One effective recommendation for control of Foot and Mouth disease virus is the proper vaccination by a highly potent vaccine. Such a vaccine should be specific to the circulated field serotype of foot and mouth disease virus inducing rapid, highly protective immunity with a long duration. This research is concerned with using plant extracted oil adjuvants prepared from rapeseed oil mixed with or without Ginseng extracts and from Soybean oil as well with or without Ginseng extracts. Some humeral and cell-mediated immune responses were compared using the different plant-extracted oils cocktails and the mineral-based adjuvant called Montanide oil ISA 206 after one dose vaccination of the prepared vaccines at different interval times post vaccinations.  Lymphocyte blastogenesis, Interleukin -6, and Interleukin-12 showed higher expression in calves vaccinated by FMDV serotypes (O pan Asia, A Iran O5, and SAT2 / EGY/2012) with plant cocktails containing Ginseng extract comparable to that of plant extracts without Ginseng and Montanide oil ISA 206 adjuvants vaccines. It was found that FMD vaccine adjuvant with ginseng either with rapeseed or Soybean showed a higher post vaccinal cellular immune response than that without ginseng or ISA 206 alone. Estimation of the humoral immune response of vaccinated calves revealed that antibody against FMD virus serotypes O pan Asia, A Iran O5 and SAT2 / EGY/2012 by SNT and ELISA assay induced by the inactivated FMD adjuvant with rapeseed oil and ginseng vaccine and the inactivated FMD adjuvant with soybean oil and ginseng vaccine were higher than those induced by inactivated FMD adjuvant with Montanide oils 206. In contrast, the obtained antibody levels by the inactivated FMD adjuvant with rapeseed oil vaccine and inactivated FMD adjuvant with soybean oil vaccine was lower than those induced by inactivated FMD adjuvant with Montanide oils 206. So, it could be concluded that the use of plant origin oil adjuvant as rapeseed and soybean oil is considered a beneficial and alternative adjuvant to the imported mineral oil as it is much cheaper and induce better post vaccinal immune responses especially when mixed with ginseng extract.
