Filter by: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
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.
To explore the potential benefit of the administration of Menactra vaccine as a two-dose regimen to children. Primary Objective: To assess, by age group, the immune response to Menactra vaccine after each vaccine injection.
The purpose of this clinical trial is to describe the safety and immunogenicity of one or two doses of Menactra® (TetraMenD) administered in children less than 2 years of age. Primary Objective: To describe the immunogenicity profile of one or two doses of Menactra® (TetraMenD) when administered to subjects aged 9, 12, 15, or 18 months in comparison to the immunogenicity of one dose of Menomune® when administered to children aged 3 years to <6 years of age.
This study is aimed at studying quadrivalent meningococcal (A, C, Y, and W-135) Tetanus Protein Conjugate Vaccine (TetraMen-T) formulations in Toddlers. Primary Objectives: Safety and Immunogenicity: To describe the safety and immunogenicity profiles of: - A single dose of each formulation of TetraMen-T vaccine - A single dose of NeisVac-C® vaccine.
The purpose of the study is to evaluate the immune response of toddlers, to a booster dose in the second year of life of two meningococcal C conjugated polysaccharide vaccine, and to assess the interchangeability of the two different vaccines.
This study is evaluating antibody persistence at 1, 3 & 5 years post-fourth dose (i.e., at 2, 4 & 6 years of age, respectively) in subjects vaccinated in a previous study. This protocol posting deals with objectives & outcome measures of the extension phase at years 1, 3 and 5. The objectives & outcome measures of the first four doses are presented in a separate protocol posting (NCT00129129). This protocol posting has been amended in order to comply with the FDA Amendment Act of September 26, 2007.
The booster phase of the study will evaluate the safety of Hib-MenCY-TT vaccine compared to a control group receiving licensed Hib conjugate vaccine at 12 to 15 months of age. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00345579). No new recruitment will take place during this booster phase of the study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
Safety, Tolerability and Immunogenicity of Meningococcal C Conjugate Vaccine to Children 32 to 40 Months of Age
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.
