The World Health Organisation has warned that an influenza pandemic is inevitable. The avian influenza H5N1 virus strain is the leading candidate to cause the next influenza pandemic. This study will test the safety and immunogenicity of a H5N1 Pandemic Influenza Vaccine in healthy adults. The Study will also assess Lot to Lot consistency of the Pandemic Influenza Vaccine.
This is a study to assess the immune (antibody) response and safety of a bioCSL split virion, inactivated quadrivalent influenza vaccine, in comparison with a US licensed 2014/2015 trivalent influenza vaccine (CSL TIV-1), and a trivalent influenza vaccine containing the alternate B strain (CSL TIV-2), in healthy adult volunteers aged 18 years and above.
This phase 3 study is designed 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 three different manufactured lots of the same vaccine.
The purpose of this study is to evaluate the body's immune response at different time points to an FDA-approved seasonal influenza vaccine. By better understanding the way the immune system responds to the influenza vaccine, the investigators can design more effective vaccines against influenza.
The aims of this study are: 1. to investigate if HIV infection alters the antibody responses to influenza and 2. to assess the ability of licensed influenza vaccine to induce functional non-neutralising antibodies in HIV-infected and HIV-uninfected subjects.
This study is powered to prospectively evaluate the relative effectiveness of adjuvanted trivalent influenza vaccine (aTIV; FLUAD) in preventing influenza mortality, hospitalization, and functional decline in a nursing home population in the U.S., compared to the commercially available, standard dose trivalent seasonal influenza vaccine (TIV; Fluvirin).
The study described here will immunize children with trivalent influenza vaccine (TIV) and determine whether this reduces influenza illness among the immunized children and their older family members. The comparison or control group for the children receiving influenza vaccine will be children immunized with inactivated poliovirus vaccine (IPV). The study will also provide information on the amount of disease produced by influenza in the study population.
To evaluate the safety and immunogenicity of the three consecutive lots of an seasonal split influenza vaccine Anflu in adults, a randomized, double-blind and controlled clinical trial was conducted in 560 subjects in Tianjin City of China.
Following the licensure of sanofi pasteur's 90 µg rgA/Vietnam/1203/2004 pandemic influenza vaccine, efforts to develop a lower antigen dose formulation with improved immunogenicity using adjuvants were initiated. The present study is part of this endeavor. It is primarily a formulation/dose-finding study with a secondary aim at generating safety and immunogenicity data for the final formulation for the development of a pre-pandemic vaccine.
The aim of this study is to assess the immunogenicity and safety of a quadrivalent influenza vaccine compared with a trivalent influenza vaccine in participants aged above 3 years.
Influenza is associated with significant morbidity and mortality in solid-organ transplant (SOT) recipients and it is mainly prevented by seasonal influenza vaccination. Unfortunately, the immunogenicity of standard influenza vaccine is suboptimal in this population. Vaccination with a high-dose (HD) influenza vaccine or an MF59-adjuvanted (MF59a) vaccine have significantly reduced the incidence of influenza and increased the immunogenicity of influenza vaccine in the elderly. ...
The World Health Organisation has warned that an influenza pandemic is inevitable. The avian influenza H5N1 virus strain is the leading candidate to cause the next avian influenza pandemic. This study will test the safety and immunogenicity of a H5N1 pandemic influenza vaccine in healthy adults.
Since influenza vaccines are normally administered every year because of the frequent change in their antigenic composition, the safety and immunogenicity profile of adjuvanted influenza vaccine need to be re-evaluated after repeated vaccine administration. In this study, subjects previously vaccinated with Fluarix or the influenza adjuvanted vaccine, will receive a booster dose with the 2006-2007 season's formulations of either Fluarix or the adjuvanted vaccine.
The purpose of this research is to demonstrate immunologic equivalence of three consecutive production lots of the subunit influenza vaccine compared to egg-derived inactivated influenza vaccine in healthy subjects 18 to 49 years of ages. In addition, this study is to show how safe and well tolerated a conventional inactivated subunit influenza vaccine, licensed in many countries outside the United States, is compared to an inactivated influenza vaccine, licensed in the United...
Evaluate the immune response and reactogenicity of H5N1 vaccination in adults aged 18 years and above (as part of a tetravalent vaccine)
The goal of this study is to determine whether Fluviral, an inactivated, injectable trivalent influenza vaccine (flu shot) is effective in preventing respiratory illnesses that are severe enough to limit normal daily activities and that are shown by virus culture to be caused by influenza viruses. The study will also examine the safety of the vaccine and collect measurements of the immune system responses produced by the vaccine.
The World Health Organisation has warned that an influenza pandemic is inevitable. The avian influenza strain H5N1 is one of the leading candidates to cause the next influenza pandemic. Children are likely to be a special target group for vaccination; therefore, this study will test the safety and immunogenicity of an H5N1 pandemic influenza vaccine in healthy children.
The World Health Organisation has warned that an influenza pandemic is inevitable. The avian influenza H5N1 virus strain is one of the leading candidates to cause the next influenza pandemic. The elderly are likely to be a special target group for vaccination; therefore, this study will test the safety and immunogenicity of a H5N1 pandemic influenza vaccine in a healthy elderly population.
Safety, Tolerability, and Immunogenicity of Different Combinations of Trivalent Influenza Vaccine Varying Influenza Antigen Dose, Adjuvant Dose, and Route of Administration in Healthy Elderly Individuals Ages 65 Years and Older
The study will evaluate the safety, tolerability and immunogenicity of different doses and types of Influenza Vaccine in healthy elderly subjects.
The purpose of this study is to compare the antibody response and reaction rates in children age 6-23 months when they are given either the currently recommended schedule of two 0.25ml doses of influenza vaccine one month apart or two 0.5ml doses of influenza vaccine, one month apart.
The purpose of this trial is to assess the knowledge and attitudes of post-partum women regarding influenza and the use of the influenza vaccine in pregnancy.
This is a complimentary study to an elderly influenza study. Subjects 18-40 will receive a single dose flu vaccine and be evaluated for humoral and cell mediated immunity to influenza antigens.
The purpose of this study is to evaluate the safety and immunogenicity of quadrivalent influenza vaccine in healthy children aged 6-35 months.
Multicentric study, Phase III; this study is a randomized, participant- and observer-blind, parallel group evaluation to evaluate the immunogenicity, relative efficacy, safety and reactogenicity of a recombinant quadrivalent hemagglutinin influenza vaccine versus an inactivated quadrivalent influenza vaccine in pediatric subjects and adolescents of 3-17 years of age. Investigational vaccine is indicated for active immunization against influenza A and B for strains contained in ...
A multi-centre, randomized, placebo controlled, trial. Participants at high-risk for vascular events from the network of INTER- CHF will be randomized to inactivated influenza vaccine or placebo and followed prospectively over three influenza seasons. 3,500 participants will be enrolled prior to influenza season, randomized to either influenza vaccine or saline placebo, either of which they will receive annually for three years and then followed over each of the influenza seaso...
