This special issue of Eurosurveillance is dedicated to the memory of Andrea Infuso, a dear and respected colleague and friend, who died suddenly on 20 September 2005 at the age of 44. Andrea was actively involved in the preparation of this special issue on vaccination and tuberculosis. As EuroTB coordinator since 2000, his knowledge of and contacts with all European experts involved in tuberculosis surveillance in Europe were very valuable in conceiving this thematic issue. The Euroroundup published in this issue, European survey of BCG vaccination policies and surveillance in children, 2005, written by Andrea as first author, is a posthumous publication.
