Antibodies are proteins that are made in the blood or tissues as a direct response to the detection of specific antigens by the immune system. These antigens (antigens are anything that when introduced to the body cause the immune system to release antibodies) could be as a result of infection from a bacteria or virus, a protein found in different types of food, medicines or drugs, or any plant or animal substance that enters the body usually via the mouth, nasal passages, or the circulatory system. Antibodies are able to weaken or neutralise the effects of the offending antigen and help keep the body’s immune system strong and healthy.
