A compound for modulating an immune response in medical application in the form of a hydrogel including an ultrapurified polymer, a complement modulator and a gelling agent. In a first embodiment the hydrogel has a pore size between 50 kDa and 100 kDa which generally functions as an immune response inhibitor. In a second embodiment, the hydrogel has a pore size greater than 200 kDa which generally functions as an immune response activator. The hydrogel may be applied directly, used to coat foreign materials, or used to encapsulate cellular or non-cellular material.
