2-year Follow-up After a Single Dose Acellular Pertussis Vaccination
PertussisIn July 2015-November 2016, a phase II/III randomized, observer-blind,controlled study of two acellular Pertussis vaccines (aP standalone and TdaP combined vaccined) manufactured by BioNet-Asia Co., Ltd. (Bionet) and chemically-detoxified Adacel Tdap vaccine was conducted in Bangkok, Thailand in healthy subjects aged 12-17 years (Protocol No. TDA202; http://clinicaltrials.in.th; Study ID:TCTR20150703002). A total of 450 subjects were enrolled into the study at 2 study sites (Site No.1:Faculty of Medicine Siriraj Hospital; Site No.2:Vaccine Trial Centre (VTC), Faculty of Tropical Medicine, Mahidol University) with equal number of 225 subjects enrolled at each study site. During the study, the subjects had been randomized in a 1:1:1 ratio to received intramuscularly a booster dose (0.5 mL) of the study vaccines. In this current study, persistence of pertussis antibodies induced by a booster dose of recombinant acellular Pertussis based vaccines (Pertagen and Boostagen) manufactured by Bionet will be evaluated and compared to the conventional chemically-detoxified Tdap vaccine (Adacel) at 2 years after previously immunized in the TDA202 study.
3-year Follow-up After a Single Dose Acellular Pertussis Vaccination
PertussisIn July 2015-November 2016, a phase II/III randomized, observer-blind,controlled study of two acellular Pertussis vaccines (aP standalone and TdaP combined vaccined) manufactured by BioNet-Asia Co., Ltd. (Bionet) and chemically-detoxified Adacel Tdap vaccine was conducted in Bangkok, Thailand in healthy subjects aged 12-17 years (Protocol No. TDA202; http://clinicaltrials.in.th;Study ID:TCTR20150703002). A total of 450 subjects were enrolled into the study at 2 study sites (Site No.1:Faculty of Medicine Siriraj Hospital; Site No.2:Vaccine Trial Centre (VTC), Faculty of Tropical Medicine, Mahidol University) with equal number of 225 subjects enrolled at each study site. During the study, the subjects had been randomized in a 1:1:1 ratio to received intramuscularly a booster dose (0.5 mL) of the study vaccines. This is further follow-up from TDA202 clinical trial, which was completed on 29 November 2016. Target population for this study is the group of subjects who had received one dose of one of the three study vaccines in the TDA202 trial at site VTC and who had completed the study follow-up at 1-year after vaccination (223 subjects). In this current study, the long-term persistence of pertussis antibodies induced by a booster dose of recombinant acellular Pertussis based vaccines (Pertagen and Boostagen) manufactured by Bionet will be evaluated and compared to the conventional chemically-detoxified Tdap vaccine (Adacel) at 3 years after previously immunized in the TDA202 study.
Study of the Environmental Factors Modulating Children Immune Response in Northern Senegal
Whooping CoughMalaria1 moreLongitudinal 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.
Seroprevalence of Pertussis Among Children and Adolescents in Croatia
ImmunogenicityVaccinePertussis is a vaccine preventable disease caused by Bordetella pertussis. Older children and adolescents with pertussis continue to be a significant source of infection for incompletely vaccinated infants who are in harm for developing severe disease. The primary objective of our study is to estimate the duration of protection elicited by the current vaccination schedule against pertussis in Croatia.
Antibody Persistence in Healthy Children After Primary and Booster DTaP-IPV-Hep B-PRP-T Vaccine...
DiphtheriaTetanus3 moreThe purpose of this study is to evaluate the long term immunogenicity produced in children by the investigational hexavalent vaccine (DTaP-IPV-Hep B-PRP-T) given in Study A3L15 (NCT 00362336). Primary Objective: To describe the antibody long term 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 or CombAct-Hib™ + Oral poliovirus vaccine (OPV) + Engerix™ B vaccination at 6, 10 and 14 weeks of age and a booster vaccination of DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + OPV at 15-18 months
Surveillance Program to Determine Product Specific Rates of Invasive Hib Disease
Haemophilus InfectionsDiphtheria3 moreTo monitor the occurrence of invasive Hib disease over time and to determine product-specific rates of invasive Hib disease within the monitored population.
Maternal Antibody in Milk After Vaccination
PertussisVaccination2 moreSingle-centre observational pilot study exploring pertussis specific antibody concentration in the breastmilk of women vaccinated against pertussis in pregnancy at different gestational ages. This study is made up of two stages: first stage to confirm recruitment methods and optimise the laboratory assay and a second stage to complete recruitment for the pilot study.
