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 influenz...
The primary purpose of the study is to assess the equivalence of the immune response elicited by two GSK Biologicals' adjuvanted influenza investigational vaccines (GSK2340272A and GSK2340...
This study is designed to characterize the safety and immunogenicity of a' pandemic influenza (H1N1) candidate vaccine GSK2340274A in adults 18 to 64 years of age.
The objective of this study is to evaluate the immunogenicity and safety of GSK Biologicals' investigational influenza vaccine GSK2340274A following one dose and following a second dose, u...
The purpose of this study is to show that vaccination with a single dose of GSK Biologicals' pandemic H1N1 vaccine results in an immune response that meets or exceeds European Medicines Ag...
The effectiveness of currently licensed vaccines against influenza has not been clearly established, especially among individuals at increased risk for complications from influenza. We used a test-neg...
SUMMARY A hypothetical influenza infection-induced non-specific immunity may reduce the risk of subsequent non-influenza respiratory virus (NIRV) infection and bias the influenza vaccine effectiveness...
The goal of the influenza vaccine is to prevent influenzaInfluenza virus infection and control the yearly seasonal epidemic and pandemic. However, the presently available parenteral influenza vaccine ...
Influenza CD8(+) T-cell epitopes are conserved amongst influenza strains and can be recognized by influenza-specific cytotoxic T-cells (CTLs), which can rapidly clear infected cells. An influenza pept...
The need to respond quickly to potential influenza pandemics is important. Immunologic priming (initial presentation of an antigen to allow antibody responses on revaccination) with vaccine directed t...
Medical and Biotech [MESH] Definitions
Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.
Vaccines used to prevent infection by viruses in the family ORTHOMYXOVIRIDAE. It includes both killed or attenuated vaccines. The composition of the vaccines is changed each year in response to antigenic shifts and changes in prevalence of influenza virus strains. The vaccine is usually bivalent or trivalent, containing one or two INFLUENZAVIRUS A strains and one INFLUENZAVIRUS B strain.
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
A genus of the family ORTHOMYXOVIRIDAE comprising viruses similar to types A and B but less common, more stable, more homogeneous, and lacking the neuraminidase protein. They have not been associated with epidemics but may cause mild influenza. Influenza C virus is the type species.
