The interference of maternally derived antibodies on CSFV vaccines. Piglets with high maternal derived antibody were immunized with two doses of CSF-E2 vaccine (group H, n = 6), LPC vaccine (group I, n = 6), or placebo (group J, n = 6) at 3 and 6 weeks of age and received a booster immunization with one dose of LPC vaccine at 16 weeks of age (*). The dynamics of the CSF-specific antibody level were monitored by using an IDEXX CSFV Ab blocking ELISA test kit and the gray dotted line indicated adequate antibody level (blocking percentage > 40%). Different letters indicate statistically significant difference (p < 0.001)
