Filter by:This study will compare the efficacy of the Free Air Portable Air Powered Respirator (PAPR) system versus a N95 mask in preventing nasal detection of influenza following an exposure. The investigators hypothesize the use of the Free Air PAPR system will be superior to a N95 respirator at interrupting the exposure of the study participants to aerosolized influenza virus particles.
This study evaluates the safety, tolerability and immunogenicity of IL-YANG quadrivalent vaccine versus IL-YANG trivalent vaccine after a single intramuscular administration in healthy Korean males and females 19 to < 65 years of age.
This is a single centre phase I, double-blind placebo-controlled study to assess reactogenicity, safety and immunogenicity of a live monovalent A/17/Anhui/2013/61 (H7N9) influenza vaccine in healthy male and female adults, 18 through 49 years of age .
The epidemiology and transmission dynamics of influenza in hospitals are only poorly understood, particularly with respect to subjects without symptoms of influenza infection (e.g. without fever, cough, sore throat, nasal congestion, weakness, headache, loss of appetite, or myalgia). Knowledge about whether asymptomatic subjects are able to transmit influenza is of major importance. If they do transmit influenza, vaccination of patients and healthcare workers (HCW) before start of the influenza season, the permanent use of masks by HCW during influenza season, and quarantine for previously exposed inpatients may be the only available measures to reduce the number of influenza transmission events from asymptomatic subjects in acute care hospitals. Closure of this knowledge gap would be of major benefit to infection prevention and control recommendations, and may in turn reduce morbidity and mortality associated with influenza in hospitals through improved patient management.
This prospective annual release study is designed to evaluate the safety of 3 new influenza virus vaccine strains to be included in FluMist Quadrivalent for the 2015-2016 influenza season
Study 201682 is a Phase IIa, randomized, double blind, placebo-controlled four arm outpatient study evaluating the safety, tolerability and clinical effect of danirixin or danirixin + oseltamivir combination in comparison to placebo or oseltamivir twice daily for 5 days in otherwise healthy adults with laboratory confirmed influenza infection. Danirixin is a selective and reversible C-X-C Chemokine Receptor 2 (CXCR2) antagonist that inhibits neutrophil transmigration and activation to areas of inflammation. The study endpoints are intended to test the hypothesis that inhibition of neutrophil activation by approximately 50-60% (as previously measured by cluster of differentiation [CD11b] expression in response to chemokine [C-X-C motif] ligand 1 [CXCL1] stimulation ex vivo in human studies) will not impact safety parameters or worsen clinical manifestations of disease, disease-related events of interest, or viral load, and may possibly improve these parameters when administered within 48 hours of symptom onset. The aim of this exploratory study is to obtain data on the safety, tolerability and clinical effect of GSK1325756 (danirixin [DNX]) alone or in combination with oseltamivir (OSV) in otherwise healthy adults with acute, uncomplicated influenza prior to future evaluation in hospitalized patients with complicated influenza. The primary objective is to assess safety and tolerability of DNX with and without a neuraminidase inhibitor through the evaluation of AEs, SAEs, clinical laboratory tests, vital signs, and electrocardiogram (ECG) parameters. Safety assessments will also include an assessment of disease related events (DREs) of interest and associated antibiotic use. The Influenza Intensity and Impact Questionnaire (FluiiQ™) will be used in the study to document patient reported outcomes (PROs). The screening visit in Australia will be composed of a pre-screen for influenza infection with an influenza rapid antigen test followed by a screen for the remaining eligibility criteria for those subjects with a positive result on the influenza rapid antigen test. FluiiQ is trademark owned by Measured Solutions for Health Private Limited.
A phase 2 a study to assess the safety profile and the effect of VIS410 in healthy subjects after inoculation with influenza A virus (H1N1).
All participants received a single dose of their assigned vaccine on Day 0. They were followed up for immunogenicity and safety through Day 21 post-vaccination. Serious adverse events were collected for 6 months post-vaccination.
This study seeks to determine the incidence and transmission of avian influenza viruses in humans exposed to poultry. Enrolled subjects will be selected from five different rural areas (villages) in the Nile delta region in Egypt where poultry are commonly raised. From those study sites, 2400 healthy subjects will be monitored for 6 years with annual follow up visits to measure sero-prevalence and exposure variables, and more importantly, biweekly or weekly visits to measure incidence of infection, measure secondary transmission rates, monitor symptoms, and assess immunological response. Primary Objectives: - To estimate the incidence of avian influenza (AI) in poultry-exposed human populations. - To estimate sero-prevalent of AI in poultry-exposed human populations. - To investigate potential risk factors associated with AI human infections in poultry-exposed individuals. - To investigate secondary infection risk for household contacts. Secondary Objectives: - To characterize the antigenic and genetic makeup of AI viruses infecting humans. - To monitor the pathogenicity and disease severity of AI viruses causing human infections and the associated immune response. - To investigate the serologic response following confirmed influenza virus infection.
The aim of the study was to generate immunogenicity and safety data in the whole population to support registration of the Quadrivalent Influenza Vaccine (QIV) in India: Primary objective: - To describe in each age group the immune response induced by a single injection (participants aged >9 years) or 2 injections (participants aged 6 months to 8 years) of QIV. Secondary objective: - To describe in each age group the safety profile of QIV.
