Filter by:Despite good vaccination coverage, included in national immunization programs in developed countries, the number of reported pertussis cases is rising, also in very young infants. Current immunization strategies fail to protect infants too young to be immunized with the licensed vaccine. Different strategies are possible to close the gap of susceptibility between the loss of maternal antibodies and protection by vaccination. The main aim of the present study is to measure the influence of an adult pertussis booster in pregnant women, on the titer and duration of maternal antibodies in their infants. Early humoral immunity will be assessed and the influence on vaccine response of the infant measured. The present study offers the opportunity to have new insights in neonatal immunological mechanisms against pertussis and a better understanding in strategies to protect infants against pertussis.
This study is designed to assess the immunogenicity and safety of tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine (ADACEL®, Tdap vaccine) as a booster dose in adolescents in Japan. Primary Objective: - To assess the immunogenicity of Tdap (SP306) when administered as a single dose in Japanese adolescents Secondary Objective: - To assess the safety of Tdap vaccine when administered as a single dose in Japanese adolescents.
The aim of this study is to describe immunogenicity of a single booster dose of Adacel vaccine versus Boostrix vaccine among approximately 420 adolescents 11 to <13 years of age. Primary objective: - To describe seroprotection rates against tetanus and diphtheria in subjects randomized to receive either Adacel or Boostrix vaccine. Observational objectives: - To describe pre- and post-vaccination tetanus, diphtheria, and pertussis geometric mean antibody concentrations (GMCs) in subjects randomized to receive either Adacel or Boostrix vaccine. - To describe booster response rates against tetanus, diphtheria, and pertussis in subjects randomized to receive either Adacel or Boostrix vaccine. - To describe the rates of adverse events (AEs) immediately post-vaccination, and the rates of unsolicited AEs and serious adverse events (SAEs) following vaccination with Adacel or Boostrix vaccine from Visit 1 through Visit 2.
This study aims to determine the burden of pertussis infection among adolescents and adults with prolonged cough in four Asian countries, namely Malaysia, Philippines, Taiwan and Thailand. This study also aims to assess the health economic (HE) impact of pertussis.
Primary objective: This is a descriptive study and the primary objective is to determine the incidence of injection site and systemic adverse events after Triaxis administration as a 5th dose of tetanus, diphtheria and acellular pertussis vaccine in 4-6 year old children
The purpose of this study is to collect safety information following routine vaccination with Infanrix-IPV among infants and children in Korea.
Longitudinal survey in Northern Senegal to investigate the environmental factors modulating the immune response to childhood vaccines and to malaria. A cohort of 410 children aged 1 to 10 from 5 villages of the Senegal River Valley(Podor District) was followed-up for 18 months. During that period, 5 visits have been made to the villages to assess the immunological and nutritional status of the children.
This study will evaluate the safety and efficacy of 9 different vaccines containing aP (acellular pertussis) and TdaP (acellular pertussis, tetanus and diphtheria) in healthy subjects 18 to 40 years of age.
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 describe the safety and immunogenicity of repeat administration of Adacel vaccine approximately 10 years following initial administration of the vaccine. Antibody levels prior to revaccination will also be used to characterize antibody persistence following initial vaccination 10 years earlier. Primary Objectives: - To compare seroprotection rates against tetanus and diphtheria induced by Adacel vaccine to those induced by Td Adsorbed vaccine. - To compare booster response rates against tetanus and diphtheria induced by Adacel vaccine to those induced by Td Adsorbed vaccine. - To compare anti-pertussis geometric mean antibody concentrations (GMCs) induced by Adacel vaccine to the GMCs induced by Daptacel® vaccine given to infants. Secondary Objectives: - To describe the rates of immediate reactions, solicited reactions, unsolicited adverse events (AEs), and serious adverse events (SAEs) following vaccination with Adacel or Td Adsorbed vaccine. - To describe booster response rates for pertussis antigens following revaccination with Adacel vaccine.
