11 Clinical Trials for Various Conditions
This study will evaluate the immunogenicity and safety of inactivated H1N1 swine-origin monovalent influenza vaccine in immunocompromised children and young adults.
The purpose of this study is to evaluate specific approaches used to prevent/reduce influenza transmission in the SCI/D System of Care in response to the 2009 H1N1 pandemic, including assessing infection control strategies used by SCI staff and guidance provided by local infection control units. Due to the rapid spread of and uncertainties about the H1N1 virus, we will evaluate patient's beliefs, behaviors, and information seeking strategies (e.g., social media). These findings will lend to the understanding of ways to handle emergent issues, such as the H1N1 pandemic, in special populations.
The purpose of the study is to evaluate different doses of the Influenza A/H1N1 pandemic vaccine in adults and the elderly. Primary Objectives: * To describe the immunogenicity of the candidate vaccines after a single injection. * To describe the safety of the candidate vaccines after a single injection.
The purpose of the study is to evaluate different doses of the Influenza A/H1N1 pandemic vaccine. Primary Objectives: * To describe the immunogenicity of the candidate vaccines after each injection. * To describe the safety of the candidate vaccines after each injection.
The purpose of the study is to evaluate different doses of the Influenza A/H1N1 pandemic vaccine in toddlers and children. Primary Objectives: * To describe the immunogenicity of the candidate vaccines after each injection. * To describe the safety of the candidate vaccines after each injection.
The purpose of this study is to test the safety and efficacy of zanamivir given intravenously and how well it works at two different doses in hospitalized adolescents and adults with flu. Zanamivir will be compared with oseltamivir, which is used for treating flu.
This study is designed to characterize the safety and immunogenicity of a' pandemic influenza (H1N1) candidate vaccine GSK2340274A in adults 19 to 40 years who have never received influenza vaccination.
The purpose of this study is to determine whether zanamivir aqueous solution given by intravenous injection is safe in treating hospitalized patients with confirmed influenza infection. A single arm open-label design has been selected to achieve the primary objective of providing regulatory authorities with safety data on IV zanamivir.
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.
Despite widespread use of respiratory protective equipment in the U.S. healthcare workplace, there is very little clinical evidence that respirators prevent healthcare personnel (HCP) from airborne infectious diseases. Scientific investigation of this issue has been quite complicated, primarily because the use of respirators has become "the standard of care" for protection against airborne diseases in some instances, even without sufficient evidence to support their use. The key question remains: How well do respirators prevent airborne infectious diseases? The answer to this important question has important medical, public health, political and economic implications.
The purpose of this study is to compare the safety and tolerability of Zanamivir using a Rotahaler device presentation to placebo within the Rotahaler presentation and to the Diskhaler device.
