One way that researchers assessed protein similarities was by harnessing the immune system's ability to recognize foreign proteins. For example, the immune system of a rabbit will recognize a human protein as foreign and will mount an attack against it by making antibodies specific to that protein.

its actually that like recognises like.... same works wid the antibodies... so there's a specific antibody n antigen pair... so the one wich is not specific is regarded as foreign which cant b recognised by the body...

that very process is how vaccines are mady. They will take parts of a virus<dead> and introduce it into the blood. The lymphocytes, etc react by producing antibodies that are programmed to seek out the virus that it is programmed to kill and kill it.
