- Innate immunity. The 'innate' (meaning: present from birth) part of the immune system is so-called because it has a number of set strategies for recognising and dealing with certain kinds of infection, without needing to be trained to identify them.he 'innate' (meaning: present from birth) part of the immune system is so-called because it has a number of set strategies for recognising and dealing with certain kinds of infection, without needing to be trained to identify them.

Vaccine A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.he effectiveness of vaccination has been widely studied and verified; for example, the influenza vaccine, the HPV vaccine, and the chicken pox vaccine.

Legal immunity From Wikipedia, the free encyclopedia. (Redirected from Immunity from prosecution) Legal immunity, or immunity from prosecution, is a legal status wherein an individual or entity can not be held liable for a violation of the law to facilitate societal aims that outweigh the value of imposing liability in such cases. Such legal immunity may be from criminal prosecution or from civil liability (being subject of lawsuit) or both.

- en españolTu sistema inmunológico. To be immune (say: ih-MYOON) means to be protected. So it makes sense that the body system that helps fight off sickness is called the immune system. The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. White blood cells, also called leukocytes (say: LOO-kuh-sytes), are part of this defense system.

Adaptive Immunity Adaptive Immunity Definition. Adaptive immunity is an important part of the immune system. It is protection from an infectious disease agent that is mediated by B-and T-lymphocytes following exposure to specific antigen, and characterized by immunological memory.ell-mediated immunity does not involve antibodies but rather involves the activation of macrophages, natural killer cells (NK), antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

Vaccination Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual's immune system to develop adaptive immunity to a pathogen. Vaccines can prevent or ameliorate morbidity from infection. When a sufficiently large percentage of a population has been vaccinated, this results in herd immunity.

What is Immunity? Active or passive immune protection is determined by the way in which the protection is conferred. Protection that is active is conferred by contact with an infectious organism or a vaccine. This provokes an active immune response in the person who comes into contact with the organism.

How does the body fight off a virus? Once the virus has been cleared, a small number of these specialist B and T cells persist and retain an accurate memory of the destroyed virus. This means our immune systems are primed to prevent another infection from the same virus, without attacking the body's own cells by accident. This is known as 'acquired immunity'. Having a single infection with mumps during childhood will give you lifelong resistance, for example.

Acquired immunity is in contrast to innate immunity (natural immunity).

Active Immunity: Active Immunity: Active immunity is immunity that develops as a result of natural or deliberate exposure to an antigen. A vaccination is an example of active immunity. Vaccinations stimulate the immune system with an antigen.The immune system then produces B and T cells that quicken and strengthen the body's response to repeated infection. This is an example of passive immunity because it artificially exposes the immune system to weak or dead pathogens for a sickness or a disease.In response to this, the immune system uses antibodies to kill and build up an immunity to the disease or sickness injected into the body through a vaccination.ctive Immunity: Active immunity is immunity that develops as a result of natural or deliberate exposure to an antigen. A vaccination is an example of active immunity. Vaccinations stimulate the immune system with an antigen.

Immune system The immune system is a system of many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue.he principle behind vaccination (also called immunization) is to introduce an antigen from a pathogen in order to stimulate the immune system and develop specific immunity against that particular pathogen without causing disease associated with that organism.
