Active clinical trials for "Influenza, Human"

This study will evaluate the safety of an influenza (flu) vaccine in Korean men and women aged 65 years and older.

This study is designed to characterize the safety and immunogenicity of pandemic influenza (H1N1) candidate vaccines GSK2340274A and GSK234072A in children 3 to less than 10 years old.

This study is designed to test the immunogenicity and reactogenicity of the Fluarix™/Influsplit SSW® influenza vaccine containing the influenza strains recommended for the 2010-2011 season.

DNA vaccines consist of small pieces of DNA also known as plasmids, and have several potential advantages over traditional vaccines. Thus far, DNA vaccines appear to be well tolerated in humans. The investigators have developed a DNA vaccine, VGX-3400X, which includes plasmids targeting the proteins of the H5N1 avian influenza virus. The vaccine will be delivered via electroporation (EP) which uses the CELLECTRA constant current device to deliver a small electric charge following injection, since animal studies have shown that this delivery method increases the immune response to vaccine. The vaccine will be given to 30 healthy adult subjects. It is hypothesized that VGX-3400X + EP will be well tolerated and immunogenic.

The purpose of this study is to evaluate the possibility that giving an increased dose of flu vaccine to children 6 through 35 months of age will improve protection against influenza without increasing side effects. Investigators will evaluate the body's response to the vaccine. Male and female participants' ages 6-35 months, who have never received flu vaccine, and those ages 12-35 months, who have been previously vaccinated, will participate in the study for about 7 months. Vaccine naïve study participants will receive two doses of flu vaccine, either the 0.25 mL dose (Group 1) or 0.5 mL dose (Group 2). Previously vaccinated subjects will receive one dose of flu vaccine, either the 0.25 mL dose (Group 1) or 0.5 mL dose (Group 2). Study procedures include physical examination, memory aids, blood sampling and a follow-up phone call about 6 months after the last vaccine dose.

This study is designed to assess the immunogenicity, reactogenicity and safety following vaccination with GSK Biologicals' FluarixTM vaccine in children who have previously been vaccinated with one dose of PandemrixTM at the age of 10-17 years.

This study is designed to test the safety and immunogenicity of Fluviral® (2010 - 2011 Season) in adults aged 18 to 60 years and over 60 years.

This study is designed to test the immunogenicity and safety of an investigational influenza vaccine, in adults compared to two other influenza vaccines. This study will also evaluate the lot-to-lot consistency of three vaccine lots.

This trial will assess the immunogenicity and safety elicited by the adjuvanted GSK Biologicals' (pre-) pandemic influenza candidate vaccine in healthy Japanese adults.

The purpose of this study is to determine whether probiotic treatment improves the protection against respiratory infections after influenza vaccination in elderly living in nursing homes.
