Abstract
This article reviews the rationale for using marker vaccines and companion diagnostic tests in the eradication of pseudorabies virus (PRV). Recent advances in vaccinology and epidemiology indicate that, despite the inability to induce complete immunity, vaccination is a useful tool in the battle against PRV. This review focuses on the effectiveness of vaccination under field conditions and on herd, management and regional factors that are associated with PRV introduction or transmission.
