Question

What is active and passive immunity?

Hint:

Remember: Active immunity lasts longer and requires antigen exposure; passive immunity is immediate but short-lived.

Answer 1

Active immunity: Immunity developed by the body after exposure to a pathogen or vaccination.
Passive immunity: Immunity acquired through the transfer of antibodies from another source, such as mother's milk or antibody injections. Active immunity provides long-term protection by stimulating the immune system, whereas passive immunity provides immediate but temporary protection without activating the immune system.
