Filter by: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.
The purpose of this study is to determine if the vaccine called Group B Meningococcal 44/76 MOS NOMV 5D Vaccine is safe and free from side effects and if it will protect people from meningitis. This study will vaccinate three groups of people. In the first 2 groups, the study will be double-blinded. This means that neither the volunteer or the medical team will know which formulation of the vaccine was administered. The third group of volunteers and the medical team will know that they are receiving the higher dose of the vaccine.
The primary aim of the study is to show that NeisVac-C does not influence the seroconversion rates induced by hepatitis B (Hep B), inactivated polio (IPV) and acellular pertussis (aP) vaccines in infants.
