjugate Vaccine in Healthy Subjects Aged 11-25 Years
Infant phase: To determine the safety of and production of antibodies by a group C meningococcal conjugate vaccine (MnCC), when given at 2, 3, and 4 months of age with routine vaccines. Booster phase: To compare the safety of and production of antibodies by MnCC with and without MMR and to compare the antibody response to that produced by a low dose of plain polysaccharide vaccine as a way of investigating immune memory
To assess the immunogenicity of Novartis (formerly Chiron) Meningococcal ACWY conjugate vaccine (MenACWY) when administered as a two-dose schedule at 6 and 12 months of age.
To compare the functional immune response 28 days after administration of one dose of Men ACWY-CRM conjugate vaccine without adjuvant (MenACWY-CRM(Ad-)) with that of a Men ACWY polysaccharide (PS) vaccine
To determine the safety & immunogenicity of a potential vaccine against meningococcal B disease
Hypothesis: Lower doses of each A/C/Y/W135 component of the meningococcal polysaccharide vaccine could confer a similar functional immunogenic response as the dose of 50 μg currently being used, and subsequently be equally protective. The purpose of this study is to evaluate the use of fractional dose tetravalent meningococcal polysaccharide vaccine to control outbreak especially caused by N. meningitidis serogroup W135 Primary Objectives: - To measure the immunogenicity of a dose corresponding to one fifth of the amount of the licensed meningococcal A/C/Y/W135 polysaccharide vaccine, i.e. 10 μg for each component; and - To measure the immunogenicity of a dose corresponding to one tenth of the licensed meningococcal A/C/Y/W135 polysaccharide vaccine, i.e. 5 μg for each component.
