12 Clinical Trials for Various Conditions
The demographic characteristics, clinical features, course, and outcomes of severe H1N1 influenza infection requiring intensive care have not been defined rigorously and systematically. While the majority of patients in early reports of critically ill novel influenza A (H1N1) have respiratory involvement, up to 10-20% may present with non-respiratory organ failures, such as shock, seizures, or acute renal failure. The burden of disease and resource utilization of these patients remains largely unknown. The purpose of this surveillance registry is to characterize the demographics, clinical features, outcomes, and resource utilization of patients with H1N1 influenza infection who require intensive care.
This is study where medical record information will be collected as well as collection of excess biological samples.
The purpose of this research study is to collect information on problems that patients with the novel H1N1 influenza and/or the seasonal influenza experience. Novel H1N1 flu is also called the swine flu. Seasonal influenza is also called the regular flu. The purpose of this study is to collect information from patients who are infected with either the novel H1N1 or the seasonal flu and to determine what makes patients critically ill with these infections. The goal is to develop a registry that will aid investigators in determining specific markers that lead to development of severe illness in these infections.
Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to describe participants seeking medical care in geographically diverse locations with 2009 H1N1 infection and their clinical course over a 14-day period following enrollment. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. This version of the protocol further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded
The purpose of this study is to test an investigational vaccine known as "VAX161C." An "investigational" vaccine is one that is not licensed for commercial use in the by the United States (US) by the US Food and Drug Administration (FDA). VAX161C is a vaccine for the influenza A virus subtype H5N1 avian influenza virus (bird flu). In this study, the subject will receive the VAX161C vaccine at one of six doses to see which dose is the best. VaxInnate wants to find out how safe these doses of vaccines are and how well they are tolerated by people who receive them. To measure how effective each type of the vaccine is, VaxInnate will test the ability of the body to develop an immune response, which means how the body recognizes and defends itself against the influenza virus.
This study will evaluate the safety and immunogenicity of VAX161B \[STF2.HA5 H5N1\], a recombinant, inactivated, subunit influenza vaccine given as a two dose regimen at a range of doses.
This is a multicenter, escalating dose-ranging study to assess the safety, reactogenicity and immunogenicity of 3 different novel H1N1 influenza vaccine constructs delivered i.m. as a single dose vaccination on day 0.
The purpose of this study is to determine differences between the immune responses in healthy and depressed people. Participants will receive the influenza vaccine and their responses will be monitored. This study will recruit 15 healthy and 60 depressed participants.
Background: * Vaccines are substances used to try to create resistance (or immunity) to a disease and to prevent an infection. Researchers are testing a new DNA vaccine designed for a new type of influenza, often referred to as swine flu. The DNA vaccine will instruct the body to make a particular kind of influenza protein that the immune system will be able to recognize. * Researchers are interested in determining if the vaccine is safe and effective in humans, and would like to study the immune system's response to the vaccine. The vaccine will not give participants influenza; however, it may not be effective in preventing them from getting influenza at a later date. Objectives: * To evaluate the safety and tolerability of the VRC-FLUDNA057-00-VP influenza vaccine as administered to healthy adults. * To evaluate antibody responses to the new influenza vaccine. Eligibility: - Healthy adults between the ages of 18 and 70. Design: * Participants will have seven planned clinic visits during this study (enrollment day and study weeks 1, 4, 8, 9, 12, and 32). * All participants will receive three injections of the test vaccine, given as individual doses on day 0, day 28, and day 56 of the study. The vaccine will be given in the upper arm muscle. * Injections will be given using a needleless system that delivers the vaccine through the skin by using the pressure of carbon dioxide to inject the vaccine through the skin and into the muscle. Participants will remain at the National Institutes of Health (NIH) Clinical Center for at least 30 minutes after the injection to be monitored for any reaction. * Participants will be asked to keep a 7-day diary card after each injection to record their physical reactions to the vaccine. * Participants will be asked to return to the NIH Clinical Center as requested by researchers for additional blood tests and other procedures, as required by the study.
This study is designed to evaluate the safety, tolerability, and immune response of LIQ001 mixed with a commercially available seasonal influenza vaccine (Fluzone) in two populations of subjects; healthy adult subjects 18 to 49 years of age and healthy elderly subjects 65 years of age or older.
The purpose of this research is to determine the effectiveness of the novel H1Nl influenza (inactivated/killed formulation) vaccine among both HIV-infected and HIV-uninfected persons. The administration of the H1Nl vaccination is not part of the study's procedures, but is being given as part of routine care.
Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.
