NCIt definition : A synthetic peptide vaccine consisting of amino acids 13 through 21 of the viral oncoprotein
human papillomavirus (HPV) 18 E6. The HPV 18E6 peptide cross-reacts immunologically
with both HPV type 16 and HPV type 18, the most common HPV types involved in cervical
cancer. Vaccination with HPV-18 E6:13-21 peptide may stimulate the host immune system
to mount a cytotoxic T-lymphocyte (CTL) response against tumor cells positive for
HPV 16 and 18.;
