conferred when a disease or an immunization triggers production of an antibody or antitoxin (also active immunization).
the production of antibodies against a specific disease by the immune system. Active immunity can be acquired in two ways, either by contracting the disease or through vaccination. Active immunity is usually permanent, meaning an individual is protected from the disease for the duration of their lives.
Immunity acquired after stimulation with an antigen by natural infection or other exposure.
Protection from a disease as a result of previous exposure to the disease-causing infectious agent or antigen. The protection can be a result of having had the disease or having received a vaccine to prevent getting the disease.
a type of acquired immunity where the body produces antibodies after infection or vaccination.
Resistance resulting from previous exposure to an infectious agent or antigen may be active and specific, as a result of naturally acquired infection or intentional vaccination (artificial active immunity), or it may be passive immunity.
Immunity gained by direct exposure to antigens followed by antibody production.
immunity naturally produced by the body's own immune system in response to stimulation by foreign antigens. Contrast with passive immunity.
a form of acquired immunity in which the body produces its own antibodies against disease-causing antigens
immunity developed by an individual organism as a consequence of its own exposure to an infecting organism, biochemical structure, or large molecule (compare ‘passive immunity’)
a resistance of the body to infection in which the host produces its own antibodies in response to natural or artificial antigens
Immunity generated by an organism's production of antibodies and cytokines. 798
Immunity produced when an animalâ€™s own immune system reacts to a stimulus e.g., a virus or bacteria, and produces antibodies and cells which will protect it from the disease caused by the bacteria or virus. Compare with 'passive immunity.'
Immunity produced by the person’s own immune system. This type of immunity can be brought about by a natural infection or by a vaccine. It is usually long lasting. (Compare with passive immunity.)
A type of acquired immunity whereby resistance to a disease is built up by either having the disease or receiving a vaccine against it.
Immunity that is elicited by natural exposure to a pathogen or foreign substance or by vaccination.
The ability, obtained during the life of an individual, to produce specific antibodies or T cells.
active immunity is generated by the body when the immune system is triggered to produce antibodies, either by immunisation or by disease.
Immunity produced by the body in response to stimulation by a disease-causing organism or a vaccine.
