- 1. 1EuFMD | Open Session special edition | #OS20se National Animal and Plant Quarantine Agency / Republic of Korea DURATION OF IMMUNITY IN CATTLE AND PIGS UNDER NATIONAL VACCINATION PROGRAMME AGAINST FOOT-AND- MOUTH DISEASE VIRUS Mi-Young Park (Presenter), YouJin Han, JiHyun Lee, Hyun Mi Pyo, Eun-Jin Choi, Doheon Kwon, Wonseok Shin, JaeMyoung Kim
- 2. 2EuFMD | Open Session special edition | #OS20se FMDV type-O antibody profiles in pigs and cattle obtained by PrioCHECK SP-O ELISAs and NA titer against homologous strain used in vaccine for pigs and cattle were observed. For both of animal, sero-positivity rate and NA titer against FMDV SP- O remained stable or tended to increase after administration of second dose. However, antibody responses for the MERIAL vaccine demonstrated a gradual decrease after 2 weeks for most pigs. Nevertheless, all vaccines used generated a sufficient antibody response (NA titer ≥1.5 log10) in most cattle and pigs for the duration of the trial.

For both of animal, sero-positivity rate and NA titer against FMDV SP-A remained stable or tended to increase after administration of second dose. High NA titers were induced in the group vaccinated with Bago as similar antibody profiles were demonstrated in antibody profiles to FMDV type-O.
- 4. 4EuFMD | Open Session special edition | #OS20se Objectives - Foot-and-Mouth-Disease antibody response profiles in cattle and pigs were observed for a certain period following the boosting vaccination in accordance with the recommended schedules. Outcomes - This study demonstrated the three routine vaccines adopted by the Korean-Expert-Committee for FMD vaccines confer enough long-term immunity for protective capability against FMDV when properly applied for the recommended vaccination regimes.
