Medical and Biotech [MESH] Definitions
Influenza In Birds
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.
Influenza B Virus
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.
Hemagglutinin Glycoproteins, Influenza Virus
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.

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...
Respiratory infections caused by influenza viruses spread rapidly, resulting in significant annual morbidity and mortality worldwide. Currently, the most effective public health measure against infect...
SUMMARYThe effectiveness of influenza vaccination programmes is seldom known during an epidemic. We developed an internet-based system to record influenza-like symptoms and response to infection in a...
SUMMARYAn analysis was undertaken to measure age-specific vaccine effectiveness (VE) of 2010/11 trivalent seasonal influenza vaccine (TIV) and monovalent 2009 pandemic influenza vaccine (PIV) administ...
During the 2011-12 influenza season in the United States, influenza activity* occurred at low levels during October through December and increased in January and February before peaking in mid-March....
Trivalent seasonal influenza vaccines contain 2 A strains and 1 B strain. B strains of 2 antigenically distinct lineages, Yamagata and Victoria, have been co-circulating annually, and the B strain inc...
