摘要: Although present conventional foot-and-mouth disease (FMD) vaccines can prevent clinical disease, protection is short lived ( approximately 6 months), often requiring frequent revaccination for prophylactic control, and vaccination does not induce rapid against challenge or the development of carrier state. Furthermore, it clear that depends upon length immunization duration exposure/challenge methods. This review summarizes future strategies FMD control in endemic FMD-free countries, effectiveness cattle, sheep pigs, new methods selecting vaccine strains, suggestions alternative testing, new-generation efficacious their companion tests to differentiate infection vaccinated animals.
