Active immunity last longer than passive immunity.

Question

Quizplus · Accepted Answer

Active immunity is acquired through the body's own immune response, such as from exposure to a pathogen or through vaccination. The immune response produces memory cells that can quickly recognize and fight off the pathogen if it is encountered again in the future. This means that active immunity can last a long time, even for a lifetime in some cases. Passive immunity, on the other hand, is acquired through the transfer of antibodies from another source, such as a mother's breast milk or an injection of pre-formed antibodies. This type of immunity does not produce memory cells and therefore does not last as long as active immunity.
