Active clinical trials for "Influenza, Human"

The primary objectives of this study are to evaluate the humoral immunogenicity of mRNA-1010 relative to that of an active comparator against vaccine-matched influenza A and B strains at Day 29, and to evaluate the safety and reactogenicity of mRNA-1010.

This study is an open-label,single center phase Ⅳ clinical trial of combined immunization with quadrivalent influenza vaccine and 23-valent pneumococcal polysaccharide vaccine.The purpose of this study is to evaluate the safety and immunogenicity of combined immunization with quadrivalent influenza vaccine and 23-valent pneumococcal polysaccharide vaccine in the elderly aged 60 years and above.

Comparative trial of tolerability, reactogenicity, safety and immunogenicity of the Flu-M vaccine as compared to the Vaxigrip® vaccine in terms of prevention of influenza in children aged 6 months to 9 years (at the time of the first vaccination).

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

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.

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.

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.

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.

This study is designed to assess the immunogenicity, reactogenicity and safety following vaccination with GSK Biologicals' Fluarix vaccine in children who have previously been vaccinated with two doses of Pandemrix at the age of 6 months-9 years.
