Filter by:This is a randomized, partially blind, placebo controlled, clinical trial evaluating a single intranasal dose of BPZE1 in healthy adults. The study will evaluate a lyophilized formulation of the product, with the goal of testing for the optimal dose for subsequent clinical trials. Fifty healthy adults, 18-49 years of age will be randomized to one of the four following treatment groups in a 3:3:3:1 ratio: 10^7 colony forming units (CFU) of BPZE1 administered by VaxINator device, 10^9 CFU of BPZE1 administered by VaxINator device, placebo administered by VaxINator device, 10^9 CFU of BPZE1 administered by needleless tuberculin syringe. Study duration will be approximately 12 months with a subject participation duration of approximately 6 months. The primary objective of this study is to assess the safety and tolerability of a single intranasal dose of either 10^7 or 10^9 CFU of lyophilized BPZE1 vaccine.
The impact of chronic HIV infection and pregnancy on different aspects of the humoral response to pertussis immunization with the TDaP vaccine will be studied. The parameters will be measured in 3 groups (HIV-infected pregnant, HIV-uninfected pregnant and HIV-uninfected non pregnant) at different time points before and after immunization (7-10 days, 30 days and at delivery). The transfer ratio and the quality of maternal antibodies will be studied in cord blood.
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 purpose of this study was to assess the safety of Boostrix administered on or after the first day of the 27th week of pregnancy by conducting a post-marketing study that provided safety information to the public and healthcare providers. This was one of the largest cohorts of pregnant women vaccinated with Boostrix in the U.S. Through partnership between Kaiser Permanente Southern California (KPSC) and the sponsor, GlaxoSmithKline (GSK), information about the safety of maternal vaccination with Boostrix and maternal and infant adverse events (AEs) in a community setting was gained.
Due to waning of infectious as well as vaccine immunity and lack of vaccination boosters, a large number of adolescents and adults are no longer immunized against Bordetella pertussis, the agent of whooping cough and consequently may contract whooping cough. Furthermore, these populations represent a reservoir of the infectious agent from which the dissemination to non-immune infants is possible, causing severe illness, or even death, in this age group. Few studies have been carried out on whooping cough in developing countries (incidence, contaminator's age, etc.) and, specifically, none have assessed the duration of protection induced by the whole cell pertussis (wP) vaccine mainly presently used in these countries. However, data on the duration of vaccine induced protection are essential to determine i) the usefulness of vaccine boosters and ii) the target age group for these boosters. The aims of the present study are: - To evaluate the proportion of confirmed pertussis cases in infants presenting whooping cough syndrome (WP1a) - To evaluate the proportion of confirmed pertussis cases or healthy carriers among contact cases - To determine origin of the infant's contamination (WP1b) - To determine the duration of protection induced by the wP vaccines used in contact cases and the child population aged 3 to 15 yo (WP1b and WP2) - To bring new scientific evidences documenting the potential need for initiating boosters (WP1b and WP2) - To allow a comparison of the results with those obtained using the same methodology for the acellular pertussis vaccine and/or in other contexts. Potential implications for the use of pertussis vaccines in low and moderate income countries. - To increase local capabilities by the transfer of materials and expertise that will make the diagnosis of pertussis possible in the centres of reference and strengthen a pertussis monitoring network in the implicated countries. - To improve children's health through a better match of the vaccination schedule according to the reality of the situation.
Diphtheria, tetanus and pertussis are common causes of diseases worldwide, with significant morbidity and mortality. The purpose of this study is to assess the immunogenicity, safety and reactogenicity of a single dose of GlaxoSmithKline (GSK) Biologicals' Boostrix vaccine, administered as a booster dose in healthy Russian subjects. An equal number of subjects are expected to be recruited in the following age categories: 4-9 years (children), 10-17 years (adolescents), 18-64 years (adults) and ≥65 years (elderly population). By receiving the Boostrix vaccine, the subjects could be protected against diphtheria, tetanus and pertussis diseases.
Randomized controlled trial of 2 strategies to provide adults with the Tdap vaccine to patients presenting to the emergency department. Rates of vaccination as well as effects on department efficiency will be measured.
This study focus on the genetic changes of B. pertussis clinical isolates. For this panels of B. pertussis isolates has been collected during four periods in different European countries.
This is an observational study designed to describe the immune profile of toddlers and preschoolers with acellular priming after receiving a booster dose of pertussis vaccine.
The study contains three periods: screening, inpatient hospitalization and follow-up. And should be leaded as a randomized placebo-controlled study with in chain order enrolled volunteers and dose escalating.
