The International Vaccine Bank at Pirbright has recently installed large-scale vaccine formulation equipment for the preparation of oil-adjuvanted vaccines. Such vaccines are claimed to offer a number of advantages over Al(OH)3, particularly their ability to raise better immunity in pigs. This paper reports on the potency in pigs, cattle and guinea-pigs of foot-and-mouth disease vaccines prepared with two novel oil adjuvants, Montanide ISA 25 and 206 (Seppic, Paris). The results indicate that vaccines adjuvanted with these oils retain potency for a longer period than our conventional aqueous formulation, following storage at +4 degrees C, and elicit good antibody responses in both pigs and cattle regardless of injection route. In addition they gave no evidence of toxicity or prolonged pyrexia following their administration. Local reactions at the site of inoculation were not observed in cattle vaccinated intramuscularly, even following a booster dose. Pigs vaccinated intramuscularly only showed local reactions if the volume administered exceeded the 2.0 ml dose or the animals received a second vaccination. These observations on the efficacy of such oil formulated vaccines suggest that they have potential as an alternative to the current aqueous formulation.
