Active clinical trials for "Whooping Cough"

Pediacel™ is currently licensed in the UK for use as a 3 dose regimen for the active immunisation of infants against Diphtheria, Tetanus, Pertussis, Poliomyelitis and invasive infections caused by Haemophilus influenzae type b. However there are currently no clinical data supporting the use of Pediacel™ using a 3, 5, and 12 months of age vaccination schedule. This study is designed to provide safety and immunogenicity data to support the use of Pediacel™ according to a 3, 5, and 12 months schedule.

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/ vaccine response rates to Pertussis antigens (PT, FHA) of Sanofi Pasteur's DTaP-IPV combined vaccine versus historical reference (Study E2I03294 - France).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.

GSK Biologicals' dTpa vaccine has recently been approved by the US Food and Drug Administration (FDA) for booster vaccination of adolescents aged 10 to 18 years. The ACIP has recently issued provisional recommendations for universal adult Tdap vaccination. The current study will provide pivotal data in support of extending the age range for Boostrix vaccine to include adults 19-64 years of age.

The purpose of the study is to evaluate the immunogenicity, safety and reactogenicity of a booster dose of DTPw-HBV/Hib-MenAC compared to DTPw-HBV/Hib given to healthy subjects at 15 to 24 months of age primed with 3 doses of Tritanrix-HepB/Hib-MenAC in study 100480. Antibody persistence will be evaluated at 24 to 30 months. Immunogenicity, safety and reactogenicity of a dose of Mencevax ACWY given at 24 to 30 months will also be evaluated when given to subjects not boosted with a MenA conjugate and/or MenC containing vaccine.

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.

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 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 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.

Young infants are most vulnerable to severe disease and even death when infected with Bordetella pertussis. The current vaccines and vaccination programs do not guarantee protection of neonates from this disease. Maternal acquired pertussis-specific antibodies show low concentrations with short persistence in newborns creating a susceptibility gap for infection between birth and the first vaccinations. A possible strategy to protect infants from birth is pertussis vaccination during pregnancy, which will increase the amount of passively transferred maternal antibodies. However, little is known regarding the effect of high titers of maternal antibodies on the infants immune responses to different pertussis vaccines (whole cell versus acellular). Humoral immune responses will be assessed in infants receiving whole cell versus infants receiving acellular pertussis vaccines. Functionality of the antibodies will also be analyzed.
