Detailed explanation-1: -“Antigens” are molecular structures on the surface of viruses that are recognized by the immune system and are capable of triggering one kind of immune response known as antibody production.

Detailed explanation-2: -Any substance capable of generating such a response is called an antigen, or immunogen. Antigens are not the foreign microorganisms and tissues themselves; they are substances—such as toxins or enzymes—in the microorganisms or tissues that the immune system considers foreign.

Detailed explanation-3: -An immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that look to be foreign and harmful to the body. The immune system protects the body from potentially harmful substances by recognizing and responding to antigens.
