Design and application of a vaccine for syphilis is proposed. Syphilis, once a widespread and crippling disease, has decreased in prevalence and significance due to public health education and the use of penicillin, which is extremely effective in curing the disease. This decline has reduced the urgency for a vaccine for syphilis. However, in recent years the incidence of syphilis has been increasing. A persistent reservoir remains in highly impacted groups such as sex workers and men who have sex with men. It is proposed that the critical application of a vaccine for syphilis to these groups could eventually eliminate this disease. Evidence is presented that the most effective immune response to syphilis infection is delayed type hypersensitivity (DTH). In this review a design for a vaccine for syphilis directed to the induction of DTH is described.
