Filter by:This phase III is designed to confirm the previous trial results evaluating the safety, clinical tolerability and immunogenicity of the 2006-2007 formulation of Novartis Vaccines' adjuvanted influenza vaccine and subunit influenza vaccine in adults with underlying chronic diseases.
To evaluate the antibody response to each influenza vaccine antigen when administering a single dose to subjects aged > 18 years
Due to antigenic changes of influenza viruses, the virus strains used in influenza vaccines are adjusted every year according to WHO and CPMP recommendations. Immunogenicity and tolerability of the newly composed vaccines are subject for evaluation in a yearly clinical trial in non-elderly adults and elderly subjects (CPMP/BWP/214/96).
The objectives of this Phase I/II study are to assess the safety and immunogenicity of two different dose levels of a non-adjuvanted H5N1 influenza vaccine in a healthy young adult population. Subjects will be randomized 1:1 to receive two intramuscular injections (21 days apart) of the vaccine containing either 3.75 µg or 7.5 µg H5N1 hemagglutinin (HA) antigen in a non-adjuvanted formulation. Subjects will be monitored for safety and for antibody response to the vaccine. A data safety monitoring board will review the safety data after the first and second vaccination.
Annual trial for registration of sub-unit influenza vaccine produced in mammalian cell culture, using the strain composition 2007/2008, when administered to adult and elderly subjects
The purpose of this study is to evaluate the safety and immune response of two-doses of GSK Biologicals' candidate influenza vaccine GSK 1557484A with or without adjuvant in adults. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
The present study is designed to evaluate the reactogenicity and immunogenicity of one or two booster administrations of an influenza pandemic candidate vaccine (GSK1562902A) in adults aged between 19 and 61 years, previously vaccinated with 2 doses of a pandemic candidate vaccine. Fifty new subjects who did not participate in a primary study (106750, NCT00309634) will be recruited. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT00309634)
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 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. This study is designed to test the safety/reactogenicity and the immunogenicity of the Fluviral Trivalent Split Virion Influenza Vaccine containing the influenza strains recommended for the 2007-2008 season.
This randomized trial compared the immunogenicity of 60% dose intradermal (ID) influenza vaccination to standard intramuscular (IM) vaccination of full-dose or 60% dose vaccine. Pre- and postvaccination measurements in the hemagglutination inhibition antibody (HAI) titer were compared. Participants who received reduced-dose vaccine were revaccinated with full-dose IM vaccine.
The present study is designed to evaluate in children (aged between 3 and 9 years) the immunogenicity and safety of different antigen doses of the candidate vaccine (GSK1562902A) administered following a two-administration schedule (21 days apart). Subjects in the control group will receive Fluarix. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
