Genetic Diversity and Temporal Shifts of Porcine Reproductive and Respiratory Syndrome Virus Type 2 (PRRSV-2) Strains in Japan (2020–2023): Evidence of Modified Live Vaccine Influence on Cluster Distribution

2025-09-30

Abstract excerpt

<h4>Background: </h4> Porcine reproductive and respiratory syndrome virus type 2 (PRRSV-2) remains a significant threat to swine production globally, including Japan. While the genetic diversity of PRRSV-2 has been reported previously, the potential association with modified live vaccines (MLV) is not well understood. This study aimed to characterize PRRSV-2 strains currently circulating in Japan and assess possib...
