Fig 1. Serum antibody responses in pigs after vaccination.

Fig 1.

(A) Geometric mean reciprocal titers of hemagglutination inhibition (HI) antibodies to heterologous challenge virus (KS-91088) were determined in sera from all pigs following vaccination and challenge. The reported HI titers are the average titers for each group. (B) At 28 dpv, serum samples were collected from all pigs to evaluate the serum IgG levels against KS-91088 virus using a whole-virus ELISA assay. Antibody levels were analyzed by average of each triplicate sample and reported as the mean of OD values of each group. The error bars indicate standard errors of the mean (SEM). The asterisks (*) represent a statistically significant difference between groups (**: p<0.01 and ***: p<0.001).
