title: Vaccine prevents genital herpes in subgroup of women.
abstract: The herpes simplex virus (HSV) type-2 vaccine studied here prevented genital herpes only in women who were seronegative for HSV-1 and HSV-2 at baseline. Ten of these women would need to be vaccinated to prevent 1 case of genital herpes. The vaccine did not prevent infection with HSV-2 in these women. It did not prevent genital herpes in women with other HSV serologic status or in men. The usefulness of this vaccine is limited by the small subgroup in which it is efficacious. Determining which women fall into this subgroup could prove costly. It is possible that asymptomatic infected persons may spread HSV more readily. Emphasis on the use of condoms and antiviral agents should still be the first line in preventing the spread of genital herpes.
