FIGURE 1. Vaccination protocols.
The cartoon is an adaptation from Virnik et al. [19] and details the vaccination timeline used for this Indian rhesus macaque study. Animals CL6A and CL6J had received RA27/3 rubella vaccine strains and sham DNA. Macaques CL67, CL49, CL6V had received rubella type 1 and type 2 which were “no takes” and did not induce antibodies to rubella and also did not induce Gag-specific T cell immunity. The animals received sequential vaccinations with DNA and rubella vector type 3 or type 3*, referred to as rubella vector herein, expressing SIV Gag. The animals were analyzed for Gag-specific IFN-γ+ T cell responses, and macaques positive for the MamuA*01 haplotype were also analyzed for Gag CM9 tetramer responses.
