Low vitamin B12.: pernicious anemia is a LOW vitamin B12 state. This occurs when the body fails to make enough of a specific protein to enable the body to absorb vitamin B12. This usually occurs when the immune system attacks a specific cell in the stomach that produces the needed protein. Since the body can't absorb vitamin B12 through the stomach it can be given in a shot and even under the tongue.

See below: B-12 anemia is a deficiency in vitamin b-12 (cobalamin). Pernicious anemia is a deficiency or lack in intrinsic factor (produced by cells in the stomach) which is a protein essential for absorption of vitamin B12 in the ileum (small intestine). Pernicious anemia requires replacement of intrinsic factor &/or b-12. B-12 anemia needs only b-12 supplementation.
