passive immunity is short term

it could either be from a mom giving the antibodies from her blood to the baby in her womb, and when the baby gets out, it still has some of the anitbodies to protect it (for a couple days/ months/ years)

or

antibodies are injected into a person (this is not a vaccine) to help cure the illness (rabies is an example of a disease where people inject the antibodies)
