Active clinical trials for "Influenza, Human"

The purpose of this study is to test an investigational vaccine known as "VAX161C." An "investigational" vaccine is one that is not licensed for commercial use in the by the United States (US) by the US Food and Drug Administration (FDA). VAX161C is a vaccine for the influenza A virus subtype H5N1 avian influenza virus (bird flu). In this study, the subject will receive the VAX161C vaccine at one of six doses to see which dose is the best. VaxInnate wants to find out how safe these doses of vaccines are and how well they are tolerated by people who receive them. To measure how effective each type of the vaccine is, VaxInnate will test the ability of the body to develop an immune response, which means how the body recognizes and defends itself against the influenza virus.

This protocol was designed to evaluate the safety, clinical tolerability and immunogenicity of the Trivalent Influenza Virus Vaccine (TIVf, purified surface antigen, inactivated, egg derived), Northern Hemisphere formulation 2012/2013. The principal aim was to provide safety and immunogenicity data, in compliance to current EU Guidelines, with the intent of obtaining marketing approval of the vaccine formulation intended for use prior to the next influenza season in the Northern Hemisphere. The antibody response to each influenza vaccine antigen, was measured by hemagglutination inhibition (HI) and single radial hemolysis (SRH) at approximately 21 days postimmunization in adult and elderly subjects. The safety and immunogenicity of a single intramuscular (IM) injection of the vaccine was evaluated in compliance with the requirements of the current EU recommendations for clinical trials related to yearly licensing of influenza vaccines (CPMP/BWP/214/96).

The objectives of this single arm study are to evaluate the immune response and safety profiles of two injections of an inactivated whole-virion vaccine containing aluminum hydroxide adjuvant, AdimFlu-W (H5N1), against influenza A (H5N1) in healthy adults.

To evaluate the safety profile of two intranasal doses of LAIV A/17/turkey/Turkey/05/133 (H5N2) in healthy adults.

The purpose of this pilot evaluation is to help determine the feasibility and power needed to prospectively evaluate relative effectiveness of high-dose influenza vaccine in preventing influenza mortality and hospitalization in a nursing home population in the U.S., compared to the standard-dose influenza vaccine.

The aim of the study is to demonstrate safety and immunogenicity of the quadrivalent influenza intradermal (QIV-ID) vaccine compared to the trivalent influenza vaccine (TIV) containing the B strain from the primary (Yamagata) lineage (TIV-ID1) and the trivalent influenza vaccine containing B strain from the alternate (Victoria) lineage (TIV-ID2) vaccines in producing protection against four strains of influenza virus. Primary Objective: To demonstrate that QIV-ID induces an immune response (as assessed by hemagglutination inhibition (HAI) geometric mean titers (GMTs) and seroconversion rates) that is non-inferior to responses induced by TIV-ID1 and TIV-ID2 for the 4 virus strains at 28 days post-vaccination. Secondary Objectives: To demonstrate that each B strain in QIV-ID induces an immune response (as assessed by HAI GMTs and seroconversion rates) that is superior to the response induced by the TIV-ID that does not contain the corresponding B strain. To describe the rate of post-vaccination seroprotection induced by QIV-ID and TIV-ID. To describe post-vaccination immunogenicity stratified by age (18-49 years and 50-64 years), race, ethnicity, gender, previous vaccination status, and baseline seropositivity status. To describe the safety profile for subjects who receive QIV-ID and TIV-ID. Observational Objectives: To demonstrate non-inferiority of QIV-ID compared to TIV-ID in terms of all Grade 2 or Grade 3 solicited systemic reactions combined To demonstrate non-inferiority of QIV-ID compared to TIV-ID in terms of all Grade 3 solicited injection site reactions combined.

This study has been designed to evaluate the safety and immunogenicity of two different formulations of FP-01.1 as well as build on the data set from the first in human study FP-01.1_CS_01. It is anticipated that the results of this Phase I study will inform the best formulation of the vaccine to evaluate in efficacy studies.

The purpose of this study is to determine whether Yili Lactoferrin ShuHua Milk are effective in reducing the occurrence of flu symptoms.

The present study will evaluate the safety in healthy people aged 1- 45 years (male and female) after single intramuscular (IM) dose of trivalent subunit inactivated influenza vaccine till the 30-days follow-up period.

The purpose of this study is to see how much antibody (proteins produced by the immune system that help fight infections) the body makes after getting a flu vaccine. Researchers will also look at how the body reacts to the flu vaccine and how it affects the babies of pregnant women. The study will enroll approximately 240 women ages 18-39 years, including 180 pregnant women in their second or third trimester of pregnancy (at least 14 weeks pregnant) and 60 non-pregnant women. Participants will be randomly (by chance) assigned to 1 of 3 vaccine groups. Each participant will receive one shot of a 2010-2011 flu season licensed vaccine. The vaccine will be given as an intramuscular injection (shot in the muscle) in the upper arm. Study procedures include pregnancy testing, blood draws, and memory aids. Patient participation may be up to 8 months. The information from this study will help guide researchers in developing flu vaccines for pregnant women.
