ATTENUATED AFRICAN SWINE FEVER VIRUS WITH DELETED GENE AND USE OF SAME AS VACCINE

摘要

Provided is an attenuated African swine fever virus, a gene of which has been deleted, which can be used as a vaccine, a vaccine thereof, and a construction method therefor. The construction method comprises using Chinese epidemic strain Pig/CN/HLJ/2018 of African swine fever, and deleting a virulence gene of the African swine fever virus by means of gene engineering technology, thereby obtaining viruses, which have undergone gene deletion, from which MGF360-505R has been deleted and both CD2V and MGF360-505R have been deleted.
