Active clinical trials for "Diphtheria"

The purpose of this study is to assess the efficacy and safety of repeating dTpa booster in adults 10 years after previous booster vaccination with dTpa in a previous clinical study (NCT01267058). Only subjects who received the booster vaccination in a previous clinical study are eligible for participation in this study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007. No new recruitment will be performed in this booster phase (see inclusion criteria).

This is a follow-up of Study A3L10 (NCT00315055) Immunogenicity To describe the antibody persistence following a primary series vaccination of either DTaP-IPV-HB-PRP~T or PENTAXIM™ and ENGERIX B®. To describe the immunogenicity of a booster dose of DTaP-IPV-HB-PRP~T. Safety - To describe the safety profile after a booster dose of DTaP-IPV-HB-PRP~T.

An open clinical trial to study the immune response and safety after giving a booster dose (5th Dose) of a combination vaccine against Diphteria-Tetanus-Pertussis-Polio to healthy adolescents 15-16 Years of age. The first three doses were given during the first year of life, according to the Norwegian child immunization program. The fourth dose was given in a previous clinical trial performed in 1998 when the children were 6-7 years old. In 2006 there was a change in the child immunization program in Norway: a fourth dose of a Combination Vaccine Against Diphteria-Tetanus-Pertussis-Polio is given to children 6-7 years old. This study will give us information if there is need for an additional dose (5th dose) of a combination vaccine, containing the pertussis components, before the adolescents are leaving secondary school.

The purpose of this study is to document the immunological response to the investigational hexavalent vaccine at the 6, 10, and 14 weeks schedule The primary objective is to demonstrate that the hexavalent DTaP-IPV-HB-PRP~T combined vaccine does not induce lower immune responses than CombAct-HIB® with Engerix B® Paediatric and OPV in terms of seroprotection rates to Diphtheria (D), Tetanus (T), polio, Hepatitis B (HB), and Polyribosyl ribitol phosphate (PRP), one month after a 3-dose primary series (6, 10, and 14 weeks) with no HB vaccination at birth. The secondary Objectives are: To describe the safety in terms of any adverse events in the first 28 days after each injection and any serious adverse events during the entire trial. To describe Immunogenicity after the primary series and prior to and after a booster vaccination.

PR5I, a hexavalent pediatric combination vaccine is being developed to reduce the number of injections during the first 2 years of life while providing a complete course of immunization against infection caused by H. influenzae type b, hepatitis B virus, Corynebacterium diphtheriae, Clostridium tetani, Bordetella pertussis, and poliovirus types 1, 2, and 3. Primary Objective: To evaluate immunogenicity of PR5I with the adjuvant composition enhancement to the hepatitis B component when administered concomitantly with Prevnar® Secondary Objectives: To assess the safety and immunogenicity of PR5I when administered concomitantly, or one month apart with Prevnar® or separately with licensed vaccines used for routine infant vaccination in Canada.

To assess the safety and reactogenicity of the DTPa-IPV/Hib vaccine as primary and booster vaccination. The DTPa-IPV/Hib vaccine given at 3 and 4 months of age is co-administered with GSK Biologicals' rotavirus vaccine or Placebo. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

To assess the anti-PRP antibody response one month after vaccination in the groups receiving a fourth consecutive dose of two formulations of DTPw-HBV/Hib vaccine

To assess the immunogenicity profile of ADACEL™, Tetanus and Diphtheria Toxoids Adsorbed combined with Component Pertussis Vaccine (TdcP Vaccine) one month after administration. To describe the safety profile of ADACEL™ (TdcP Vaccine) when given as a fifth dose.

Post-marketing evaluation of reactions following receipt of recommended adolescent pertussis vaccine among persons with prior vaccination with acellular vs whole-cell pertussis vaccine. To describe and characterize adverse events occurring after vaccination with REPEVAX® (Tdap-IPV: combination diphtheria, tetanus and acellular pertussis with inactivated poliomyelitis vaccine) or COVAXIS® (Tdap: combination diphtheria, tetanus and acellular pertussis) vaccine among two groups: Group 1 - adolescents 10-14 years of age who participated in study 371-03/01 (and thus received a 5th dose of TRIPEDIA® vaccine) and Group 2 - controls 10-14 years of age who were vaccinated with at least three doses of a whole-cell pertussis vaccine in infancy plus at least one subsequent dose of pertussis vaccine in their 2nd through 7th year of life.

The purpose of this study is to evaluate the immunogenicity and safety of the concomitant administration of Menactra® vaccine and DAPTACEL® vaccine. The main objectives are: Immunogenicity: To evaluate the antibody responses to both vaccines when Menactra vaccine is given concomitantly with DAPTACEL® compared to when either vaccine is given alone. Safety: To evaluate the rate of local and systemic reactions when DAPTACEL® and Menactra vaccines are administered concomitantly compared to when each vaccine is given alone.
