Antibodies can also be passed from one organism to another. Difference: Passive Immunity involves an individual containing antibodies that were not produced by that individual (i.e comes from an external source). Passive immunity is the type of adaptive immunity that does not need to be in direct contact with the bacteria, pathogen or any other harmful foreign elements to provide resistance.
