Filter by:The World Health Organisation has warned that an influenza pandemic is inevitable. The avian influenza strain H5N1 is one of the leading candidates to cause the next influenza pandemic. Children are likely to be a special target group for vaccination; therefore, this study will test the safety and immunogenicity of an H5N1 pandemic influenza vaccine in healthy children.
The purpose of this study is to demonstrate the efficacy of GSK Biologicals' influenza vaccine (Fluarix™) administered intramuscularly in adults.
The purpose of this study is to evaluate the immunogenicity and the safety of the candidate vaccine compared to Fluarix™ administered intramuscularly in elderly aged 60 years and above
Based on pre-clinical trial data and principle of GCP, the objective of phase I clinical trial is to evaluate safety and immunogenicity of Pan-flu vaccine, an inactivated whole virion H5N1 vaccine with aluminium hydroxide adjuvant.
Due to antigenic changes of influenza viruses, the virus strains used in influenza vaccines are adjusted every year according to WHO (World Health Organization) and CHMP (Committee for Medicinal Products for Human Use) recommendations. Immunogenicity and tolerability of the newly composed vaccines are subject for evaluation in a yearly clinical trial in non-elderly and elderly subjects (CPMP/BWP/214/96).
The objective of this study is to assess the safety and immunogenicity of 4 different doses of adjuvanted and non-adjuvanted mock-up pandemic influenza vaccine. Subjects will be enrolled sequentially into 3 study cohorts with 4 escalating doses of H5N1 hemagglutininin antigen (3.75 µg adjuvanted, 7.5 µg adjuvanted/non-adjuvanted, 15 µg adjuvanted/non-adjuvanted, 30 µg adjuvanted). Starting with the lowest dose level, subjects will receive 2 vaccinations (21 days apart) at the dose to which they were assigned. Subjects will be monitored for safety and for antibody response to the vaccine. A data safety monitoring board will review and evaluate all the safety data obtained for a dose level before allowing administration of the next (higher) dose.
The purpose of this study is to evaluate how effective the vaccine is at preventing subjects developing flu symptoms after they are directly exposed to flu virus. The study will also evaluate how well the vaccine is tolerated at sites where administrations are given, any effects it may have on subjects' wellbeing and whether it can produce antibody responses in the body
This is a study to compare the safety and immune response of a pentavalent DTaP-HB-PRP~T combined vaccine with Tritanrix-HepB/Hib™, when both are given concomitantly with OPV at 6, 10, and 14 weeks of age.
Avian influenza (AI), or bird flu, has recently become a major health concern in Asia and other parts of the world. The need for a vaccine to prevent the spread of AI among livestock and to humans is sorely needed. The purpose of this study is to test the safety of and immune response to a new AI vaccine in healthy adults.
Vaccination is currently the most effective mean of controlling influenza and preventing its complications and mortality in persons at risk. Because of the variable nature of influenza viruses, the composition of influenza vaccines changes almost every year, to target the 3 main circulating strains. Each year the influenza vaccine formulation may thus be different and clinical studies are mandated to ensure that the immunogenicity and safety of the vaccine formulated from the three annual circulating strains are similar to what was observed during the previous years. This study is designed to test the immunogenicity and reactogenicity of the Fluarix™ vaccine containing the influenza strains recommended for the 2006-2007 season.
