When the immune system mistakenly attacks a normal part of the body, this is known as autoimmunity.
Autoimmunity that causes hypOthyroidism (low thyroid) is called Hashimoto's Thyroiditis. This condition can also cause hypERthyroidism as well. There are specific antibodies in patients with Hashimoto's.
Autoimmunity that causes hypERthyroidism is usually a condition known as Graves' Disease. There are specific antibodies in patients with Graves' Disease.

Yes, bone marrow is a key component of the immune system. It produces white blood cells, including lymphocytes (T cells and B cells) that play a vital role in the body's defense against pathogens and foreign invaders.
Immune system is an essential for all living organisms. In bodies immunity system helps to protect the body from harmful diseases. Vitamins , carbohydrates are essential to boost immune system in a body.
If you are allergic to something, you will break out in a rash with red itchy bumps. You may have symptoms like watery eyes, stopped up nose, or swelling. Severe allergic reactions involve swelling inside the bronchial tubes, leading to difficulty breathing and even death.
Rh is a factor on blood cells that act as an antign (allergen) to those without it. The Rh refers to the fact that it was first found in Rhesus monkeys. If a mother is Rh negative (15% 0f the population in US) and her developing baby is Rh negative there is obviously no problem. If, however, the mother is negative and the baby is positive, the problem results. This only occurs when the father is Rh positive(+) and the mother is Rh negative(-). (lacking the Rh factor). The Rh factor passes the placental barrier, and the mother's immume system produces antibodies to the (+) factor. The antibodies pass the placental barrier also, and attacks the hemopoetic system on the baby (blood producing red marrow). As more a more red blood cells (RBC's)are destroyed by the antibodies, the blood system tries to increase the rate of cell production and starts sending immature RBC's in to the circulation. These are nucleated RBC known as Erythroblasts and the cells are not capable of transporting oxygen and carbon dioxide normally. The medical condition is known as "Erythroblastsis Fetalis" The inability of oxygen transport can lead to developmental anomalies and even death of the fetus. A Rh positive mother and either a Rh (+) baby or a Rh (-) baby have no problem. As with an allergic reaction, each subsequenial pregnancy causes greater allergic reaction. This can be prevented by the simple injection of a medicine (RhoGAM) to prevent the reaction ...sort of like an allergy injection.
Vaccines help prevent disease because they insert a slightly different strain (or species) of the disease. They usually change the disease so that it only effects chickens. Your body learns basiclly how to fight it and reconize it.
