Abstract
Undesired immune responses are suppressed by administering a nonimmunogenic material which comprises one or more haptens or epitopes corresponding to the antigen which causes the undesired immune response, the number and spacing of the haptens or epitopes being insufficient to trigger an immune response but sufficient to inhibit it. Also disclosed is an improved vaccine from which low molecular weight suppressive polymer has been removed.
