An antigen is a body's system for creating antibodies to fight infection. A pathogen is an infectious agent (or germ).
Pathogens are the disease causing agent while antigens are found in the antibodies that fight against the pathogens. So in short, no they aren't the same.
All germs are pathogens but all pathogens is not germs.
Lymphocytes
Antigens: BUT that is only true if the antigens cause a harmful reaction when they invade.

Proteins that are pathogens are called antigens. These antigens can trigger an immune response in the body, leading to the production of antibodies to fight off the pathogen.
Antibodies attach to antigens preventing them from attacking cells in the body. Antitoxins attack antigens and destroy them
your body produces antigens to fight against the pathogens and imune you agaist diseases.
The molecules on pathogens that enable the immune system to distinguish one kind of pathogen from another are called antigens. Antibodies destroy pathogens by binding to the antigens on the pathogen.
Antigens work as bar-codes to help the immune system differentiate between body cells and pathogens. Normally the body will not attack its own cells, but is programmed to attack those with foreign antigens.
