Immunological Rare Disease Market size is poised to grow at a significant CAGR of 11.9% over 2023-2029. The immune system is delegated to defend the body from attacks from outside or inside. Many diseases can affect the immune system reducing its ability to defend itself or inducing an abnormal response against external or internal antigens. Immunological Rare diseases, often known as orphan diseases, afflict a small percentage of the population at any given time. Orphan medications are those that are suggested for the treatment of rare disorders. An orphan immunological disease is one that affects less than 200,000 persons in the United States, according to the Food and Drug Administration (FDA). Furthermore, Several diseases can affect the immune system. Disorders associated with a reduced response against no self-antigens are called immunodeficiencies. On the other hand, primary immunodeficiencies (PIDs) are in most cases rare diseases associated with specific, genetic mutations. Immunology medications or substances modify immune responses by enhancing or inhibiting the immune system. They are used to fight infections as well as to prevent or cure autoimmune or immunological illnesses such as rheumatoid arthritis, psoriatic arthritis, type 1 diabetes, and others.    Rising awareness about rare immunological diseases such as Hypoalbuminemia and Hypovolemia, and Severe Congenital Protein C Deficiency in both developing and developed nations and the rising occurrence of immunological disorders due to environmental factors are critical reasons for increasing the demand for rear immunological drugs in the market. For instance, According to the Centers for Disease Control and Prevention's (CDC) 2020 National Diabetes Statistics report, the incidence of type 1 diabetes in the United States increased by 30% between 2017 and 2020. In 2017, there were 1.25 million people, which is expected to rise to 1.6 million by 2020.
