The aim of this study was to survey the serological response to classical swine fever disease in vaccinated pigs in Cu Chi, Ho Chi Minh City. By using the PrioCHECK® CSFV Ab 2.0 ELISA test kit to detect antibodies against CSF in 410 vaccinated pigs and IDEXX CSFV Ag Serum Plus Test to detect the Erns protein of the CSFV in pigs without antibodies against CSFV. Results showed that the overall seroprevalence observed in vaccinated pigs in other Farms varied from 70% - 100% (P 40 - ≤ 60 days post-vaccination was 98.36%. The lowest rate was found in Group of 30 - ≤ 40 days postvaccination (51.96%). That grower pigs had the highest proportion of positive pigs for antibodies against CSFV accounting for 81.40%; next, the proportion of positive sows was 73.24%. Significant differences in the seroprevalence observed in vaccinated pigs across herd size, days post-vaccination, type of pigs (P < 0.05). In this study, no pig was found to contain CSFV antigen.
