Aujeszky's disease (pseudorabies) virus eradication campaign in The Netherlands

The Dutch Aujeszky's disease virus (ADV) eradication campaign is based on vaccination with glycoprotein E deleted vaccines. In the first stage of the programme, that was started in September 1993, the transmission of ADV must be reduced sharply. Subsequently, the remaining sources of virus need to be traced and eliminated. During the final stage, vaccination should be forbidden. This paper summarizes the observations made during a field study on the eradication of ADV by vaccination and reports the design and preliminary results of the first stage of the Dutch eradication campaign.
