Filter by:Immunogenicity and Safety of the Concomitant Administration of a Tdap Vaccine and Meningococcal ACWY Conjugate Vaccine in Healthy Subjects Aged 11-25 Years
Data from this study are expected to demonstrate that V501 (Human Papillomavirus (HPV) [Types 6, 11, 16, 18] Recombinant Vaccine) , when administered concomitantly with a combined diphtheria, tetanus, pertussis (Tdap) vaccine and a meningococcal conjugate vaccine in adolescents remains immunogenic and well-tolerated and it does not impair the immunogenicity of the concomitant vaccines.
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
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 study is designed to evaluate the persistence of bactericidal antibodies in subjects aged 15 to 23 years (not yet 24 years) who had been vaccinated five years previously in Study MTA02 and did not participate in Study MTA19 (NCT 00777790). In addition, the kinetics of the antibody response will be evaluated in a subset of these participants who will receive a booster dose of Menactra® vaccine. This will be compared to aged matched control subjects who have not been previously vaccinated with a meningococcal vaccine or had documented meningitis disease who will also receive a dose of Menactra® vaccine.
The study is designed to evaluate the persistence of bactericidal antibodies in subjects aged 7 to 15 years (not yet 16 years) who had been vaccinated five years previously in Study 603-02. In addition, the kinetics of the antibody response will be evaluated in a subset of participants who will receive a booster dose of Menactra® vaccine and children in the same age group not previously vaccinated with a meningococcal vaccine or had meningitis disease who will receive a dose of Menactra® vaccine.
To further characterize the safety profile of Menactra vaccine and to identify any signals of potentially vaccine-related adverse events (AEs) not detected during pre-licensure studies.
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 aim of this study is to determine the prevalence of pneumococcal meningitis in the paediatric population in Spain four years after the marketing of Prevenar. Also secondary objectives are: 1) to determine the clinical characteristics and outcome of the disease; and 2) to determine serotypes and antibiotic resistance patterns.
