In this special edition Eurosurveillance covers various aspects of the 2009 influenza A(H1N1) pandemic. The compiled articles provide information and data on epidemiological patterns, surveillance trends and a first analysis of vaccine effectiveness of the trivalent seasonal influenza vaccine for 2010/11 influenza season and of the monovalent influenza A(H1N1) 2009 vaccines. It also features a paper on the possible impact of media coverage on consultation rates.
