Why is immunology important?

The immune system acts as the body’s defense mechanism, protecting the cells, tissues, and organs from invading pathogens and infections using various lines of defense. Failure in the functioning of the immune system can result in different types of diseases including allergies, autoimmunity, and cancer. 

Immunology plays a key role in the development and creation of effective vaccines against different pathogens. It is also pivotal in identifying, diagnosing, and treating new immune system diseases and disorders. 

Immunology has also made organ transplantation and blood transfusion much safer by helping to correctly identify and cross-match blood groups. 

Researchers use their expert knowledge of immunology in an ongoing effort to develop new research techniques and tools to treat various autoimmune disorders and cancer.
