Active immunity. Active immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Active immunity can be acquired through natural immunity or vaccine-induced immunity.
Adaptive immunity, also known as acquired immunity, is the third line of defense and, whilst slower to act, protects an organism from specific pathogens. Adaptive immunity can be further classified into two subgroups: active immunity and passive immunity.
Active immunity occurs when you make antibodies, while passive immunity is when you are given antibodies. Active and passive immunity are two fundamental types of immune responses that our bodies use to fight off diseases and infections.
Active immunity and passive immunity are the two types of acquired immunity. Active immunity is the most common type. It develops in response to an infection or vaccination. These methods...
Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else. Both of these different types of immunity can be acquired in different ways.
During artificially acquired active immunity, one is immunized with one or more of the following: attenuated microbes, killed organisms, fragmented microorganisms, or antigens produced by recombinant DNA technology, or toxoids.
As opposed to passive immunity, where antibodies are injected into an organism during pregnancy or they are artificially acquired, active immunity requires a process of training immune cells to recognize and counteract foreign bodies.
