Serological responses to vaccination: (A) Antibody responses to the PEDV spike protein as assessed by ELISA (B). Antibody responses to the PEDV nucleoprotein as assessed by ELISA (C). Virus neutralizing antibody responses as assessed by a fluorescent focus neutralization (FFN) assay. X axis, Days post vaccination; Y axis, ELISA OD value expressed as a signal to positive control ratio; Line with dots, Unvaccinated controls; Solid line, Heat and RNAse treated vaccine; Dashed line, Irradiated vaccine. Mean duplicate values for 8 pigs and standard deviations are presented. *Significantly different from the unvaccinated group, #Significantly different from the other vaccine group. *p < 0.05 by the Student's T-test.
