Medical and Biotech [MESH] Definitions
Influenza A Virus, H1n1 Subtype
A subtype of INFLUENZA A VIRUS comprised of the surface proteins hemagglutinin 1 and neuraminidase 1. The H1N1 subtype was responsible for the Spanish flu pandemic of 1918.
Orphan Drug Production
Production of drugs or biologicals which are unlikely to be manufactured by private industry unless special incentives are provided by others.
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.
A combined vaccine used to prevent infection with diphtheria and tetanus toxoid. This is used in place of DTP vaccine (DIPHTHERIA-TETANUS-PERTUSSIS VACCINE) when PERTUSSIS VACCINE is contraindicated.
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.
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...

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.
This trial will assess the immunogenicity and safety elicited by the adjuvanted GSK Biologicals' influenza investigational vaccine GSK2340274A in healthy Japanese adults aged 20-64 years.
The purpose of this study is to characterize the safety and efficacy of GSK Biologicals' H1N1 flu candidate vaccines GSK2346274A and GSK2340273A in children 6 months to less than 10 years...
Annually adjusted inactivated influenza vaccines can prevent infection and limit the spread of seasonal influenza when vaccine strain closely matches circulating strain. For the years when the match i...
Systemic onset juvenile idiopathic arthritis (SoJIA) remains difficult to treat. In addition to conventional antirheumatic therapy with non-steroidal antirheumatic drugs (NSARDs), steroids or disease-...
During the 2009-2010 A/H1N1 influenza pandemic, pregnant women infected with the virus experienced excess morbidity and mortality when compared with other groups. Once a vaccine was available, pregnan...
Vaccination with the non-adjuvanted split-virion A/California/7/2009 influenza vaccine (pandemic H1N1 2009 vaccine) began in October 2009 in Japan. We studied how prior vaccination with a seasonal tri...
A pooled analysis of data from four vaccination studies conducted in Europe was undertaken to assess the immunogenicity of Infanrix™ hexa (DTPa-HBV-IPV/Hib, GlaxoSmithKline Biologicals) when adminis...
