Fig. 4. Antibody titers in pigs vaccinated with the experimental foot-and-mouth disease vaccine, O JC-R. (A) Type O SP-ELISA results. (B) VN titers against O/Jincheon/SKR/2014. (C) VN titers against O/Boeun/SKR/2017. (D) VN titers against O Taiwan97. The dotted lines in SP-ELISA results indicate 50% inhibition, which is the positive cut-off in the test. The dotted lines in the VN test show 1.5 log VN titers (1:32). The arrows indicate the challenge time at 28 DPV.
