Abstract

Pre-existing immunity to human adenovirus serotype 5 (AdHu5) has been shown to suppress the immunogenicity of recombinant Ad5 (rAdHu5) vector-based vaccines for human immunodeficiency virus type 1 (HIV-1) in both preclinical studies and clinical trials. As a potential solution to this problem we developed adenovirus vaccine vectors of chimpanzee origin. In the present study we assessed the immunogenicity of various chimpanzee adenovirus vectors in a prime/boost regimen to HIV-1 envelope and SIV Gag-Pol in rhesus monkeys and their ability to protect against pathogenic viral challenge. Although rAdHu5-primed monkeys had higher magnitude T cell responses than rAdC7 or rAdC68 prior to challenge, the rAdC7-rAdC1/C5 and rAdHu5-rAdC1/C5 immunizations resulted in comparable magnitude recall cellular immune responses and comparable level of control of viremia post-challenge.
