Who coined the term immunology and won a Nobel Prize for it?

Questions about Immunology
Short answers, pulled from the story.
What is immunology the study of?
Immunology is a branch of biology and medicine that covers the study of immune systems in all organisms. It charts, measures, and contextualizes the functioning of the immune system in health and disease, including immunological disorders such as autoimmune diseases, hypersensitivities, immune deficiency, and transplant rejection.
What is the earliest written mention of immunity in immunology?
The earliest written mention of immunity traces back to the plague of Athens in 430 BCE. Thucydides noted that people who had recovered from the disease could nurse the sick without contracting it a second time.
What is the difference between the cellular and humoral theories of immunity?
The cellular theory of immunity, represented by Elie Metchnikoff, held that cells, more precisely phagocytes, were responsible for immune responses. The humoral theory, held by Robert Koch and Emil von Behring among others, stated that the active immune agents were soluble molecules in the organism's humors rather than its cells.
Why are newborns considered to be in a state of physiological immunodeficiency?
Neonates are in a state of physiological immunodeficiency because both their innate and adaptive immune responses are greatly suppressed. Their phagocytic activity is impaired, their T cells proliferate poorly, and the mean level of C3 in a newborn is approximately 65 percent of the adult level.
What is behavioural immunity in immunology?
Behavioural immunity, a phrase coined by Mark Schaller, refers to psychological pathogen avoidance drivers, such as disgust aroused by stimuli encountered around pathogen-infected individuals, including the smell of vomit. It falls within ecoimmunology, which explores the relationship between an organism's immune system and its environment.
What diseases does clinical immunology and immunotherapy treat?
Clinical immunology studies immunodeficiencies such as chronic granulomatous disease and autoimmune conditions such as systemic lupus erythematosus, rheumatoid arthritis, Hashimoto's disease, and myasthenia gravis. Immunotherapy is most commonly used to treat allergies, autoimmune disorders like Crohn's disease, certain cancers, and patients who are immunosuppressed, such as those with HIV.
