The present invention relates to particles, particularly virus-like particles (VLPs), comprising fusion polypeptides comprising selected repeat units derived from the repeating regions of Type I and Type II circumsporozoite proteins(CSP) of Plasmodium vivax(Pv), together with an amino acid sequence derived from the C-terminal PvCSP sequence. In some embodiments, the fusion polypeptide additionally comprises an amino acid sequence derived from the N-terminal PvCSP sequenceand/or a surface antigen polypeptide derived from Hepatitis B virus (HBV-S). The invention also relates to nucleotide sequences coding for such fusion polypeptides, vectors and plasmids comprising such nucleotide sequences, and host cells comprising such vectors and plasmids. The invention additionally relates to compositions, particularly vaccine compositions, comprising the fusion polypeptides or VLPs for use as vaccines for the prevention of malaria.
