An antigen can be anything! An antigen can be thought of as anything that can cause your immune system to spring into action and fight it.  That could be a cold or a flu virus.  It could also be peanuts!  People who are allergic to peanuts experience an immune system response when peanuts (antigens) are introduced to their body and their immune system thinks they're bad and so the immune system attacks.  People have allergies to a wide variety of things, so almost anything can be an antigen.
