(CIDRAP News) Live-virus vaccines made from a combination of H5N1 avian influenza virus and another flu strain protected laboratory mice and ferrets from deadly infection with several different H5N1 strains, according to a report published yesterday.
(CIDRAP News) A controlled study of H5N1 influenza patients in Vietnam has provided fresh evidence that explosive viral growth and the resulting cytokine storm, or excessive immune response, account for the often lethal nature of H5N1 disease.
Sept 7, 2006 (CIDRAP News) In a human trial in China, a whole-virus H5N1 avian influenza vaccine generated an immune response with a relatively low dose of antigen, suggesting that it could be used to immunize more people than may be possible with some other vaccines under development.
(CIDRAP News) No highly pathogenic H5N1 avian influenza virus has turned up in any of the 13,000 wild migratory birds that federal and state officials have tested since Apr 26, the US government announced yesterday.
(CIDRAP News) Final tests confirmed that two mute swans in Michigan had a mild strain of H5N1 avian influenza virus, not the lethal Asian variety, the US Department of Agriculture (USDA) announced yesterday.
(CIDRAP News) Leading medical researchers yesterday announced the formation of a consortium to unlock genetic and other data on avian influenza in the hope of improving the understanding of how viruses such as H5N1 spread and evolve.
(CIDRAP News) Avian flu experts in two of the countries with the most human H5N1 avian influenza cases to dateVietnam and Thailandare warning that the antiviral drug oseltamivir may mask the infection and complicate laboratory detection.
(CIDRAP News) The World Health Organization (WHO) today changed the H5N1 avian influenza strains recommended for candidate vaccines for the first time since 2004, causing some experts to question how far the virus has evolved.
The WHO's new prototype strains, prepared by reverse genetics, include three new H5N1 subclades.
