'''Immunity''' refers to the ability of an organism to resist or eliminate potentially harmful foreign materials or abnormal cells that may threaten its health. This complex biological system involves a variety of cells, organs, proteins, and tissues which work in concert to defend the body against pathogens, including viruses, bacteria, and parasites. Immunity can be categorized into two main types: [[innate immunity]] and [[adaptive immunity]].
{{DISPLAYTITLE:On Immunity: An Inoculation}}


== Innate Immunity ==
==Overview==
Innate immunity, also known as nonspecific immunity, is the first line of defense and operates to prevent the entry of pathogens into the body or to eliminate them before they can cause disease. It includes physical barriers such as the skin and mucous membranes, chemical barriers like stomach acid, and cellular defenses involving a variety of cells (e.g., [[phagocytes]], [[natural killer cells]]). Innate immune responses are not specific to a particular pathogen and do not confer long-lasting immunity.

Published in 2014, the book delves into the fears and myths surrounding vaccines, drawing connections between personal health decisions and broader societal implications.


== Adaptive Immunity ==
[[File:On Immunity An Inoculation.jpg|thumb|right|Cover of ''On Immunity: An Inoculation'']]
Adaptive immunity, or specific immunity, involves the development of immunity as a response to the exposure to a pathogen. Unlike innate immunity, adaptive immunity is highly specific to the particular pathogen that induced it and involves memory, which results in an enhanced response to subsequent exposures to that pathogen. Adaptive immunity is mediated by two types of lymphocytes: [[B cells]] (which produce antibodies) and [[T cells]] (which can kill infected cells directly or help in the activation of other immune cells).


== Active and Passive Immunity ==
==Themes==
Active immunity results from the exposure to a disease-causing agent, leading to the production of a specific immune response and memory cells. This can occur naturally through infection or can be induced artificially through vaccination. Passive immunity, on the other hand, is the transfer of antibodies from one individual to another, as occurs naturally from mother to fetus through the placenta or can be induced artificially by injecting antibodies. While passive immunity provides immediate protection, it is temporary, as the antibodies are eventually degraded.
''On Immunity'' addresses several key themes, including the concept of [[herd immunity]], the history of [[vaccination]], and the role of [[public health]] in society. Biss examines how [[immunization]] is not just a personal choice but a communal responsibility, emphasizing the interconnectedness of individuals within a community.


== Herd Immunity ==
===Herd Immunity===
[[Herd immunity]] occurs when a significant portion of a population becomes immune to an infectious disease, thereby providing a measure of protection for individuals who are not immune. Herd immunity can limit the spread of contagious diseases and is a key concept in the field of epidemiology and vaccination strategies.
[[Herd immunity]] is a central theme in the book, highlighting how the immunity of a population can protect those who are unable to be vaccinated, such as infants and individuals with compromised immune systems. Biss discusses how achieving herd immunity requires a high percentage of the population to be vaccinated, thus preventing the spread of infectious diseases.


== Autoimmunity ==
===Cultural Perceptions===
Autoimmunity is a condition in which the immune system mistakenly attacks the body's own cells, leading to autoimmune diseases such as [[rheumatoid arthritis]], [[type 1 diabetes]], and [[systemic lupus erythematosus]]. The exact causes of autoimmunity are not fully understood, but they are thought to involve a combination of genetic, environmental, and hormonal factors.
Biss explores the cultural perceptions and misconceptions about vaccines, including the fear of [[vaccine side effects]] and the influence of [[anti-vaccine movements]]. She analyzes how these perceptions are shaped by historical events, media portrayals, and personal anecdotes.


== Immunodeficiency ==
==Historical Context==
Immunodeficiency occurs when one or more components of the immune system are deficient or absent, leading to an increased susceptibility to infections. Immunodeficiency can be primary (congenital) or acquired, with the most well-known acquired immunodeficiency syndrome (AIDS) being caused by the human immunodeficiency virus (HIV).
The book provides a historical overview of vaccination, tracing its origins from the early practice of [[variolation]] to the development of modern vaccines. Biss discusses key figures in the history of vaccination, such as [[Edward Jenner]], who pioneered the smallpox vaccine, and [[Louis Pasteur]], who developed vaccines for rabies and anthrax.


== Immunization ==
==Public Health and Policy==
[[Immunization]] is the process by which an individual's immune system becomes fortified against an agent (known as the immunogen). Vaccination is one of the most effective methods of preventing infectious diseases; widespread immunization has led to the eradication or significant control of diseases such as smallpox, polio, and measles in many parts of the world.
Biss examines the role of public health policy in promoting vaccination and protecting public health. She discusses the challenges faced by public health officials in combating misinformation and increasing vaccine uptake. The book also addresses the ethical considerations of mandatory vaccination policies and the balance between individual rights and community health.


== Conclusion ==
==Personal Narrative==
The immune system plays a crucial role in maintaining health and combating infections. Understanding the mechanisms of immunity and the factors that can compromise it is essential for the development of effective treatments and preventive measures against infectious diseases.
Interwoven with the factual content, Biss includes personal narratives and reflections on her own experiences as a mother making vaccination decisions for her child. These narratives provide a human perspective on the complex issues surrounding vaccination and immunity.
