Virion host shutoff (vhs)-deficient herpes simplex virus (HSV) was tested as a therapeutic vaccine in a mouse model of UV light-induced recurrent herpetic stromal keratitis. Four weeks after primary corneal infection, mice were vaccinated intraperitoneally with vhs(-) vaccine or control. Four weeks after vaccination, the eyes of latently infected mice were UV-B irradiated to induce recurrent virus shedding and disease. Post-irradiation corneal opacity in latently infected, vhs(-)-vaccinated mice was significantly reduced compared to control-vaccinated mice (P=0.007 to 0.035). The incidence and duration of recurrent virus shedding were the same in both groups. Antibody titres were increased (P=0.05) and delayed type hypersensitive responses were unaffected by vhs(-) vaccination. Combined with studies using different vaccination timing and vhs(-) genotypes, these data suggest that deletion of vhs is a useful strategy in the development of a therapeutic HSV vaccine, and that temporal and genetic factors influence vaccination outcome.
