Persistence of anti-MPER antibodies elicited by rubella vectors in group 3 macaques. Anti-MPER antibody titers were measured for group 3 animals, DCVV (A), CL49 (B) and CL67 (C), between weeks 4 and 38 after live vector immunization. The same sera were tested as in Figure 9. The antibodies were near peak titers at 4 to 7 weeks post immunization. The titers declined 2 to 3-fold by 38 weeks, based on half-maximum binding, and this was nearly the same as anti-rubella antibodies in the same animals.
