Abstract Viral vectors are promising vaccine tools for eliciting antigen-specific T-cell responses. We previously showed the potential of recombinant Sendai virus (SeV) vectors to induce virus-specific T-cell responses in macaque AIDS models. Here, we have evaluated the immunogenicity of replication-competent V-knocked-out and replication-defective F-deleted SeV vectors in macaques. Intranasal replication-competent and replication-defective SeV immunizations both elicited robust systemic antigen-specific T-cell responses, whereas the responses induced by the former were more durable than those by the latter. However, even the latter-induced T-cell responses remained detectable in a local, retropharyngeal lymph node two months after the immunization. These findings are useful for establishment of a vaccine protocol using SeV vectors.
