Groups of 20 animals were used for data analysis.
P < 0.01 by Student's t test compared with immunization with IFA alone.
Amino acid homologies with the peptide MBPp87–99 are in bold.
Note that the HPV 7 sequence we use is three amino acids shorter at its NH2 terminus than that used by Ufret-Vincenty et al. (1).
P < 0.001 by Student's t test compared with immunization with MBPp87–99.
