**Semantic type:** Amino Acid, Peptide, or Protein|Immunologic Factor|Pharmacologic Substance

**Definition:** A peptide vaccine derived from cytomegalovirus (CMV) antigens with potential immunostimulating activity.

Infection with the herpesvirus CMV may play a significant role in tumor cell initiation and progression as well as chemoresistance.
