IMMUNOLOGY

Detailed explanation-1: -However, passive immunity is short term, unlike active immunity which is long-lasting. That’s because, in passive immunity, the antibodies are borrowed from another person and not continuously replenished as it is in active immunity.

Detailed explanation-2: -In passive immunization a person receives antibodies or lymphocytes that have been produced by another individual’s immune system; in active immunization the individual’s own immune system is stimulated to produce antibodies and lymphocytes.

Detailed explanation-3: -Passive immunity provides short-term protection against infection. Antibodies are proteins that bind to and help attack pathogens, such as bacteria and viruses. They are a key component of the human immune system. Typically, antibodies are produced by white blood cells in response to infection.
