Active clinical trials for "Influenza, Human"

Comparative assessment of the tolerability, safety and immunogenicity of the Flu-M vaccine vs. the Ultrix® vaccine by single vaccination of children aged 6 to 17 years.

This is a Phase II randomized, double-blind, placebo-controlled trial in 120 males and non-pregnant females, 18 to 49 years old, inclusive, who are in good health and meet all eligibility criteria. This clinical trial will be conducted at 3 United States sites and is designed to assess the safety, reactogenicity, and immunogenicity of two priming doses of M-001 followed by a seasonal quadrivalent inactivated influenza vaccine (IIV4). The duration of this trial for each subject will be approximately 7 months. The entire study duration will be approximately 24 months. The primary objectives are: 1) To assess the safety as measured by vaccine related adverse events, reactogenicity, and laboratory adverse events of two doses of M-001 vaccine, each dose administered approximately 21 days apart; and 2) To assess the T cell responses to M-001 component peptides following two doses of M-001.

80 subjects (healthy adults) will be randomized to receive the seasonal flu vaccine either by needle & syringe or by the MIT needle-free injector (Med-Jet MIT H4™ & Disposable Cartridge). The study will be conducted after the normal flu season has passed (ie: March-April). Half of those randomized to standard vaccination (n=20) will receive vaccine drawn from a multi-dose vial while the other half (n=20) will receive vaccine drawn from a single use vial. The same vaccine as the multi-dose vial will be delivered to the other half of the subjects (n=40) using the MIT injector. How long it takes to prepare and deliver the vaccines will be assessed (a time-motion study). Subject acceptance before and after injection will be assessed as well as local and systemic side effects. Standard serologic measures of immune response to flu vaccination (ie: antibodies) will determine whether the Med-Jet H4 injector induces the same kind of immune response as needle & syringe delivery.

Most of family physicians (FPs) use advertising in their waiting rooms in order to educate patients. Our objective was to assess an advertising campaign for influenza vaccination using posters and pamphlets in FPs' waiting rooms. Registry based 2/1 cluster randomized controlled trial. Clusters gathered the listed patients over the age of 16 of 75 randomized FPs. The trial was conducted during the 2014-2015 influenza vaccination campaign. Intervention group, 25 FPs received and exposed in their waiting rooms pamphlets and one poster promoting the influenza vaccination campaign (added to the usual mandatory information). Control group (50 FPs), usual waiting room. The main outcome was the number of vaccination units delivered in pharmacies. Data were first extracted for 2013-2015 from the SIAM-ERASME claim database of the Health Insurance Fund of Lille-Douai (Northern France). The association between the intervention and the main outcome was assessed trough a generalized estimating equation.

The purpose of this study is to evaluate the immune response, safety and reactogenicity after receiving combined DTPa-IPV/Hib vaccine when administered as a three-dose primary vaccination course at 3, 4.5 and 6 months of age and as a booster dose at 18 months of age in Russian healthy children according to the Russian immunisation schedule

In this open label, single centre, pilot randomized controlled clinical trial the investigators aim to compare the immunogenicity and safety of a new influenza vaccination strategy consisting in the topical administration of imiquimod at the injection site before vaccination vs. a standard intramuscular vaccine injection in SOT recipients and HIV-infected individuals. The investigators planned to enroll 70 outpatients patients (50% solid-organ transplant recipients and 50% HIV-infected patients) regularly followed at the Transplantation center and the Infectious disease outpatients' clinics of the Lausanne University Hospital. Study participants will be randomized in a 1:1:1 ratio to receive the standard intramuscular vaccine (control group) or a topical application of an imiquimod containing cream followed by intramuscular (imiquimod-IM) or intradermal (imiquimod-ID) vaccine injection. After vaccination participants will be followed for a period of 180 days. Blood samples will be drawn at baseline and at day 21 and 180 for assessment of immunogenicity. Safety outcomes will be assessed immediately after vaccine administration, and at day 7 (phone call), 21 and 180.

Influenza is an acute respiratory disease caused by influenza viruses. There are three types of the virus including A, B and C. Both type A and type B viruses can cause acute febrile respiratory tract infection, characterized by sudden fever, headache, muscle pain, cough, sore throat, nasal congestion and general malaise. The main transmission of influenza is through those highly contagious aerosol droplets containing influenza virus passed from infected people to susceptible population. Each year in the fall and winter infection of influenza is widespread in various age groups, with high incidence rate. Although influenza is generally a self-limiting disease, but in children, the elderly (especially those above 65 years old and those with chronic heart, lung, kidney, liver, blood or metabolic diseases such as diabetes or other certain diseases) and those with poor immunity function, influenza can easily lead to serious flu complications such as pneumonia, resulting in severe increase of morbidity and mortality. In order to evaluate safety and immunogenicity of a quadrivalent influenza vaccine produced by Jiangsu Jindike Biotechnology Co., Ltd. a phase III clinical trial is planned to conduct in healthy Chinese subjects aged 3 years and older.

This study evaluates the safety of Quadrivalent Influenza Virus Vaccine in Healthy People Aged years 3 to 60.40 Subjects will be equally divided into 2 groups,including 3-17 years old and 18-60 years old.Adult group first receive one dose of Quadrivalent Influenza Virus Vaccine.Then minors group also receive one dose of Quadrivalent Influenza Virus Vaccine after 7 days.

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 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 Committee for Human Medicinal Products (CHMP) Note for Guidance (NfG) Committee for Propriety Medicinal Products (CPMP) - CHMP NfG CPMP/BWP/214/96.
