Evaluation of Waldmann-type and Frenkel-type foot-and-mouth-disease vaccines in pigs.

چکیده
The immune response of pigs to one and two injections of Waldmannand Frenkel-type monovalent FMD type C vaccines and to experimental infection with FMD type C virus was studied. Neutrali zing serum antibody titres were determined, and challenge infections were performed 4 and 8 weeks after the first vaccination, and 2 weeks after the second one; essentially the same schedule was followed with the experimentally infected pigs except that these were challenged 4 weeks after the second exposure.
