Passive immunity means that you gained resistance to the disease without having to actively do anything to gain resistance.

Explanation:

  1. When maternal antibodies are transferred to the fetus through the placenta (occurs naturally).

  2. When high levels of human antibodies specific for a pathogen or toxin are transferred to non-immune individuals (artificially induced).
