Abstract
Lethal infection with herpes simplex virus types 1 (HSV-1) and 2 was effectively prevented by previous immunization with a detergent-soluble extract (DSE) of virus-infected cells, free from infectious virus without any adjuvant. This protective immunity seemed to last for at least 1 mo. Neutralizing antibodies were elicited in mice immunized with DSE, but at a lower level than in animals immunized with live or killed virus. DSE did not protect athymic nude mice from death by HSV-1 infection, suggesting that a T cell-mediated immune response plays a major role in the protection.
