Oral immunisation of wild boar against classical swine fever (CSF) in the German federal state of Baden-Württemberg has been evaluated on the basis of the seroprevalence rates after application of an improved immunisation procedure consisting of three double vaccinations per year (in spring, summer and autumn). The seroprevalence in the vaccination area increased continuously until the third immunisation campaign (72.4% seropositive animals). Later, a decrease of the seroprevalence rates was detected, especially in young boars. Although in the infected area the seroprevalences were higher, in principle, the same trend could be found in the surveillance zone. The development of the monthly seroprevalence rates of young boars during the first year of their life showed that the new immunisation procedure had a positive effect on their immunisation rate. Fifty percent and more of the wild boar shot at the age of 6–12 months were antibody positive. Neutralising antibody titre levels were the same in young boars (on average 812 ND50) and in sub-adults (on average 997 ND50). Individual antibody positive animals may be detected for more than 2 years after completion of the vaccination programme.
