Answer:
Immunologic techniques are used to treat disease by stimulating or suppressing the immune system to fight or prevent disease. These techniques include the use of vaccines, monoclonal antibodies, cytokines, and other immunomodulatory drugs. By using these techniques, doctors can help the body to recognize and eliminate cancer cells, foreign invaders like viruses and bacteria, and other abnormal cells. In addition, immunologic techniques can be used to treat autoimmune diseases, where the immune system attacks the body's own cells, by suppressing the immune response. Overall, immunologic techniques have a huge potential to revolutionize the way we treat disease in the future.
