Foot-and-mouth disease (FMD) is ahighly contagious viral disease that affect both domesticated and wild cloven-hoofed animals. FMD has taken an enzootic form in Egypt. So It was necessary to make many studies about how to control this dangerous disease by vaccination using imported or locally produced vaccine. Despite years of biannual vaccination of cattle against foot-and-mouth disease (FMD) using trivalent locally prepared and imported vaccine, the disease still uncontrolled in Egypt. There is no strategic plan for immunization against the disease using local or imported FMD vaccines. At how old are the newborn calves vaccinated and after how many weeks are they revaccinated? Is vaccination every four months or six months in both dairy cows or herds of fattening calves recommended? In order to answer these questions, the experiments of this thesis were designed to evaluate the immune response of the imported vaccine in a farm in Suez governorate and comparing with Giza governorate farm in which the locally produced vaccine is used to test the serological equivalence of viruses used in the vaccine.And to evaluate the immune response of the imported vaccine in a farm in Gharbia governorate
