African  swine fever virus vaccine strain ASFV-G-?I177L serial passaging in pigs
ASFV-G-?I177L is a gene-deleted modified-live African swine fever virus (ASFV) vaccine strain that is incorporated in a commercially available vaccine to combat a devastating swine disease. As there are inherent safety risk associated with ASFV vaccine strains, we sought to investigate the safety of ASFV-G-?I177L in pregnant sows and its genetic stability in an in vivo passaging experiment.
