Active clinical trials for "Influenza, Human"

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).

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.

The purpose of this study is to characterize the safety and immune response of the H1N1 (swine) flu vaccines GSK2340274A and GSK2340273A in children 6 months to less than 9 years of age. This Protocol Posting has been updated following the Protocol amendment 1 & 2, September and October 2009. The sections impacted are study design, objectives and analysis methods.

The goal of this clinical study is to learn if Pegasys (pegylated interferon) or Roferon (interferon) can make the Trivalent Inactivated Influenza vaccine (TIV) more effective in increasing the body's immune reaction against the flu virus in patients with Chronic Lymphocytic Leukemia (CLL).

The objective of the study is to evaluate the immunogenicity and safety of GSK Biologicals' investigational vaccine GSK2340272A.

The purpose of this study is to determine whether CSL425 is a safe and effective vaccine for eliciting an immune response to H1N1 influenza in healthy adults

The purpose of the study is to obtain immunogenicity and safety data at different dose levels of an investigational H1N1 pandemic influenza vaccine in healthy adults 18 years of age and older.

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 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).
