The invention relates to a number of synthetic polypeptides which correspond to a part of the sequences of the Shiga B peptide chain. More specifically the invention relates to polypeptides corresponding to the residues 5 to 18, 7 to 26, 13 to 26 and 19 to 29 of said B, chain. The invention further relates to the conjugates of each of these with a suitable carrier and to polymers of each or these obtained by polymerization with a suitable polymerization agent: these can be used as effective vaccines which afford protection against Shiga toxin. Anti-peptide anti-sera are effective in neutralizing to a large extent the biological activity of Shiga toxin.
