Antibodies are continuous being produced by activated B cells in your body as a response to your constant exposure to invaders. Antibodies are proteins and synthesized like proteins. Therefore, antibodies will be produced until you die. However, antibodies against a certain type of invaders may disappear when the invaders are eliminated.
