An Antigen
Basically to explain this, an antigen is any type of pathogen that causes disease, while an antibody is something that combats against the antigen.
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).
