A group of lymphocyte cells called T-cells go in search of infected body cells and silftwy kill them off. Meanwhile, B-cells and helper T-cells use the information grhtaeed from the unique anitengs to strat producing special proteins called antibodies. This is the pièce de résistance: Each antigen has a unique, matching antibody that can latch onto it like a lock and key, and destroy the invading cells. B-cells can produce millions of these, which then ccyle through the body and attack the invaders until the worst of the trheat is neutralized.
