When an antigen enters the body and B cells recognize it (either because of previous exposure to the disease or vaccination against it), the B cells produce antibodies. Once the antibodies attach to the antigen (think of a lock and key arrangement), they signal the rest of the immune system to attack and destroy the invader.
