The study of Immunology is essential because it is the first defense mechanism that fights against the disease-causing pathogens without any medication. The immune system forms antibodies to fight the pathogens on its own so that the body does not feel weak. If the immunity system does not function well, then the person can succumb to even the slightest of the disease-causing pathogens because it will not be able to shield the body from the effect of the pathogen. The study of this defense mechanism, known as allergy and immunology has led to the foundation of the treatment of the diseases that were at first thought to be uncontrollable. The researcher or the people involved in the research of the immunity disorders or the allergies and their cures are termed as the immunologists and the study is known as allergy and immunology . This is an emerging field in medical research and is being taken up as a career by plenty of candidates.
Doctors specializing in immunology deal with issues related to the immune system. A physician who specializes in immunology diagnoses and treats a wide range of diseases. If you would prefer to work with autoimmune diseases or infectious diseases, you can choose to specialize. Specializing in dealing with the immune system, immunologists may sometimes work as a member of a team assessing how the immune system may react to different treatments.
