Active clinical trials for "Diphtheria"

The purpose of this study is to assess the immunogenicity and safety of GSK Biologicals' Infanrix hexa vaccine when administered to healthy infants as primary vaccination at 2, 4 and 6 months of age, co-administered with Prevnar and Rotarix with a booster dose of GSK Biologicals' Infanrix and Hiberix vaccines at 15-18 months of age.

The purpose of this follow-up study is to evaluate the persistence of antibodies against all the vaccine antigens 10 years after booster vaccination with either Tdap or Td, and also to assess immunogenicity and safety of another dose of Boostrix, administered in this study. This protocol posting deals with objectives and outcome measures of the extension phase. The objectives and outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00109330).

In the UK, infants currently receive a 5-in-1 vaccine (Pediacel) at 2, 3 and 4 months of age, which protects against diphtheria, tetanus, pertussis (whooping cough), polio and Haemophilus influenzae type b (Hib). Infants also routinely receive a meningococcal group C vaccine (MenC) at 3 and 4 months and a 13-valent pneumococcal vaccine (Prevenar13) at 2 and 4 months of age. This study aims to offer infants a 6-in-1 vaccine (Infanrix-Hexa)that also helps protect against hepatitis B alongside the other routine vaccinations in the UK infant immunisation schedule and assess their immune responses to the different vaccines. Hepatitis B virus infects the liver and usually affects adults, but children can be infected through close contact with carriers of the virus. Children with hepatitis B infection may not have symptoms for many years but may go on to develop liver failure, cirrhosis and cancer. Many other countries already use Infanrix-Hexa and this study is being undertaken to help decide whether the UK can do the same. Babies taking part in this study will receive Infanrix-Hexa instead of Pediacel. All other vaccines given will be the same as in the routine schedule but will include one MenC vaccine instead of 2 doses because the UK infant immunisation schedule is soon going to change so that all babies will receive only one MenC vaccine at 3 months of age. There are currently several licensed MenC vaccines that can be given to babies. In order to check whether there are differences in protection, babies taking part will randomly receive one of 3 MenC-containing vaccines: NeisVacC, Menjugate or Menitorix. Studies have already shown that one dose of Neis-Vac or Menjugate given to babies at 3 months provides similar protection against MenC infection as two doses given at 3 and 4 months. Menitorix protects against both Hib and MenC, so babies in the group receiving MenitorixTM will have an extra dose of Hib which is also included in Infanrix-Hexa but might have a lower antibody response to MenC compared to the other two MenC vaccines, although all infants should be well-protected after their 12-month booster vaccinations, which also contain Menitorix.

The aim of the study is to assess the safety profile of ADACEL vaccine in a small number of participants in China. Primary objective: To describe the safety in terms of occurrence of serious adverse reactions and grade 3 adverse reactions after administration of Sanofi Pasteur's Tdap vaccine (ADACEL) given as a single dose in 20 adults and 20 children. Secondary objective: To describe the full reactogenicity profile after administration of sanofi pasteur's Tdap vaccine (ADACEL) given as a single dose in 20 adults and 20 children.

Primary objective: To demonstrate the non-inferiority in terms of seroprotection rates (Hib antigen (PRP), Diphtheria, Tetanus, and Pertussis antigens (PT and FHA), and polio types 1, 2 and 3 antigens) of investigational arm (Group A: DTaP-IPV/Hib) versus control arm (Group B: DTaP-IPV and Hib vaccines administered at separate sites), one month after the primary vaccination (all antigens). Secondary objectives: To describe immune responses against all vaccine antigens with no pre-specified hypothesis, and at all time points (pre-dose 1, post-dose 3, pre-dose 4 and post-dose 4) in the two study groups (Group A and Group B). To describe the safety after each dose of each vaccine in the two study groups (Group A and Group B). To describe immune responses against all vaccine antigens with no pre-specified hypothesis, and at all time points (pre-dose 1, post-dose 3, pre-dose 4 and post-dose 4 (Group C)

The current trial will evaluate the safety and immunogenicity of GSK Biologicals' GSK2202083A vaccine when administered as a booster dose following priming in the first year of life with the same 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 = NCT00970307).

This study is designed to assess the immunogenicity and safety of PENTAXIM™ combined vaccine versus TETRAXIM™ vaccine to support registration of PENTAXIM™ in South Korea. Primary Objective: To demonstrate the non-inferiority in terms of seroprotection rates (Diphtheria, Tetanus, Polio types 1, 2 and 3, Polyribosyl Ribitol Phosphate [PRP]) and vaccine response rates to acellular Pertussis antigens of sanofi pasteur's PENTAXIM™ vaccine versus sanofi pasteur's TETRAXIM™ and Act (Haemophilus influenzae type b) HIB™ vaccines, one month after the three-dose primary vaccination.

The study will compare the immunogenicity and the reactogenicity of INFANRIX™ HEXA and HEXAVAC™ vaccines in a 3, 5 and 11 - 12 month vaccination schedule.

This study is designed to assess the safety and immunogenicity of a single dose of Meningococcal (Groups A, C, Y and W-135) Polysaccharide Diphtheria Toxoid Conjugate Vaccine (SP284) to support registration of the product in Japan. Primary Objective: To describe the seroprotection rate [% of subjects with serum bactericidal assay using baby rabbit complement (SBA-BR) ≥1:128] to meningococcal antigens (serogroups A, C, Y and W-135) following vaccination with SP284 vaccine in subjects 2 through 55 years of age Secondary Objectives: To describe the safety following receipt of SP284 vaccine in subjects 2 through 55 years of age To describe the immune responses to meningococcal antigens (serogroups A, C, Y and W-135) following vaccination with SP284 vaccine in subjects 2 through 55 years of age.

The purpose of this study is to assess the immunogenicity, safety and reactogenicity of the booster vaccine dose of 2 new formulations of DTPa-HBV-IPV/Hib administered between 12 and 15 months of age, and the immune persistence following the primary series. All children in this booster study received a primary vaccination at 2, 3 and 4 months of age in study 113948 (NCT01248884). No new subjects will be enrolled in this booster study.
