Development of a Chimeric Vaccine Providing Protection Against the Type A ASIA/Sea-97 FMDVs in East Asia.

ABSTRACT: Background/Objectives: Foot-and-mouth disease (FMD) remains a significant threat to livestock, particularly in the pool 1 region (East Asia), where serotype A is prevalent. Vaccination is the most effective control measure, and the selection of the appropriate vaccine strain is critical for ensuring effective protection. The A/ASIA/Sea-97 lineage (and its G1 and G2 sublineages) has been reported in this region, necessitating the development of an appropriate vaccine. This study aimed to develop a potent candidate vaccine strain capable of providing effective protection against the G1 and G2 sublineages of the A/ASIA/Sea-97 lineage. Methods: Chimeric vaccine development was achieved by replacing and inserting antigenic sites derived from the A/ASIA/Sea-97 G1 (VP4, VP2, and VP3
