Abstract

The present disclosure provides a PRV gB protein fragment, or a conservative variant or active fragment thereof, the gB protein fragment has a high level of expression, the subunit vaccine antigen prepared from the gB protein fragment has a better immune effect than a subunit vaccine antigen prepared from gB protein. The invention also provides a preparation method of a subunit vaccine by using the gB protein fragment alone, or the gB protein fragment together with gD protein. This vaccine has a simple preparation method and provides excellent protection against disease caused by the porcine pseudorabies virus.
