Filter by:This prospective randomized controlled trial studies the efficacy and safety of treating influenza with the reconciling exterior and interior therapy. A total of 300 cases of seasonal flu in Beijing is to be collected, and divided into one treatment group and two control groups. Patients in the treatment group will receive Liugan Shuangjie Heji, while patients in control groups will receive Shufeng Jiedu Capsule and Oseltamivir Phosphate Capsule respectively, for a course of 5 days. The study assesses the efficacy and safety of treating influenza with the reconciling therapy based on the following outcome measures: the time it takes from the medicine intake to 0.5℃ drop of body temperature, and the time it takes for the body temperature to return to normal.
The purpose of this study is to conduct a pilot study to explore the potential use of routinely collected data in General Practitioner (GP) practices to conduct enhanced safety surveillance of seasonal influenza vaccines in the UK, as recommended in the EMA interim guidance on enhanced safety surveillance for seasonal influenza vaccines in the EU.
The investigators' hypothesis is that the administration of Fluzone® High-Dose with booster to all patients with monoclonal gammopathies (irrespective of age) will lead to seroconversion rates exceeding 50% and more importantly, will reduce influenza-related morbidity, reduce interruptions in cancer therapy and may reduce disease progression at the end of the flu season
The aim of the study is to evaluate the safety and immunogenicity of the 2015-2016 formulations of Fluzone Quadrivalent and Fluzone Intradermal Quadrivalent vaccines in adults 18 to < 65 years of age, and of the 2015-2016 formulations of Fluzone Quadrivalent and Fluzone High-Dose vaccines in adults ≥ 65 years of age. Primary Objective: - To describe the safety of the 2015-2016 formulations of Fluzone Quadrivalent and Fluzone Intradermal Quadrivalent vaccines in adults 18 to < 65 years of age and the safety of the 2015-2016 formulations of Fluzone Quadrivalent and Fluzone High-Dose vaccines in adults ≥ 65 years of age. Observational Objectives: - To describe the immunogenicity of the 2015-2016 formulations of Fluzone Quadrivalent and Fluzone Intradermal Quadrivalent vaccines in adults 18 to < 65 years of age and the immunogenicity of the 2015-2016 formulations of Fluzone Quadrivalent and Fluzone High-Dose vaccines in adults ≥ 65 years of age. - To evaluate the compliance, in terms of immunogenicity, of each study vaccine (Fluzone Quadrivalent, Fluzone Intradermal Quadrivalent, and Fluzone High-Dose) in the applicable age group with the historical requirements of the CHMP NfG CPMP/BWP/214/96.
A multi-centre, randomized, placebo controlled, trial. Participants will be patients either ≥65 years or with one or more high risk conditions presenting to one of four academic emergency departments in Edmonton or Calgary with influenza-like illness. The investigators will test for influenza using a point-of-care rapid test and if positive for influenza participants will be randomized to oseltamivir or placebo and followed prospectively. The primary outcome will be hospitalization.
This study evaluates how different methods of early exposure to influenza (natural infection, live attenuated influenza vaccination, inactivated influenza vaccination) initially stimulate immunity and poise the immune system to respond to a future challenge with the inactivated influenza vaccine.
The investigators will explore in an experimental medicine healthy human model of immunisation, whether switching the route of sequential administration of licensed influenza vaccines can result in an immune response that is broader in its ability to recognise different substrains of influenza viruses. The investigators will do this by initially giving an immunisation with a nasal or an injected vaccine, and then switching subjects over to receive a second dose one month later (when the cellular component of immunity will have matured) via the opposite route (nasal->injected or injected->nasal). The investigators will use research assays that can map the different parts of the influenza virus that the vaccinated person's immune cells recognise at baseline, after the first immunisation, and then again after the second, to see if the breadth of the recognition has broadened to include new strains or virus components. Should this pilot study give an indication that the breadth has widened (rather than just a further boost to the same responses seen after the first immunisation) it will provide justification for a larger study in which statistical significance may be powered for observed changes. The study is funded by ADITEC, which is a collaborative research programme that aims to accelerate the development of novel and powerful immunisation technologies for the next generation of human vaccines.
The purpose of this study is to evaluate the immunogenicity and safety of TAK-850 administered subcutaneously as a single dose versus influenza HA vaccination in an exploratory manner.
The Sanofi Pasteur Fluzone Intradermal Quadrivalent vaccine (Fluzone QIV-ID) Pregnancy Registry will be a prospectively recruited pregnancy surveillance program designed to collect to collect and analyze information on vaccine exposures, pregnancy outcomes, and fetal and offspring outcomes on pregnant women exposed to Fluzone QIV-ID vaccine.
The aim of the study is to assess the safety and immunogenicity of two formulations of the high-dose quadrivalent influenza vaccine compared to the licensed high-dose trivalent influenza vaccine control in healthy elderly subjects aged 65 years of age and above. Primary objectives: - To describe the safety profile of all subjects in each study group. - To demonstrate that the high-dose quadrivalent influenza vaccine induces an immune response (as assessed by HAI geometric mean titers (GMTs) that is non-inferior to responses induced by the licensed high-dose trivalent influenza vaccine for the 3 common virus strains at 28 days post-vaccination. Secondary objectives: - To describe post-vaccination immunogenicity for the 4 virus strains (as assessed by seroconversion and seroprotection) for subjects who receive the high-dose quadrivalent influenza vaccine and the licensed high-dose trivalent influenza vaccine. - To describe post-vaccination immunogenicity for the 4 virus strains (as assessed by GMTs, seroconversion, and seroprotection) for subjects who receive the high-dose quadrivalent influenza vaccine and the investigational high-dose trivalent influenza vaccine.
