    摘要: The present disclosure provides a type O foot-and-mouth disease virus-like particle antigen, wherein the type O foot-and-mouth disease virus-like particle antigen is type O CATHAY type foot-and-mouth disease virus-like particle antigen, and the type O CATHAY type foot-and-mouth disease virus-like particle antigen is assembled by VP0, VP3 and VP1 antigen proteins of type O CATHAY type foot-and-mouth disease virus. The type O foot-and-mouth disease virus-like particle antigen of the present disclosure has good immunogenicity. The prepared vaccine can produce complete protection against the O-type foot-and-mouth disease virus on the 14th day after immunization. The antibody titer produced is higher than that of the commercial inactivated vaccine, and the duration of immune protection can be maintained for at least 133 days. The disclosure also relates to the prepared vaccine composition, preparation method and use thereof.
