AP BIOLOGY

Detailed explanation-1: -The major advantage to passive immunity is that protection is immediate, whereas active immunity takes time (usually several weeks) to develop. However, passive immunity lasts only for a few weeks or months. Only active immunity is long-lasting.

Detailed explanation-2: -Unlike active immunity, passive immunity provides immediate protection. But that protection is generally short-lived, as the supply of antibodies is not being replenished like they would be in someone whose own immune system was generating them.

Detailed explanation-3: -A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one’s own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body.

Detailed explanation-4: -Unlike active immunity, passive immunity is short-lived (often only for a few months), because it does not involve the production and upkeep of memory cells.

Detailed explanation-5: -A type of immunity that occurs when a person is given antibodies rather than making them through his or her own immune system. For example, passive immunity occurs when a baby receives a mother’s antibodies through the placenta or breast milk.
