| Env IIIa | gp41 | 101–169 | B | Thermo Scientific |
| RT I | pol | 1–55 | B | NIBSC |
| RT II | pol | 56–110 | B | NIBSC |

NOTE. MVA, modified vaccinia virus Ankara; NIBSC, National Institute for Biological Standards and Control; WRAIR, Walter Reed Army Institute of Research.
DNA vaccine clade A–specific and clade B–specific peptides. All peptides were 15-mers with 10-aa overlap.
The peptides included in the Gag WR pool were specific for the HIV inserts in MVA and were 15-mers with an 11-aa overlap. This peptide pool was included in assays of samples obtained at the time of HIV-1 MVA boosting vaccination and 2 weeks after HIV-1 MVA boosting vaccination.
