Filter by:Purpose: The study null hypothesis is that vitamin D supplementation will not influence time to acute respiratory tract infection in sheltered accommodation residents.
This is to evaluate immunogenicity based on EMEA/CHMP criteria, and safety & tolerability of cell-derived A/H1N1 influenza HA vaccine in healthy Japanese elderly subjects.
This is a Phase 2, randomized, double-blind, placebo-controlled multicenter study evaluating the efficacy and safety of two doses of favipiravir in adult patients with uncomplicated influenza.
The purpose of the study is to verify the safety and immunogenicity of a trivalent seasonal influenza vaccine with strain composition according to World Health Organization (WHO)/European Union (EU) recommendation for the 2009/2010 season.
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.
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
Unlike most influenza viruses, the 2009 H1N1 virus has affected people between 5 and 40 years old more often than people 60 years old or older. It may be that older people have had greater exposure to previous strains of H1N1 influenza, and this previous exposure protects them from infection. This study will examine how older people respond to a version of the H1N1 virus vaccine that includes a live, noninfectious version of the virus.
The purpose of this study is to assess the safety and immunogenicity of one dose of A/H1N1 non-adjuvanted pandemic vaccine to support registration of the vaccine in India. Primary Objective: - To describe the safety profile (injection site reactions and systemic events) of the vaccine within 21 days following vaccination, and serious adverse events throughout the study in all subjects Secondary Objectives: - To describe the immune response to the vaccine 21 days after vaccination by hemagglutination inhibition (HAI) testing in all subjects - To describe the antibody persistence 6 months after vaccination by HAI testing in all subjects.
Adult patients hospitalized with influenza have higher viral loads and more severe illnesses. Thus more aggressive treatment approaches (e.g. higher dose oseltamivir) have been suggested to treat patients suffering from severe influenza infection. The investigators plan to investigate the impact of higher-dose oseltamivir (150 mg b.d.) treatment on viral clearance and clinical recovery in adult patients hospitalized for severe influenza. Such information may lead to optimization of the management strategy used for these patients.
This randomized, open-label, multicenter phase 2 trial will assess the safety, efficacy, and pharmacokinetics (PK) of anti-influenza plasma in subjects with influenza A or B. Hospitalized subjects with influenza A or B that have either a low oxygen level or a high respiratory rate will be eligible for study participation. This study will enroll adults, children and pregnant women.
