Verified step by step guidance1
Understand the concept of immunity: Immunity is the body's ability to resist or eliminate potentially harmful foreign materials or abnormal cells.
Differentiate between active and passive immunity: Active immunity involves the production of antibodies by the immune system in response to the presence of an antigen, while passive immunity involves the transfer of antibodies from another source.
Differentiate between natural and artificial immunity: Natural immunity occurs through natural exposure to a pathogen, while artificial immunity is acquired through medical intervention, such as vaccination.
Identify the type of immunity established by vaccination: Vaccination introduces a harmless form of an antigen to stimulate the body's immune response, leading to the production of antibodies and memory cells without causing disease.
Conclude that vaccination establishes artificial active immunity: Since the immune response is actively generated by the body in response to an artificial introduction of an antigen, the immunity is classified as artificial active immunity.
