Filter by:The purpose of this study is to describe the immune response to a novel H1N1 influenza vaccination in healthy adults, and to understand the factors that allow healthy adults to respond to a single dose of vaccine even if they have never previously experience novel H1N1 disease or vaccination.
Recently, the emergence and rapid global dissemination of novel swine-origin influenza A virus (H1N1) with unique epidemiologic characteristics has heightened awareness and concern of this viral pathogen, and its potential for major disruption of both civil and military stability. Although advances in medical and scientific technologies have improved our basic understanding of respiratory disease, many questions about the epidemiology and immunology of ARI remain unanswered. This study plans to initiate a multi-site, multi-disciplinary research collaboration, termed the Acute Respiratory Infection Consortium (ARIC) for the purpose of studying the etiology, epidemiology and immunology of influenza-like illness (ILI) in order to describe the natural history and risk factors for disease, as well as the characteristics of the host immune response. At the core of the ARIC is the proposed observational, longitudinal study of the Natural History Study of ILI among active duty military members, healthy retirees, and their dependents recruited from both inpatient and outpatient settings of military treatment facilities (MTF) in the continental US to be followed for a total of four (4) visits over a 28-day period. Additionally, the investigators also propose to conduct a household-based study of influenza (Family Transmission Study) in which individuals who have a laboratory-confirmed influenza illness will be recruited and enrolled along with their family members for the purpose of studying transmission of influenza within households. Taken together, these studies will establish a longitudinal cohort of ILI among active duty members and their families, as well as a repository of biological specimens relevant to the epidemiology and immunology of infection. Ultimately, these studies will serve as a solid foundation on which future investigations of ARI epidemiology, treatment and prevention can be based.
- 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].
The objective of this study is to evaluate the safety and immunogenicity study of GSK Biologicals' pandemic influenza candidate vaccine (GSK2340272A) in children aged 3 to 9 years.
The purpose of this study is to generate additional data on the immunogenicity and safety of revaccination with Fluzone Intradermal (ID) or Fluzone Intramuscular (IM) vaccine. Primary Objective: - To evaluate and describe the safety profile of revaccination with Fluzone ID for all participants. Secondary Objective: - To describe immunogenicity following revaccination with Fluzone ID or Fluzone IM.
To determine the tolerability and immunogenicity of FLUVAL P monovalent influenza vaccine in adults and elderly people, with the objective to verify efficacy and tolerability of the study drug.
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.
This study is designed to characterize the safety and immunogenicity of a' pandemic influenza (H1N1) candidate vaccine GSK2340274A in adults 18 to 64 years of age.
A single center, randomized clinical trial is to be conducted in healthy adults (18-60 years) to evaluate the safety and immunogenicity and study the cell-mediated Immunity of Sinovac's H1N1 influenza A Vaccine (PANFLU.1) with Trivalent Inactivated Influenza Vaccine (ANFLU).
This is a laboratory-blinded study in healthy toddlers, children, and teenagers designed to investigate the safety, reactogenicity, and immunogenicity of an inactivated influenza H1N1 vaccine (AdimFlu-S). There are 3 age strata, and each contains at least 50 subjects: greater than or equal to 1 year to less than 3 years, greater than or equal to 3 years to less than 6 years, and greater than or equal to 6 years to less than 18 years. In each age strata, all eligible subjects received 2 injections of AdimFlu-S (A/H1N1) at a designated dosage level (7.5 μg, 15 μg and 15 μg for 1~<3, 3~<6 and 6~<18 years, respectively) at 3 weeks apart. Following immunization, safety is measured by assessment of adverse events for 6 weeks following the first vaccination, serious adverse events and new-onset chronic medical conditions through 7 months post first vaccination, and reactogenicity to the vaccines for 7 days following each vaccination. Immunogenicity testing includes hemagglutination inhibition (HAI) testing on serum obtained before first vaccination, and three and six weeks after first vaccination.
