RECOMBINANT HERPES SIMPLEX VIRUSES,VACCINES AND METHODS

摘要

Recombinant herpes viruses useful as effective ingredients in vaccines against both virulent HSV-1 and HSV-2 are disclosed. Methods of preparing the recombinant viruses, vaccines incorporating the viruses, and methods of immunizing by inoculation with the vaccines are also disclosed. The genomes of the recombinant viruses each comprise a mutant of the HSV-1 genome from which a portion thereof responsible for neurovirulence yet non-essential for growth is deleted. A gene from the HSV-2 gnome responsible for coding an immunity-inducing glycoprotein is inserted in the mutant genome between the end points of deletion therein.
