Fig. 3. Comparison of antibody responses in pig and cattle vaccinated with the experimental foot-and-mouth disease vaccine with an ISA 201 oil adjuvant. (A) Antibody responses (ELISA and VNT) of pigs at the 3rd week post vaccination (wpv). (B) Antibody responses (ELISA and VNT) of pigs at the 4th wpv. (C) Antibody responses (ELISA and VNT) of pigs at the 8th wpv. (D) Antibody responses (ELISA and VNT) of pigs at the 12th wpv. (E) Antibody responses (ELISA and VNT) of cattle at 4th wpv. (F) Antibody responses (ELISA and VNT) of cattle at the 8th wpv. (G) Antibody responses (ELISA and VNT) of cattle at the 12th wpv. PI, percent inhibition value in SP-ELISA; VN, virus neutralizing; ELISA, enzyme-linked immunosorbent assay; VNT, virus neutralization test. ^*p < 0.05, ^**p < 0.01, ^***p < 0.001.
