antibodies are transfered from mother to child at birth and through breast milk to nursing infants
a person with type A blood has type A antigens and anti B antibodies, a person with type AB blood has both type A and B antigens and no antibodies and also, we don't get fresh supply of antibodies from organic and healthy diet but those diets rather help improve our immunity.
