(1) Specificity: The immune response is triggered by a specific antigen and defends against only that antigen. (2) Versatility: The immune system can differentiate among hundreds of millions of antigens that it might encounter during a normal lifetime. (3) Memory: The immune response following the second exposure to a particular antigen is stronger and lasts longer than before. (4) Tolerance: Some antigens, such as those on your own cells, do not elicit an immune response.
