Article 1
For the purpose of this Decision the following definitions shall apply: 1. "Pre-emptive killing" shall mean the killing of susceptible animals on holdings within a certain radius around holdings placed under the restrictions laid down in Articles 4 or 5 of Directive 85/511/EEC. It is aimed at the urgent reduction of numbers of animals of susceptible species in an infected area. 2. "Suppressive vaccination" shall mean emergency vaccination of animals of susceptible species in identified holdings situated in a defined area, the vaccination zone, which is carried out exclusively in conjunction with pre-emptive killing as defined in paragraph 1. It is aimed at an urgent reduction of the amount of virus circulating and the risk of virus spreading beyond the perimeters of the area without delaying the pre-emptive killing. It shall only be carried out where the pre-emptive killing of animals of susceptible species must be delayed for an estimated time most likely exceeding the time required to effectively reduce the spread of virus by immunisation for at least one of the following reasons: - constraints on the execution of killing of animals of susceptible species in compliance with the provisions in Directive 93/119/EEC, - constraints on the available capacities to destroy killed animals in accordance with Article 5(2) second indent of Directive 85/511/EEC.
