What is the mechanism of artificial immunity?

The mechanism of artificial immunity involves the introduction of antibodies into the body, which can occur through vaccinations or antibody therapies. This form of immunity is not generated by the individual's immune system but rather supplied directly, allowing the body to defend against specific pathogens without having to produce the antibodies itself.

For example, in the case of passive immunity, antibodies derived from another source (such as serum from animals or humans who have already developed immunity) are injected into a person. This process provides immediate, temporary protection against disease, highlighting the role of externally introduced antibodies in establishing artificial immunity. Understanding this mechanism is crucial for grasping how vaccinations work or how certain treatments can confer immunity without the need for the body to actively engage its own immune response.
