Described are methods for inducing an immune response in a subject against an antigen from a malaria-causing parasite, preferably P. falciparum, the method comprising: (i) administering to a subject a priming composition comprising adjuvanted proteinaceous antigen-comprising circumsporozoite (CS) protein or an immunogenic part thereof from a malaria-causing parasite； (ii) administering to the subject a first boosting composition comprising a recombinant adenovirus vector that comprises nucleic acid encoding CS protein or immunogenic part thereof from a malaria-causing parasite； and (iii) administering to the subject a second boosting composition comprising a recombinant adenovirus vector that comprises nucleic acid encoding CS protein or an immunogenic part thereof from a malaria-causing parasite, wherein either the first boosting composition comprises a recombinant adenovirus vector of serotype 35 (Ad35) and the second boosting composition comprises a recombinant adenovirus of Ad26, or wherein the first boosting composition comprises a recombinant adenovirus vector of Ad26 and the second boosting composition comprises a recombinant adenovirus of Ad35.
