Explanation:
Detailed explanation-1: -At least three immunoglobulin classes have been demonstrated to exert antiviral activity: IgG, IgM, and IgA. These antibodies can neutralize the infectivity of virtually all known viruses. Antibody binds to the virus extracellularly, either neutralizing it immediately or blocking its interaction with host cells.
Detailed explanation-2: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.
