The invention relates to an Eimeria maxima DNA vaccine of chicken, belonging to the field of biological veterinary drugs. A gene fragment Em8 of an antigen EmTFP250 at the spore stage of the Eimeria maxima of the chicken is cloned by utilizing the molecular biology technology, and the fragment has higher antigen index and the centralized T cell epitope. The gene fragment is connected with a chicken interleukin-2 (chIL-2) gene in series, thereby constructing a vaccine expression vector pVAX-Em8-IL-2. The vaccine contains a plurality of T cell immune response elements and has the advantages of high safety, long maintenance time in vivo, simple preparation, good thermal stability, convenient storage and transport, time-saving and effort-saving use, and the like. Experiments prove that the immune regulatory DNA vaccine pVAX-Em8-IL-2 has good immune protection effect on the anti-Eimeria maxima infection.
