Antibodies help our body in an extremely targeted way to fight infections, such as with viruses or bacteria. They are formed by the immune system to specifically attack an invader, whatever it is. With vaccinations, the antibodies are formed to prevent specific viral or bacterial infections. Antibodies are also involved in allergies and allergic reactions as well as in so-called autoimmune diseases. What is new, however, is that they are now also being used as medications for non-infectious illnesses, in this particular case, chronic pain and migraine.
