Why the study?
Post-vaccination monitoring of antisera relies on liquid-phase blocking ELISA, and virus-like particles were evaluated to minimize the risk of live virus involvement during antibody detection for FMDV serotype O.
Does a VLP-based SPCE provide high specificity and sensitivity compared to LPBE for postimmunization antibody evaluation of FMDV serotype O?

May enable safer FMD seromonitoring without live virus; leaves open prospective validation before routine adoption.
Does a VLP-based SPCE provide high specificity and sensitivity compared to LPBE for postimmunization antibody evaluation of FMDV serotype O?
A novel VLP-based SPCE provides a highly sensitive and specific alternative to LPBE for monitoring FMDV serotype O antibodies without the risk of live virus involvement.
