Filter by:The purpose of this study is to demonstrate that persons over the age of 13 years can obtain a self-collected nasal swab reliably and safely for subsequent use in the diagnosis of influenza. Similarly, the purpose is to demonstrate that parents or guardians can safely and effectively collect nasal swab specimens from children, ages 0 through 12 years, and others needing assistance in doing so, and that these parent/guardian-collected nasal swabs can also be used in the diagnosis of influenza. Clinical performance of the swabs will be based on the comparison of the performance of the nasal swab that is self- or parent/guardian-collected to one collected from the same specimen donor by a skilled clinical coordinator and used in CLIA (Clinical Laboratory Improvement Amendments)-waived, rapid diagnostic test called Sofia Influenza A+B FIA (fluorescence immunoassay analyzer).
The objectives of this phase 2 study are to evaluate immunogenicity, safety and tolerability of AD07030, a trivalent influenza virus antigens vaccine, given intranasally in 2 doses in healthy adult volunteers.
The overall aim of this study is to evaluate the safety and immunogenicity of Butantan Institute Trivalent Seasonal Influenza Vaccine in comparison with the Sanofi Trivalent Seasonal Influenza Vaccine.
Nudge is a set of methods aimed at helping people adopt a behavior by a gentle prompt, conscious or not. Classically, Nudges rely on heuristics and cognitive biases. These methods have been studied for years in social psychology and are receiving renewed attention since the awarding of the Nobel Prize in economics to Richard Thaler for his work on the application of Nudge to the economy. Health professionals are very inadequately vaccinated (25 to 45% of the population). Some studies have shown that a Nudge based on intent implementation can significantly increase vaccination coverage. However, few studies evaluate the acceptability of Nudge or its application to health professionals. The investigators sought to apply a Nudge based on availability heuristics to health professionals, in order to evaluate its effectiveness and terms of behavior adoption (influenza vaccination) and its acceptability. The investigator's hypothesis is that Nudging is both effective and acceptable and that people found nudging more acceptable if they have been exposed to a nudge.
The primary objective of this study is to describe the safety of the Quadrivalent Influenza Vaccine (QIV). Safety is assessed throughout the study period, and includes solicited injection site and systemic reactions (Day 0 to Day 7 post-vaccination); unsolicited adverse events up to Day 28, and serious adverse events occurring throughout the study.
The purpose of this study is to describe extra-pulmonary clinical manifestations of Influenza virus and Respiratory Syncitial Virus infections in hospitalized adults at a French university hospital.
The aim of this study is to test the effectiveness of communicating the concept of herd immunity on actual influenza vaccine uptake using a randomized controlled trial.
This study evaluates safety, tolerability and immunogenicity of two doses of GHB04L1, a liquid formulation of the replication- deficient influenza A/Vietnam/1203/04(H5N1)-like ∆NS1 virus in healthy adults. Subjects are randomised at a ratio of 2:1 for GHB04L1 (6.8 log10 or 7.5 log10 TCID50/dose/volunteer) or placebo.
The aim of this study is to assess the immunogenicity and safety of a quadrivalent influenza vaccine compared with a trivalent influenza vaccine in participants aged above 3 years.
The purpose of this study is to evaluate the body's immune response at different time points to an FDA-approved seasonal influenza vaccine. By better understanding the way the immune system responds to the influenza vaccine, the investigators can design more effective vaccines against influenza.
