The report compares the compatibility, efficacity and serology response of two bivalent anti-foot-and-mouth disease vaccines (OC). One is oil-adjuvanted and the other based on diethyl-amino-ethyl-dextran (DEAE-Dextran). After vaccination no general clinical or local reactions are normally observed. Tissular reactions at the inoculation site are more severe with the oil-adjuvanted vaccine than with the DEAE-Dextran vaccine. Meat inspection, about three months after injection of the vaccine, showed the lesions to be in regression and negligible. The control of activity has been performed by the virulence test. For the oil-adjuvanted vaccine, protection against O1-Lausanne, 5, 21 and 90 days after vaccination is 90%, 80-100% and 55% respectively. For the DEAE-Dextran vaccine, these levels of protection are 80% after 5 days and 20-70% after 21 days. The percentage of swine protected against C-Noville 35 days after vaccination is 100% for the oil-adjuvanted vaccine and 70% for the DEAE-Dextran vaccine. The evolution of the amount of serum antibodies was followed for three months by the method of seroneutralization on cell cultures.
