Herpes simplex virus 2 (HSV-2) causes genital herpes and increases the risk of acquisition and transmission of HIV. An HSV-2 vaccine is not available. We will study a replication-defective HSV-2 vaccine, HSV529, that is deleted for 2 essential viral proteins, that can infect, but not replicate in normal cells. The goals of the study are to determine (a) the safety of HSV529 vaccine in persons with or without HSV infection, and (b) the ability of the vaccine to elicit immune responses to HSV-2 including virus-specific antibodies and T cell responses to the virus. Three groups of 20 subjects each will be randomized and will receive 3 doses of HSV529 (15 subjects per group) or saline placebo injection (5 subjects per group). Each subject will be followed for 6 months after the last dose of vaccine. The 3 groups will be (a) subjects who were infected with HSV-2 in the past but may or may not have been infected with HSV-1 (HSV-1+/-/HSV-2+), (b) subjects who have been infected only with HSV-1 (HSV-1+/HSV-2-), and (c) subjects who have not been infected with HSV-1 or HSV-2 (HSV-1-/HSV-2-). Vaccine or placebo will be administered on Day 0 and approximately 1 month and 6 months after enrollment.
