Despite the widespread use of the conventional inactivated foot-and-mouth disease (FMD)
vaccine, its immunogenicity is poor and the duration of its protection is short. In this study,
humoral response to commercial ready-to-use MontanideTM ISA 201 VG and MontanideTM
ISA 61 VG oil adjuvants and a common adjuvant MontanideTM ISA 206 VG developed by Seppic
Inc., were evaluated for FMD antigens in sheep and double oil emulsion (w/o/w) formulations
of MontanideTM ISA 201 and 206 and single oil emulsion (w/o) of MontanideTM ISA 61 have
been prepared by using current FMDV antigens (O/TUR/07, A/ASIA/G-VII, A/TUR/16 and ASIA/
TUR/15). The animals (n=48) were vaccinated subcutaneously with formulations and five
sheep were maintained as an unvaccinated control group. Blood samples were taken at day
0, 7, 14, 21, 28, 60, 90, 120 and 150. Virus neutralization and liquid phase blocking ELISA tests
were used to compare antibody response to vaccines prepared by using different MontanideTM
mineral oils. The results showed that vaccines prepared by using MontanideTM ISA 61 and
201 gave better antibody response to FMD antigens than MontanideTM ISA 206 formulation,
although results were not statistically significant for certain days of sampling. Moreover,
the overall type O antibody response of MontanideTM ISA 201 was found to be superior to
MontanideTM ISA 61.
