Filter by:A controlled, double-blind study to determine the immunogenicity and safety of influenza cell derived vaccine in elderly subjects.
The purpose of this study is to determine whether inactivated influenza vaccines are effective to protect school children and their households from getting influenza infection and further prevent student's absenteeism.
This study will evaluate the immunogenicity and safety of GSK Biologicals' Trivalent split virion influenza vaccine Fluviral for the 2008-2009 season in adults over the age of 18.
Vaccination is currently the most effective means of controlling influenza and preventing its complications and mortality in persons at risk. Once a year, a meeting of World Health Organization (WHO) experts takes place, leading to a recommendation on the influenza A and B strains that should be used for the production of vaccine for the coming influenza season. For the strains which do not change from the previous year, the vaccine can be formulated from the old mono bulk from the previous year. Bulks as old as 12 months may be blended to make trivalent inactivated vaccine (TIV) under the current Canadian and US licenses. This study is conducted to evaluate safety and immunogenicity of Fluviral vaccines made with the aged bulk material compared with the new bulk material. This protocol posting has been updated in order to comply with the FDA Amendment Act, Sept 2007.
The present study is designed to assess the lot-to-lot consistency of the immunogenicity of a GlaxoSmithKline Biologicals' pandemic influenza candidate vaccine (GSK1562902A) in adults aged between 18 and 60 years.
The aim of the study is to assess the safety & immunogenicity of a pandemic influenza vaccine administered at 2 different time points. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The purpose of this study is to test the specific humoral response after an intramuscular and intradermal influenza vaccination in lung transplant recipients
Influenza pandemics are caused by viruses that possess an Hemagglutinin molecule to which most of the population lacks immunity. If such virus is pathogenic to human and demonstrates the ability to transmit from person to person, the result is a global outbreak of disease that affects a high percentage of individuals in a short period of time and is likely to cause substantially increased mortality and morbidity in all countries of the world. Recently, purely avian influenza viruses, including the H5N1, H9N2 and H7N7 subtypes, have been directly transmitted to humans, raising concern over the possibility of a new influenza pandemic among the world's immunologically naive populations. In order to face this kind of situation, a pandemic influenza vaccine has to be developed.
Objectives: To determine whether people systematically misremember the “myths” (false information) as true, and to assess effects on perceptions of risk and behavioral intentions.
The study will be held in the winter of 2005-2007. The aim is to assess the effectiveness of the influenza vaccine in health care workers (HCW).
