Induction of Protective Immunity against Malaria by Priming-Boosting Immunization with Recombinant Cold-Adapted Influenza and Modified Vaccinia Ankara Viruses Expressing a CD8+-T-Cell Epitope Derived from the Circumsporozoite Protein of Plasmodium yoelii

摘要

We immunized mice with an attenuated (cold-adapted) influenza virus followed by an attenuated vaccinia virus (modified vaccinia virus Ankara), both expressing a CD8+-T-cell epitope derived from malaria sporozoites. This vaccination regimen elicited high levels of protection against malaria. This is the first time that the vaccine efficacy of a recombinant cold-adapted influenza virus vector expressing a foreign antigen has been evaluated.
