DPV day post vaccination (first dose), DPC day post challenge. Pigs were challenged on 35 DPV

(−/−): Control pigs without challenge; (−/+): Control pigs challenged with CSFV

One-dose: Pigs vaccinated with one dose KNB-E2 and then challenged with CSFV

Two-dose: Pigs vaccinated with KNB-E2 twice and then challenged with CSFV
