To identify immune response of leukocytes in peripheral blood of cattle vaccinated with an attenuated live Akabane virus vaccine, leukocytes were reacted with monoclonal antibodies which are specific to bovine lymphocyte surface antigens and assayed by the flow cytometry. Serum neutralizing (SN) test was used to measure antibody titers after vaccination, SN antibody was appeared to 7 days post-vaccination (PV) and 2-8 antibody titers were observed in 14 days PV. Proportion of $CD8^-$ MHC $class II^+$ expressing cells were rapidly increased at 3 days PV. $CD8^+$ MHC $class II^-$ cells were increased at 7 days PV. $CD4^+CD8^-,\;WC^+CD4^-,\;CD4^+CD8^+,\;WC1^-CD4^+, \;WC1^-CD8^+$, and $CD4^-CD8^+$ cells were highly increased at 3, 3, 7, 7, 14, 14 days PV, respectively.
