The present invention relates to biologically-active copolymera and to compounda that can be safely used to cause the thymus of an animal or human to increase in size, thereby replenishing the T-lymphocyte population. When injected into an animal or human with an antigen, the biologically-active copolymers cause immunosuppression to the antigen. The biologically-active copolymer of the present invention is a safe and non-toxic formulation that can effectively be administered to animals or humans. The biologically-active copolymer can be mixed in an oil and water emulsion and administered to an animal or human by injection.
