[Production, control and use in swine of anti-foot-and-mouth disease vaccine in oil adjuvant].

A certain number of parameters involved in the manufacture, control and use of an efficacious vaccine against foot-and-mouth disease have been studied. This report considers the problems raised by the standardization of the raw material constituent to the vaccine as well as the different types of innocuity and activity testing carried out on sows, young pigs and bacon pigs. Special attention is given to virulence testing methods, to the criteria allowing evaluation of the quality of the vaccines and to the transmission of maternal immunity of the sows to their piglets and its incidence on the vaccination schedule.
