Filter by:This study aims to determine the sero-prevalence of anti-pertussis antibodies among healthcare professionals at hospital centres in Spain.
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 the study is to further characterize the safety and immunogenicity of Menactra® in the population <2 years of age when administered alone and when the second dose is administered concomitantly with the 4th dose of Pentacel®, a licensed pediatric vaccine. Primary Objectives: - To evaluate and compare the antibody responses to meningococcal serogroups A, C, Y, and W-135 induced by 2 injections of Menactra® in subjects aged 9 months at the first vaccination visit and 15 to 18 months at the second vaccination visit. - To evaluate and compare the antibody responses to Pertussis (pertussis toxoid [PT], filamentous haemagglutinin [FHA] and pertactin [PRN]) antigens induced by a dose of Pentacel® when administered concomitantly with Menactra® to those elicited by a dose of Pentacel® administered alone. - To evaluate and compare the antibody responses to polyribosylribitol phosphate (PRP), tetanus and diphtheria antigens induced by a dose of Pentacel® when administered concomitantly with Menactra® to those elicited by a dose of Pentacel® alone. Observational Objectives: - To describe the safety profile (immediate unsolicited AEs within 30 minutes of each trial vaccination, solicited reactions within 7 days of each vaccination, unsolicited AEs within 30 days of each vaccination, and serious adverse events [SAEs] throughout the course of the trial from Day 0 up to Day 30 after the last trial vaccination[s]) in all trial groups - To describe the antibody responses to meningococcal serogroups A, C, Y, and W-135, measured by SBA HC, 30 days after the second Menactra® administration - To describe the antibody responses to Pentacel® (PT, FHA, PRN, FIM, diphtheria, tetanus, polio, PRP) measured by enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), or functional assays.
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.
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.
The study will assess the safety of Pentaxim® vaccine as a three-dose primary vaccination at 2, 3, and 4 months of age in order to meet the regulatory requirements for the license renewal as for any other product registered in China, and to generate additional clinical data using the three-dose primary vaccination schedule in some other Chinese provinces. Primary Objective - To describe the safety after administration of PENTAXIM® at 2, 3, and 4 months of age in the study population.
This study will evaluate immunogenicity, safety and tolerability of fully liquid pentavalent vaccine (DTwP-Hib-HepB Vaccine) in infants 6-8 weeks of age.
This study will assess the immunogenicity and safety of GlaxoSmithKline (GSK) Biologicals' (formerly SB Biologicals') DTPa-HBV-IPV/Hib (Infanrix hexa™) vaccine compared with separate administration of DTPa-HBV-IPV (Infanrix penta™) and Hib (Hiberix™) vaccine administered at 3, 5 and 11 (or 12) months of age.
