An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).

An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment. Antigens are: proteins, polysaccharides, glycoproteins, or glycolipids. Antibodies are specific for that antigen. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
