A laboratory in the Netherlands has identified a lethal influenza H5N1 virus strain that is transmitted among ferrets. These findings are under review by the National Science Advisory Board for Biosecurity (NSABB) to ensure that they do not constitute a threat to human health. Meanwhile both the popular and scientific press has been calling this …

Derek Smith, Professor of Infectious Disease Informatics, University of Cambridge, U.K., has developed a method for visualizing antigenic evolution by creating two-dimensional maps in a process called antigenic cartography. These maps are made with data that provide information on the antigenic properties of the pathogen. In the case of influenza virus, the data come from …
Hosts: Vincent Racaniello, Alan Dove, and Rich Condit On episode #112 of the podcast This Week in Virology, Vincent, Alan, and Rich review the making of a virulent poxvirus by insertion of the gene encoding IL-4, and severe 2009 H1N1 influenza due to pathogenic immune complexes.

Influenza researcher Peter Palese visited yesterday and spoke about “Pandemic influenza: Past and Future”. A key part of his talk was a review of his efforts to produce a universal influenza vaccine which protects against all strains. He used the following graph to make the point that when influenza pandemic strains emerge, there is insufficient …
After my lecture on influenza pathogenesis and evolution at the Northeast Laboratory Conference 2010 in Portland, Maine, I was asked if it is necessary to receive the influenza vaccine every year. This question was precipitated by my statement that the 2010-11 trivalent influenza vaccine contains the same swine-origin H1N1 strain as last year€™s monovalent vaccine. …
