Encouraging results from North America on PCV2 vaccination and valuable European updates on immunity to the virus are reported to a major veterinary meeting held in the USA. Orlando in Florida, USA, is famous as the home of the Disneyland resort. Thisyear the town was the setting for some announcements that should cause pig producers everywhere to celebrate. Orlando gave the backdrop to an exchange between Europe and North America of some highly encouraging information over the costly diseases associated with the PCV2 porcine circovirus. This exchange formed a major part of the latest annual congress of the American Association of Swine Veterinarians. The visit to Florida in 2007 by the AASV not only brought the unveiling by European experts of valuable updates on circovirus pathogenesis and immunity, but also the presentation by the North Americans of amazingly successful results from vaccinating against PCV2 and its assortment of associated diseases collectively called PCVAD.
