Active clinical trials for "Influenza, Human"

Objective 1:To describe the safety of the inactivated, split-virion influenza vaccine, Northern Hemisphere (NH) 2007-2008 formulation. Objective 2: To describe the immunogenicity, of Fluzone, inactivated, split virion influenza vaccine NH 2007-2008 formulation. Objective 3: Serum Collection - To submit remaining available sera to Center for Biologics Evaluation and research (CBER) for further analysis by the Food and Drug Administration (FDA), the Center for Disease Control and Prevention (CDC), and the World Health Organization (WHO) to support selection and recommendation of antigen strains for subsequent influenza vaccines.

This 2 arm study will evaluate the efficacy and safety of oseltamivir in the seasonal prophylaxis of influenza in immunocompromised participants (as represented by transplant recipients). Transplant recipients enrolled when influenza is circulating in the community will be randomized to receive oseltamivir syrup or capsules 30 milligrams (mg) to 75 mg daily (depending on body weight) or placebo for 12 weeks. Influenza symptoms and safety data will be recorded throughout the study.

Pharmaceutical interventions, particularly vaccination, have been the principal public health method of preventing and controlling seasonal influenza. Other less invasive non-pharmaceutical interventions include the use of face masks and hand hygiene. In Asia, masks are used extensively, especially in Japan, but with only circumstantial evidence of efficacy. Although there are numerous studies that support hand hygiene as an effective measure for decreasing transmission of enteric infections, there are fewer data assessing the effect of hand hygiene on respiratory illnesses. Therefore it is proposed that a study be conducted on the use of face masks with and without the use of hand hygiene in comparison to no intervention in residence housing units of the University of Michigan. The interventions will be carried out during a period of influenza transmission that is defined by surveillance conducted at the University Health Service. Data will be collected on use of the interventions and the occurrence of influenza and other illnesses. When illness occurs meeting a case definition, specimens for viral isolation will be collected in all intervention settings. Face masks could theoretically lead to a large reduction in transmission frequency of influenza, especially if most transmission occurs by the airborne (large or small droplet) route. Even a modest reduction could have a major effect during an influenza pandemic.

Influenza (flu) viruses change continuously, therefore also the parts of viruses used in influenza vaccines can vary from year to year. In Europe, manufacturers/marketing holders of these vaccines are required to be involved in ongoing clinical trials and to present the results to the competent authorities each year. The current study is a phase IIIa clinical trial with a commercially available vaccine (Influvac®) supplied in pre filled syringes. It is part of the ongoing clinical trial program for Influvac® and will be done to assess the immunogenicity and safety and tolerability of next season's trivalent influenza subunit vaccine in two groups of healthy subjects: subjects aged >= 18 and <= 60 years and subjects >= 61 years of age (elderly).

This phase II, open label, is designed as a seasonal study to support annual strain update evaluating the safety, clinical tolerability and immunogenicity of the 2007-2008 formulation of Novartis Vaccines' adjuvanted, subunit influenza vaccine in adults with underlying chronic diseases

The objectives of this study are to assess the immune response as well as the safety and tolerability of an H5N1 influenza vaccine in an adult and elderly population. Further, the study will assess the need for a booster vaccination and whether a 6-month booster or a 12-month booster is more appropriate. An independent data safety monitoring board will review and evaluate the safety data obtained in this study on an ongoing basis.

The present study is designed to evaluate the immunogenicity and safety of a single or double dose of the pandemic influenza candidate vaccine (GSK1562902A), administered following a two-administration schedule (21 days apart) in adults over 60 years of age. The persistence of influenza antibodies will also be evaluated 24 months after vaccination.

The purpose of this study is to understand the spread of influenza (flu) in schools and households with elementary (K-5) school children, and develop ways to reduce the flu using non-pharmaceutical means.

The purpose of this Phase 3, observer-blind, placebo-controlled, multi-center study is to characterize the immunogenicity & safety of the investigation vaccination regimen of GSK 1557484A vaccine given to adults aged ≥18 years.

Pomegranate has a long history of use in folk medicine. There is vast data on the health benefits of pomegranate fruit and juice. Multiple studies have established the strong antioxidative effects of pomegranate polyphenols (primarily the ellagitannin punicalagin) and their health effects. A vast number of animal and human clinical studies have provided evidence on effect of pomegranate products on improving blood lipid profile, reducing blood pressure, improving endothelial function, anti-tumor activity, and its anti-atherosclerotic activity. We studied the protective effect of a pomegranate concentrate (POM Flu and Cold Formula®) in decreasing the incidence and duration of influenza-like illnesses and common cold among healthy adults.
