title: Efficient induction of protective anti-malaria immunity by recombinant adenovirus.
abstract: The immunogenicity of a previously constructed replication-defective recombinant adenovirus expressing the CS protein of Plasmodium yoelii was compared with that of irradiated sporozoites. We found that immunization of BALB/c mice with a single dose of this recombinant adenovirus induced a much greater CS-specific T-cell response compared with immunization with irradiated sporozoites. More importantly, we found that this recombinant adenovirus induces similar or higher levels of protective immunity than those induced by irradiated sporozoites, eliciting an appreciable resistance to malaria infection.
