The peptide production method of the present invention produces a peptide
(SEQ ID NO: 1) of a protein from Plasmodium falciparum, which is
effective as a malaria vaccine. The method produces the peptide of SEQ ID
NO: 1 by linking the fragments (i) through (v) shown below: (v)
Asn-Asn-Asp-Xaa (SEQ ID NO: 2); (iv) Asp-Phe-Lys-Thr-Pro (SEQ ID NO: 3);
(iii) Asn-Lys-Thr-Tyr-Asp-Leu (SEQ ID NO: 4); (ii) Phe-Tyr-Asn-Ser-Glu
(SEQ ID NO: 5); and (i) Xaa-Ala-Ser-Glu (SEQ ID NO: 6), where `Xaa` in
(i) and (v) represents zero or any arbitrary number of amino acid
residues.
