[Considerations on the possible application of marker vaccines against swine fever in European Union].

The history of how the current control strategy against the Classical Swine Fever (CSF) in the EU came into being is described as well as the possibilities for applying conventional vaccines in the framework of this strategy. Concluding from these considerations, the preconditions for the permission of the application of marker vaccines are discussed and measures to be taken already before the registration of a marker vaccine are proposed.
