Principles and Methods of Artificial Immune System Vaccination of Learning Systems

If you create an account, you can set up a personal learning profile on the site. Artificially acquired active immunity is protection produced by intentional exposure of a person to antigens in a vaccine, so as to produce an active and lasting immune response. The antigens in the vaccine stimulate the immune system to produce antibodies and memory cells which are specifically directed against the antigens in the vaccine. The memory cells generate a rapid immune response from the rest of the immune system, and the infectious agents are quickly attacked and destroyed, often before symptoms of the disease can develop. Some vaccines are given as a single dose, but others are given as a course of three doses at intervals of a few weeks. This is necessary to increase the immune response and ensure an adequate level of protection.

Fundamentals of Vaccine Immunology

Our body has evolved a complex system to combat viruses and other pathogens. Computing researchers have started paying increasing attention to natural immune systems because of their ability to learn how to distinguish between pathogens and non-pathogens using immunoglobulins, antibodies and memory cells. There are now several artificial immune system algorithms for learning inspired by the human natural immune system. Once the body gains immunity to a specific disease it generally remains free from it almost for life. One way to build such immunity is through vaccination. Vaccination is a process of stimulating the immune system by using a weaker infectious agent or extracting proteins from an infectious agent.

Abstract Immunity is the state of protection against infectious disease conferred either through an immune response generated by immunization or previous infection or by other non-immunological factors. The first article of this series reviewed those host mechanisms that protect against microbial invasion. Both limited effectiveness against particular pathogens together with pathogen evasion processes mean that certain infectious diseases are still a frequent occurrence; some are occupationally related with the risk to health care workers being particularly well documented [ 1 , 2 ]. Since particular occupationally transmitted infections can be prevented by immunization, this article will look at how the different vaccine types modulate adaptive responses to provide further protection. First, however, the terms active and passive immunity will be considered.

Naturally acquired active immunity occurs when a person is exposed to a live pathogen, develops the disease, and then develops immunity. Immunity is the state of protection against infectious disease conferred either through an immune response generated by immunization or previous infection, or by other non-immunological factors. There are two ways to acquire active resistance against invading microbes: active natural and active artificial. Typhoid vaccination : Immunization commonly referred to as vaccination is the deliberate induction of an immune response, and represents the single most effective manipulation of the immune system that scientists have developed. Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response.

Naturally Acquired Passive Immunity — involves a natural transfer of antibodies from a mother to her infant. Acquired immunity: Immunity acquired by infection or vaccination active immunity or by the transfer of antibody or lymphocytes from an immune donor passive immunity. It is present before the … It is also known as adaptive immunity. For example humans have innate immunity against distemper, a fatal disease of dogs.
