Recombinant adenovirus vaccines show great promise for generating protective immunity against infectious agents and tumors. Our studies have identified several interesting biological features of the adenovirus vector that influence the T-cell response. Notably, we have demonstrated that following immunization with adenovirus vaccines, the transgene antigen remains available to the system for a longer period than would be expected, resulting in a T-cell population with a sustained effector phenotype. The implications of these observations with regards to the utility of adenovirus vaccines are discussed.
