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.
