Active clinical trials for "Influenza, Human"

This phase I-like, open-label, monocenter, descriptive, single-arm clinical safety study will investigate the Shenzhen quadrivalent influenza vaccine (Shz QIV) in 100 participants aged 6 months and older in China. Participants aged 9 years or more will receive a single dose of Shz QIV, and participants aged 6 months to 8 years will receive two doses of Shz QIV administered 28 days apart.

The aim of the study was to assess the immunogenicity and safety of Fluzone Quadrivalent influenza vaccine Southern Hemisphere (SH) 2015 formulation in participants aged 18 to 60 years as well as in participants 61 years or older. The objectives were: To evaluate the compliance, in terms of immunogenicity, of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation with the requirements of the European Medicines Agency (EMA) Note for guidance (NfG) CPMP/BWP/214/96 To describe the immunogenicity of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation To describe the safety of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation

"Multimeric-001" (M-001) contains conserved, common linear influenza epitopes that activate both cellular and humoral arms of the immune system against a wide variety of influenza A and B strains. Apart from its direct action, M-001 is an attractive candidate for priming immune responses to pandemic influenza vaccine in the adult population. The current clinical study was designed to assess M-001's standalone and priming action in subjects aged 18-60 years old. This is a Phase IIb study comprising 222 participants. Eligible subjects were randomized to receive two sequential intramuscular injection of 0.5mg or 1.0mg M-001 (treatment), or two placebo (saline) injection, before receiving the sub optimal dose of H5N1 pandemic vaccine.

An open label, non-comparative bridging study to evaluate the safety of GCFLU® (seasonal influenza vaccine) administered intramuscularly in healthy Vietnamese volunteer aged from 3 years old

Children are particularly vulnerable to respiratory virus infections, especially influenza. Vitamin A & D deficiencies are associated with vulnerability to infectious diseases of the respiratory tract. The central hypothesis of this protocol is that vitamin supplements will enhance antibody responses toward the flu vaccine in children. Children, 2-8 years old, will be randomized to receive influenza virus vaccine with a vitamin A+D supplement or influenza virus vaccine with placebo. Children will be tested for vitamin levels and immune responses before and after influenza virus vaccinations to determine if vitamin supplementation improves the influenza virus vaccine-induced immune response. PRIMARY OBJECTIVE: To assess the vaccine-induced and total antibody (including IgG and IgA) response after influenza virus vaccine administration and IgA/IgG plus IgA/IgM ratios at 28 and 56 days in sera SECONDARY OBJECTIVE: To assess the neutralizing response toward influenza virus vaccine in the sera.

The objective of the present study is to evaluate the capability of the probiotic strain Lactobacillus coryniformis K8 CECT5711 (Lc K8) to enhance the immune response to influenza vaccine in elderly and the effect on respiratory symptoms related to respiratory infections. A randomized, double-blind, placebo-controlled trial was conducted between November of 2015 and April of 2016. A total of 98 residents of nursing homes aged more than 65 years were randomly assigned to receive Lc K8 or placebo for two weeks previous to influenza vaccination. Primary outcome was the percentage of seroconversion. Secondary outcome were the incidence of influenza-like illness and respiratory symptoms associated to respiratory infections during the follow-up period of 5 months. Serum cytokines and immunoglobulins levels were also evaluated.

This Phase 3/4, randomized, observer-blind, multi-center study, stratified study evaluated the immune (antibody) response, efficacy and safety of a cell-derived quadrivalent subunit influenza virus vaccine (Seqirus QIVc) in comparison with a non-influenza comparator, meningococcal serogroup A, C, W-135, and Y (Menveo®, GlaxoSmithKline Biologicals, S.A.) in healthy pediatric subjects ≥2 Years to <18 Years of Age

The purpose of the study was to evaluate efficacy of prophylactic Ingavirin intake by people having contact with sick people infected with influenza and other acute respiratory viral infections

The study will test whether a high dose influenza vaccination results in improved immunogenicity in adult SOT recipients as compared to standard vaccine. This will be a single center prospective observer-blind randomized controlled trial conducted at the Toronto General Hospital Multi-Organ Transplant Unit, University Health Network, Toronto, Ontario, Canada.

The purpose of the present study is to assess the immunogenicity, safety and reactogenicity of a two-dose schedule with vaccine GSK2340272A when co-administered with GSK Biologicals' Fluarix™ vaccine either at the time of first or second vaccination in elderly subjects aged 61 years and older.
