ABSTRACT:
Attenuated pseudorabies viruses are provided which comprise DNA including a sequence essential for replication of the attenuated virus, at least a portion of which is present in a sequence essential for replication of a naturally-occurring pseudorabies virus, from which at least a portion of a repeat sequence has been deleted. These viruses are useful as vaccines for immunizing animals against pseudorabies virus disease.
The invention also provides methods of preparing attenuated pseudorabies viruses.
