    摘要: The present invention relates to methods for purification of Vaccinia viruses (VV) and/ or Vaccinia virus (VV) particles, which can lead to highly pure and stable virus preparations of predominantly biologically active viruses. The invention encompasses purifying a virus preparation in a sterilized way with high efficiency and desirable yield in terms of purity, biological activity and stability, aspects advantageous for industrial production.

    摘要: Provided herein are recombinant poxviruses comprising heterologous or native nucleic acids specifying excess double-stranded RNA (dsRNA) early in infection, which may further comprise heterologous nucleic acids encoding one or more costimulatory molecules, and/or heterologous nucleic acids encoding one or more infectious disease-associated antigens or tumor-associated antigens, as well as pharmaceutical compositions comprising such recombinant poxviruses and methods and uses thereof. The recombinant poxviruses provided herein enhance innate and adaptive immune activation in subjects compared to identical recombinant poxviruses lacking heterologous or native transcription units specifying excess early dsRNA.
