  • Publication number: 20160106829
    Abstract: Disclosed herein is the attenuated vaccinia virus strain KVAC103 obtained by subculturing a vaccinia virus strain 103 times in VERO cells. The attenuated vaccinia virus strain KVAC103 has significantly low toxicity, shows reduced skin lesions, and, at the same time, induces effectively immune responses to poxvirus. Thus, it can be used as a poxvirus vaccine while causing less side effects.
