The invention belongs to the technical field of vaccine, and more specifically relates to a porcine pseudorabies virus and porcine circovirus type II bivalent vaccine, and applications thereof. The porcine pseudorabies virus and porcine circovirus type II bivalent vaccine comprises inactivated porcine pseudorabies virus XF-1 strain, and porcine circovirus type II-WH strain. It is confirmed by the porcine pseudorabies virus and porcine circovirus type II bivalent inactivated vaccine that XF-1 strain can be prepared into combined vaccines used for preventing two or more than two diseases with other well-known antigens in the field of vaccine, a cognition error that concurrent infection of porcine circovirus type II and porcine pseudorabies virus is caused is eliminated, combination application of porcine circovirus type II and porcine pseudorabies virus at an appropriate rate is capable of achieving excellent effect, and vaccine development prospect is promising.
