Filter by: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 purpose of this study is to evaluate the safety and immunogenicity of Novartis Meningococcal ACWY Conjugate Vaccine in comparison to licensed meningococcal polysaccharide vaccine administered to healthy adolescents ages 11 to 17 years.
The purpose of this study is to evaluate the safety and immunogenicity of Novartis (formerly Chiron) Meningococcal ACWY Conjugate Vaccine administered to healthy children ages 1 - 10 years
The purpose of this study is to evaluate the safety, immunogenicity and induction of immune memory after two or three doses of Novartis (Formerly Chiron) Meningococcal ACWY Conjugate Vaccine administered to healthy infants.
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 evaluate that the vaccine produced with the new process and administered as a single dose is at least as good as the existing Mencevax™ ACWY vaccine in terms of immunogenicity, safety and reactogenicity, in healthy subjects aged 2-30 years.
The purpose of the study is to evaluate the immune responses of UK infants after one or two doses of pneumococcal conjugate vaccine or one or two doses of three different types of meningococcal conjugate vaccine given at either two and three or two and four months of age.
The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of one dose of four different formulations of the MenACWY conjugate vaccine when given to healthy children aged 12-14 months and 3-5 years. The selection of the best formulation will be based on data obtained up to one month after the vaccine dose. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of this study is to evaluate the immunogenicity, safety and reactogenicity of one dose of four different formulations of the MenACWY conjugate vaccine when given to healthy subjects aged 15-19 years. The selection of the best formulation will be based on data obtained up to one month after the vaccine dose.
