The overlapping sequences are underlined.
Results shown are the number of IFN-γ spots per million cells. —, no IFN-γ production detected at week 47 (prechallenge) and week 8 postchallenge. The major histocompatability complex class I typing of the chimpanzees (Patr class I) is as follows: for Vac1, A−, B*0201, C*0601, and A*0601, B*0101, C*0401; for Vac2, A*0401, B*1401, C*0203 and A*1401, B*16011, C*0502; and for the control animal, A*0601, B*0301, C*0901 and A*0401, B*0101, C*0401.
