The disclosed vectors include vectors having deletions in the genes ICP0, ICP4, TCP22, TCP27 and TCP47, or alternative inactivating mutations, or vectors which express one or more of these genes with modified kinetics. The invention also relates to viral stocks of the inventive vectors, compositions thereof suitable for use therapeutically or for in vitro applications, and methods relating thereto. In another aspect, the invention provides a complementing cell, in particular a U20S cell, engineered to express ICP4 and ICP27 when the cell is infected with HSV for the production of the inventive vector. Said cells are disclosed as naturally complementing ICP0.<\/div>\n<\/section>\n<\/div>\n<\/section>\n<\/div>\n<\/div>\n<\/div><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-separator
