Abstract

The present invention provides an attenuated strain of porcine pseudorabies virus (PRV), in which said attenuated strain of PRV is a variant strain of PRV with inactivation of gI/gE/11K/28K proteins. In addition, the present invention also provides a vaccine composition comprising the attenuated strain of PRV as an antigen, a preparation method and use thereof. Proved by immunogenicity and pathogenicity testing of the live vaccine, said live PRV vaccine can provide a good protection for pigs with no clinical signs observed, indicating excellent immune protection.
