Filter by:Seroprevalence of pertussis among older children and adolescents in Kazakhstan: A cross sectional study. Justification: to describe the distribution of anti-pertussis toxin (PT) antibodies (IgA and IgG) in a population aged 10-18 years old according to sociodemographic characteristics, vaccination history, and risk factors of pertussis infection.
Pertussis 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.
A prospective, multi-center, observational clinical trail. Aim to evaluate the real incidence of COPD pertussis and the impact of pertussis on subaute cough.
A prospective, multi-center, observational clinical trail. Aim to evaluate the real incidence of chronic obstructive pulmonary disease (COPD) pertussis and the impact of pertussis on COPD exacerbation.
The purpose of this study is to evaluate the AFIX-OB model to determine its impact on the change in flu and pertussis (Tdap) uptake, provider knowledge, attitudes and beliefs, and patient knowledge, attitudes and beliefs regarding maternal vaccination. The structure of the model and quality improvement interventions are guided by theory including the elaboration likelihood model and P3 model. These quality improvement measures will be implemented in OB clinics within the Yale New Haven Health System.
The study objective is to assess the immunogenicity and safety of DTaP-IPV combination vaccine administered as a boosting dose to healthy 4 to 6-year-old children who received three doses of primary immunization against diphtheria, tetanus, pertussis, and polio.
Pertussis is resurging worldwide. In Africa alone it is estimated that there are 2.1 million cases and 542,000 deaths from pertussis in infants under 1 year with the highest rates of morbidity and mortality in infants <3 months old, before possible prevention via the infant immunization programme1. To protect these most vulnerable infants, the World Health Organisation (WHO) recommends Tdap vaccination as safe in pregnancy and recommends the use of wP vaccines within the EPI. Maternal antibody following aP vaccination can interfere with infant anti-pertussis antibody responses post infant EPI vaccination, which is of concern in high burden settings such as Uganda. There are therefore multiple factors in this population which may influence the effect of pertussis immunization in pregnancy, and which have not been studied, most notably HIV infection and interference with wP vaccines in infants. The immunogenicity of Tdap in HIV-infected pregnant women has not yet been examined. In addition, to date, the effect of maternal vaccination, placental transfer and infant antibody responses in HEU infants have not been studied at all. There are no studies examining the immune response to wP vaccine administered to infants (EPI recommendation) whose mothers received aP in pregnancy.
Recruitment of individuals primed during childhood with TdaP (tetanus, diphtheria , acellular pertussis) vaccine, and administration of an Adacel booster with blood sample collection at various time points before and after vaccination. Collection of blood sample volumes will be large enough to allow assessment and comparison of multiple assays that evaluate cell-mediated immune (CMI) responses and other biomarkers following the administration of pertussis vaccinations. The ultimate objective would be to utilize these validated assays for evaluation of pertussis clinical trial results or development of new pertussis vaccine formulations.
A CPA platform based on the CRISPR technology is going to established to achieve the goal of detecting pathogenic bordetella and drug resistance genes in one step. The accuracy of this platform will be checked through prospective diagnostic test evaluation methods. Bordetella pertussis isolation culture and identification would be set as a gold standard method.
In July 2015-November 2016, a phase II/III randomized, observer-blind,controlled study of two acellular Pertussis vaccines (aP standalone and TdaP combined vaccines) manufactured by BioNet-Asia Co., Ltd. (Bionet) and chemically-detoxified Adacel Tdap vaccine was conducted in Bangkok, Thailand in healthy participants aged 12-17 years (Protocol No. TDA202; http://clinicaltrials.in.th;Study ID:TCTR20150703002). A total of 450 participants 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 participants enrolled at each study site. During the study, the participants 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 participants 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-inactivated Tdap vaccine (Adacel) at 5 years after previously immunized in the TDA202 study.
