The patient returned for review 4 weeks, 18 weeks, 8 months, and 18 months after his initial examination and pretreatment with the vaccine. Four weeks after the first injection, the warts had improved substantially, particularly on his hands and knees. Ten weeks after his second injection, further substantial remission of several warts was noted. Approximately 4 months after commencement of the vaccine injections, there was more improvement and further regression of his warts. The areas substantially affected by cutaneous warts prior to vaccine administration, such as his hands, showed complete regression at 8 months (Figure 2). By 8 months, the patient showed complete regression of all 30 of his warts, and almost 18 months after the initial treatment with the vaccine, the patient was still free of all warts. No additional treatments were used during the follow-up period, and no warts were present 18 months after his initial treatment with the vaccine.
