What type of immunity results from the transfer of antibodies from another individual?

The correct choice is passive immunity, which is characterized by the transfer of pre-formed antibodies from one individual to another. This type of immunity does not involve the recipient's immune system actively producing its own antibodies. Instead, the antibodies are acquired from an external source, such as through breastfeeding, where a mother passes antibodies to her infant, or through medical interventions like immunoglobulin therapy.

Passive immunity provides immediate protection against pathogens but is temporary, lasting only for a short duration because the recipient's body does not develop memory cells or long-term immunity. This is in contrast to active immunity, where exposure to an antigen triggers the immune system to produce its own antibodies and memory cells, leading to long-lasting protection. Natural immunity involves the body’s immune response to infections acquired through exposure to pathogens, while artificial immunity typically refers to immunizations that also stimulate active immunity through exposure to attenuated or inactivated pathogens.
