Passive immunity
Understand the Problem
The question is asking about passive immunity, which refers to the immunity gained through the transfer of antibodies from one individual to another. This typically occurs naturally, such as from mother to child during breastfeeding, or can be administered artificially through antibody-containing blood products.
Answer
Passive immunity involves receiving antibodies directly, providing immediate but short-lived protection.
Passive immunity is when a person is given pre-formed antibodies for immediate protection. It occurs naturally when maternal antibodies are passed to a baby through the placenta or breast milk. This type of immunity provides immediate but not long-lasting protection.

More Information
Passive immunity provides immediate protection by the transfer of antibodies from another source. It is natural in newborns but can also be medically administered in cases of exposure to specific diseases.
Tips
Confusing passive immunity with active immunity, which involves the body's own immune response to an antigen, is a common mistake.
