Passive immunity generally lasts longer than active immunity.

Question

Quizplus · Accepted Answer

Passive immunity is a temporary immunity that is acquired through the transfer of antibodies from another source, such as through breastfeeding or injection of immunoglobulins. This immunity gradually decreases over time and eventually fades away. On the other hand, active immunity is a long-lasting immunity that is acquired through the production of antibodies by the immune system in response to exposure to a pathogen or vaccine. This immunity may last for years or even a lifetime. Therefore, passive immunity does not last longer than active immunity, and in fact, it is often shorter-lived.
