Pigs immunized with E2 subunit vaccine KNB-E2 were protected clinically from CSFV challenge. Pigs were immunized with KNB-E2 on Day 0 for the One-dose group and a second dose on 21 DPV for the Two-dose group. Two weeks after the second vaccination (35 DPV), pigs were challenged with 5 × 10⁵ TCID₅₀ CSFV strain Honduras/1997. a Body temperature was monitored daily after CSFV infection. Vaccinated pigs did not have body temperatures higher than 40.5 °C. b Shown are body weight measured every 3 days after CSFV challenge. Data are mean ± SEM for five pigs per group. * p < 0.05
