| Research Abstract |
We analyzed the effect of a prophylactic AIDS vaccine inducing confined replication of an avirulent virus on cytotoxic T lymphocyte (CTL) responses in macaques after simian immunodeficiency virus (SIV) challenge. Our analysis revealed that prophylactic vaccination results in dominant induction of vaccine antigen-specific CTL responses post-viral exposure but delays SIV non-vaccine antigen-specific CTL responses. These results imply a significant influence of prophylactic vaccination on CTL immunodominance post-viral exposure, providing insights into antigen design in development of a CTL-inducing AIDS vaccine.
