Herpes simplex virus (HSV) most frequently initiates infection at a mucosal surface; thus mucosal immune responses are likely to be important in defense against HSV infection. We have examined the effects of eliciting mucosal as well as systemic immune responses on protection against genital challenge infection with virulent HSV-2 in mice immunized with a replication-defective mutant of HSV-2. In addition, we have examined the types of immune responses elicited by immunization by the different routes under conditions known to provide protection. We observed that immunizations at parenteral and distal mucosal sites generate immune responses that have an additive effect in protection against challenge infection with virulent HSV-2. Immunization at either of these sites alone prevented paralysis and death after challenge virus infection and reduced replication of the challenge virus in the genital mucosa, although subcutaneous immunization was more effective in reducing virus replication. Simultaneous immunization at the two sites led to the greatest reduction in mucosal replication of challenge virus. The type of response generated was also affected by the route of immunization. Subcutaneous immunization results in a strong systemic immune response that is somewhat biased toward a Th1 T cell response, while intranasal immunization induces mucosal as well as systemic immunity, as evidenced by HSV-specific IgA in vaginal secretions, and a stronger bias toward a Th1 response. These results suggest that mucosal immunization may complement protective immunity against HSV-2 genital infection generated by parenteral immunization with replication-defective mutant virus.
