Active clinical trials for "Whooping Cough"

This is a follow-up of the primary series vaccination schedule in Study A3L24 (NCT01177722). The objectives are: To describe the antibody persistence to any antigen contained in the investigational DTaP-IPV-Hep B-PRP-T vaccine and Infanrix hexa™ prior to the booster dose To describe the safety and immunogenicity of the booster dose of either DTaP-IPV-Hep B-PRP-T or Infanrix hexa™ vaccine. To describe the immunogenicity of a booster dose of Prevenar™ given at 12 to 24 months.

This study aims to assess and confirm the adequate immunogenicity and safety profile of the Sanofi Pasteur's DTaP-Hep B-IPV-PRP-T fully liquid combined hexavalent vaccine administered in HIV-exposed uninfected infants and in HIV-exposed infected infants. The primary objectives of the study are: To evaluate the immunogenicity of the study vaccine 1 month after the 3-dose primary series in HIV-exposed infected and in HIV-exposed uninfected infants. To describe the persistence of all antibodies before receipt of the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. To evaluate the immunogenicity of the study vaccine 1 month after the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants. The secondary objectives of the study are: To describe the safety profile after each and all doses of the study vaccine administered as a 3-dose infant primary series in HIV-exposed infected and in HIV-exposed uninfected infants. To describe the safety profile of the study vaccine administered as a booster in HIV-exposed infected and in HIV-exposed uninfected infants.

This study evaluated the seroprevalence of Bordetella pertussis antibodies and anti-pertussis antibody response after a single dose of reduced-antigen, combined diphtheria, tetanus, and acellular pertussis vaccine (Tdap) in pregnant Thai women. All seronegative participants received Tdap, while seropositive participants were equally randomized into 2 groups. Half of seropositive participants received Tdap and the other half received tetanus-diphtheria (Td) as standard protocol.

Pertussis, diphtheria and tetanus are seriously infectious diseases in children. Since using of the adsorption diphtheria-tetanus-whole-cell pertussis (DTwP), it greatly reduced incidence of the three kinds of diseases. But the thallus of pertussis in the vaccine may cause more side reactions after vaccination. Since 2000, the basic immunization DTwP vaccine has been replaced by adsorption tetanus-diphtheria-acellular pertussis vaccine in American. In 1995, DTaP was successfully developed in China, and have been used in EPI at present. Because of effective immunity and little side reaction, DTaP has been widely recognized and accepted by the parents.

This study evaluates the safety and immunogenicity of a higher dose formulation of a new live attenuated vaccine, BPZE1, intended to prevent Bordetella pertussis nasopharyngeal colonization and pertussis disease, and investigates whether higher doses of BPZE1 induce the live vaccine to colonize subjects' nasopharynx. The study is a Phase Ib (high dose), single centre, dose-escalating, placebo-controlled study of the live attenuated B. pertussis strain BPZE1 given as a single intranasal dose to healthy adult volunteer.

This is a randomized, partially blind, placebo controlled, clinical trial evaluating a single intranasal dose of BPZE1 in healthy adults. The study will evaluate a lyophilized formulation of the product, with the goal of testing for the optimal dose for subsequent clinical trials. Fifty healthy adults, 18-49 years of age will be randomized to one of the four following treatment groups in a 3:3:3:1 ratio: 10^7 colony forming units (CFU) of BPZE1 administered by VaxINator device, 10^9 CFU of BPZE1 administered by VaxINator device, placebo administered by VaxINator device, 10^9 CFU of BPZE1 administered by needleless tuberculin syringe. Study duration will be approximately 12 months with a subject participation duration of approximately 6 months. The primary objective of this study is to assess the safety and tolerability of a single intranasal dose of either 10^7 or 10^9 CFU of lyophilized BPZE1 vaccine.

The objective of this study is to describe the safety of Adacel® vaccination in adults subjects in Vietnam. This study is conducted in accordance with Vietnamese regulation in support to Adacel® registration. Primary objective: To monitor the adverse effects of the vaccine ADACEL® from day 0 to day 30 after immunization.

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.
