Recombinant viruses expressing the foot-and-mouth disease type A protective antigen which inserted long term immunity enhancing gene, and a vaccine composition comprising the same

摘要

The present invention relates to a foot-and-mouth disease recombinant virus expressing a foot-and-mouth disease type A protective antigen and a vaccine composition comprising the same, and a recombinant foot-and-mouth disease virus and long-term high titer that can be usefully used as a vaccine strain having strong protection against foot-and-mouth disease type A virus It is possible to provide a foot-and-mouth disease vaccine composition capable of inducing protective antibodies.
