| Outline of Final Research Achievements |
We have generated baculovirus- and adenovirus-based malaria vaccines expressing Plasmodium circumsporozoite protein (PfCSP) or PfCSP-Pfs25 fusino protein. Immunization of mice with these viral-vectored vaccines induced high anti-PfCSP and Pfs25 antibody titers and cellular immune responses. These results clearly demonstrated that our vaccines possesses multifunctional effects on induction of both humoral and cellular immune responses. We successfully achieved sterile protective efficacy of our vaccines against sporozoite challenge. Moreover, heterologous prime-boost immunization regime using baculovirus- and adenovirus-PfCSP-Pfs25 elicited 99% transmission blocking activity. The present study shows great potential of our vaccines as next-generating malaria vaccines.
