In the process of eradication of IBR in Belgium, vaccination with marker vaccines is recommended since 2010. In this process, farmers use a registered mandatory vaccination protocol with available commercial vaccines with single shot primovaccination. The aim of this study was to show that a double primovaccination could successfully cut the circulation of IBR in youngstock.

We struggled with IBR enzootia in these two large farms using conventional live vaccines, and we believe that the double primovaccination with gE/tk deleted vaccine permitted a drastic diminution of the circulation. Both farms are now heading toward negative for IBR certification, and kept the double primovaccination protocol.
