Active clinical trials for "Influenza, Human"

To assess the tolerability and safety of a single injection of Influenza VLP Vaccine when administered intramuscularly (IM) at 15 µg and 60 µg HA per each strain. To assess the immunogenicity of Influenza VLP Vaccine administered at 15 µg and 60 µg HA per strain as measured by hemagglutination inhibition (HAI) antibody titers to each of the component viral strains [A/Brisbane/59/2007 (H1N1); A/Brisbane/10/2007 (H3N2) and B/Brisbane/60/2008].

This is a phase I/II, randomized, single-blind, placebo-controlled escalating double-dose study of the safety and priming potential of an intramuscular Influenza vaccine (Multimeric-001) injected to elderly volunteers.

The purpose of this study is to compare the safety and effectiveness (immune response) to one or two doses of adjuvanted H1N12009 influenza vaccine in young children. An adjuvant is an additive that can boost the immune response. The study will enroll 300 children (ages 6-35 months). Participants will receive 2 doses of adjuvanted H1N12009 vaccine 3 weeks apart. Study procedures include: medical history, blood samples and completing a memory aid. Participants will be involved in study related procedures for approximately 6 weeks.

The purpose of this study is to assess the safety and effectiveness (immune response) to a licensed H1N12009 influenza vaccine in aboriginal children and adults. The study will enroll 200 healthy adults (ages 20-59 years) and 75 healthy children (ages 6-35 months). Adults will receive one dose of a licensed H1N1 vaccine and children will receive two doses of a licensed H1N1 vaccine approximately 3 weeks apart. Study procedures include: medical history, blood samples and completing a memory aid. Participants will be involved in study related procedures for approximately 3 weeks (adults) or 6 weeks (children).

Patients treated with chemotherapy or immunosuppressives are at higher risk of influenza infection and mortality and morbidity are higher compared to healthy adults. Vaccination against the influenza virus can prevent these complications. In this study it is investigated whether vaccination during chemotherapy is effective in reaching protective serum antibody concentrations and the relation between time of vaccination (day 4 +/- 1 day versus day 16 +/- 1 day of the chemotherapy cycle).

The purpose of this study is to compare the safety and immunogenicity over a 9-month period of five different dosages of Ad4-H5-Vtn in volunteers (Vaccinees) who receive three doses of the study vaccine or placebo. In addition, transmission of Ad4-H5-Vtn will be evaluated in all Household Contacts residing with the vaccinated volunteers. Vaccinees also may participate in a substudy in which they receive a booster vaccination with the licensed Influenza Virus Vaccine, H5N1 (Sanofi Pasteur).

This trial will assess the immunogenicity and safety elicited by the adjuvanted GSK Biologicals' influenza investigational vaccine GSK2340274A in healthy Japanese adults aged 20-64 years.

A phase 3 study to obtain additional safety and immunogenicity data on Solvay's cell-derived seasonal trivalent subunit influenza vaccine in adult and elderly subjects without significant illnesses and to demonstrate consistency of the immunogenicity of the three lots of the same vaccine, comparison of cell-derived vaccine to Solvay's egg-derived vaccine including assessment of non-inferior immunogenicity

This study is in support of the annual application for the variation of the vaccine strains for a marketing authorisation. Objectives: To evaluate compliance, in terms of immunogenicity, of the corresponding strength of the intradermal (ID) influenza vaccine Northern Hemisphere (NH) 2009-2010 formulation. To describe the safety of the corresponding strength of the ID influenza vaccine, NH 2009-2010 formulation.

This present study, randomized, single-blind, dose-ranging, multicenter study, will evaluate immunogenicity, safety and tolerability of two doses of an adjuvanted and not-adjuvanted new swine-origin influenza A/H1N1 virus monovalent subunit vaccine in healthy adult and elderly subjects. A booster dose will be administered 12 months after the first vaccination.
