Active clinical trials for "Diphtheria"

The purpose of this study is to describe the safety and immunogenicity of repeat administration of Adacel vaccine approximately 10 years following initial administration of the vaccine. Antibody levels prior to revaccination will also be used to characterize antibody persistence following initial vaccination 10 years earlier. Primary Objectives: To compare seroprotection rates against tetanus and diphtheria induced by Adacel vaccine to those induced by Td Adsorbed vaccine. To compare booster response rates against tetanus and diphtheria induced by Adacel vaccine to those induced by Td Adsorbed vaccine. To compare anti-pertussis geometric mean antibody concentrations (GMCs) induced by Adacel vaccine to the GMCs induced by Daptacel® vaccine given to infants. Secondary Objectives: To describe the rates of immediate reactions, solicited reactions, unsolicited adverse events (AEs), and serious adverse events (SAEs) following vaccination with Adacel or Td Adsorbed vaccine. To describe booster response rates for pertussis antigens following revaccination with Adacel vaccine.

This study is designed to evaluate the safety and immunogenicity of new formulations of GSK Biologicals' DTPa-HBV-IPV/Hib vaccine (GSK217744) when administered as a primary vaccination course to healthy infants at 2, 3 and 4 months of age.

Primary objectives: To demonstrate that REPEVAX and VAXIGRIP administered concomitantly in subjects 60 years of age and older are at least as immunogenic as REPEVAX or VAXIGRIP administered separately. Secondary objectives: •Secondary immunogenicity objectives: To describe the immune responses 28 days after concomitant or separate administration of REPEVAX and VAXIGRIP in subjects 60 years of age and older To describe the immune response of VAXIGRIP according to European Medicines Agency criteria in subjects 60 years of age and older (Note for Guidance, 1997: 28) •Secondary safety objective: To describe the safety profile after vaccination in each group

This study will evaluate immunogenicity, safety and tolerability of fully liquid pentavalent vaccine (DTwP-Hib-HepB Vaccine) in infants 6-8 weeks of age.

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.

Booster and immune memory study

The purpose of this study is to assess the safety in terms of fever (rectal temperature) higher than 39 degree Celcius (°C) and the immunogenicity in terms of antibody response following a booster vaccination with pneumococcal vaccine GSK1024850A at 11 to 18 months of age in children previously primed with the same vaccines including a pneumococcal conjugate vaccine co-administered with a diphtheria, tetanus, acellular pertussis (DTPa)-combined and meningococcal serogroup C (MenC) or combined meningococcal serogroup C and Haemophilus influenzae type b (Hib-MenC) vaccine. 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 = NCT00334334).

This study will only include infants born to mothers who are tested as seronegative for human immunodeficiency virus (HIV) & hepatitis B surface antigen (HBsAg). The purpose of this study is to demonstrate in infants who received a birth dose of hepatitis B vaccine that Tritanrix™-HepB/Hib-MenAC vaccine is at least as good as Tritanrix™-HepB/Hiberix™ with respect to immunogenicity of the hepatitis B antigen.

The present clinical study will assess the immunogenicity and reactogenicity of Sanofi Pasteur's DTaP-IPV combined vaccines as a three-dose primary vaccination at 2, 4 and 6 months of age compared to commercially available vaccines in order to meet the requirements for registration of the product in South Korea. Primary objective To demonstrate the non-inferiority in terms of seroprotection rates (Diphtheria, Tetanus, Polio types 1, 2 and 3) and seroconversion/vaccine response rates to Pertussis antigens (PT, FHA) of Sanofi Pasteur's DTaP-IPV combined vaccine versus commercially available Biken's DTaP (CJ purified PDT vaccine ™) and Aventis Pasteur's IPV (IMOVAX POLIO) monovalent vaccines, one month after the three-dose primary vaccination. Secondary objectives Immunogenicity: To assess the non-inferiority in terms of seroprotection rates (Diphtheria, Tetanus, Polio types 1, 2 and 3) and seroconversion / vaccine response rates to Pertussis antigens (PT, FHA) of Sanofi Pasteur's DTaP-IPV combined vaccine versus historical reference (Study E2I03294 - France). To assess and describe the immunogenicity of the study vaccines in both groups. Safety: To assess and describe the safety of the study vaccines after each dose.

This is a study to compare the safety and immune response of a pentavalent DTaP-HB-PRP~T combined vaccine with Tritanrix-HepB/Hib™, when both are given concomitantly with OPV at 6, 10, and 14 weeks of age.
