(i) an acylated amino acid or a salt thereof;

(ii) a poly amino acid comprising at least one acylated amino acid or a salt thereof;

(iii) a sulfonated amino acid or a salt thereof;

(iv) a poly amino acid comprising at least one sulfonated amino acid or a salt thereof;

or

(v) any combination thereof.

2. A composition as defined in claim 1, comprising a mixture.

3. A composition as defined in claim 1, comprising a microsphere.

4. A composition as defined in claim 1, wherein said antigen comprises a peptide.
