Active clinical trials for "Whooping Cough"

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.

The study was designed to compare the safety and immunogenicity of DTap-IPV with DAPTACEL® + IPOL® as the 5th dose booster in children ≥ 4 to < 7 years of age in the US and Puerto Rico who were previously vaccinated with DAPTACEL® and/or Pentacel® vaccines only. Primary Objectives: To compare the pertussis [Pertussis Toxoid (PT), Filamentous Haemagglutinin (FHA), Pertactin (PRN), and Fimbriae Types 2 and 3 (FIM)] booster responses and geometric mean concentrations (GMCs) (as measured by enzyme-linked immunosorbent assay [ELISA]) following DTap-IPV vaccination to those elicited following DAPTACEL® + IPOL® vaccination when administered as a 5th dose. To compare the diphtheria and tetanus booster responses and GMCs (as measured by ELISA) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations when administered as a 5th dose . To compare the Inactivated Poliovirus Vaccine booster responses (as measured by neutralizing assay) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations. Observational Objectives: To compare the polio (types 1, 2, and 3) geometric mean titers (GMTs) following DTap-IPV vaccination with those elicited following DAPTACEL® + IPOL® vaccinations. To assess the safety of DTap-IPV vaccine or DAPTACEL® + IPOL® vaccine when administered as the fifth dose booster vaccine in participants previously vaccinated with DAPTACEL and/or Pentacel vaccines.

This is a follow-up of the primary series vaccination schedule in Study A3L24 (NCT01177722) and booster vaccination in Study A3L27 (NCT01444781). Study Objective: To describe the long-term antibody persistence at 3.5 and 4.5 years of age following a 3-dose primary series vaccination of either DTaP-IPV-Hep B-PRP-T+Prevenar™ (PCV7) +Rotarix™ or Infanrix hexa™+Prevenar™ (PCV7) +Rotarix™ vaccination at 2, 4, 6 months of age and a booster vaccination of DTaP-IPV-Hep B-PRP-T+Prevenar™ (PCV7) or Infanrix hexa™+Prevenar™ (PCV7) at 12 to 24 months of age. Observational Objectives: To describe the long-term antibody persistence by group and by stratification on the age at inclusion of the A3L27 booster study. To describe the effect of one additional oral dose of stand alone poliovirus isotypes 1, 2 and 3 vaccine* on the antibody persistence immune response for poliovirus isotypes (4 vs 5 doses of poliovirus administered).

The purpose of this study is to generate immunogenicity and safety data of an investigational hexavalent DTaP-IPV-Hep B-PRP-T vaccine compared to a control vaccine, Infanrix hexa™ when given along with Prevenar™ and Rotarix™ vaccines. Primary Objectives: To demonstrate the equivalence of immunogenicity of 3 lots of DTaP-IPV-Hep B-PRP-T vaccine 1 month after a 3-dose primary series (2, 4 and 6 months) when given with Prevenar™ and Rotarix™, in terms of immunoresponses. To demonstrate the non-inferiority of the hexavalent DTaP-IPV-Hep B-PRP-T vaccine to the licensed hexavalent Infanrix hexa vaccine when given with Prevenar™ and Rotarix™. Secondary Objectives: To describe in each group the immunogenicity parameters for all antigens for each vaccine To assess the safety profile in terms of solicited and unsolicited adverse events and serious adverse events in each group for each vaccine.

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.

The purpose of this study is to assess the safety of TETRAXIM™ administered in routine clinical practice according to Korea Food and Drug Administration Notification No. 2009-46 "Basic standard for reexamination of new drug" based on the pharmaceutical law in Korea.

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.

This study will be conducted in two stages. In the diphtheria, tetanus, pertussis (DTP) booster phase, subjects will receive a booster dose of Tritanrix-HepB/Hib-MenAC or Tritanrix-HepB/Hiberix (active control) at 15 to 18 or 24 months in a single-blind manner so that the subjects' parents will not know which vaccine was administered to their child. In the Mencevax ACWY phase at 24-30 months, a dose of Mencevax ACWY will be given in an open manner to only those subjects who received less than 4 doses of Tritanrix-HepB/Hib-MenAC. No blood samples will be taken in this safety study.

The purpose of this trial is to clinically confirm that the manufacturing process of the final bulk products of the investigational DTaP-IPV-HB-PRP~T vaccine is consistent. The primary objective is to demonstrate the equivalence of three batches of DTaP-IPV-HB-PRP~T vaccine, in terms of seroprotection and seroconversion rates for the vaccine antigens after the three-dose primary series. The secondary objectives are: To describe in each group, the immunogenicity parameters for all antigens one month after the third dose of the primary series To assess the overall safety in each group one month after the third dose of the primary series.

The purpose of this study is to compare the effectiveness of two strategies of post-exposure prophylaxis (PEP) in healthcare workers (HCWs) who have been vaccinated with acellular pertussis vaccine and have been exposed to pertussis Secondary Objectives include a comparison of the costs of each PEP strategy and an assessment for risk factors associated with healthcare-associated acquisition of pertussis.
