Quizplus · Accepted Answer

Foreignness, or how distinct an antigen is from the body's own cells, is the most important determinant of immunogenicity. This is because the immune system is designed to recognize and respond to foreign invaders, so antigens that are more foreign will trigger a stronger immune response. Size, complexity, and quantity can also play a role in immunogenicity, but they are not as important as foreignness.
