A nurse gives a patient an injection of immune globulin after a possible exposure. Which kind of immunity does this provide?

1. Immunity is active when the individual develops an immune response of their own, and passive when immune components are transferred in from someone else. 2. Each of those two can arise naturally or artificially. 3. Injections of immunoglobulins, taken from animals previously exposed to a specific pathogen, hand over ready-made antibodies, so the immunity is passive. 4. Because it is given as a medical treatment rather than picked up by living, it is artificially acquired passive immunity. 5. A vaccine would be artificially acquired active immunity, since the patient still builds their own response and their own memory. 6. The downside here is that no immunological memory develops and the transferred antibodies are effective only until they degrade. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 21 "The Lymphatic and Immune System", section 21.4 The Adaptive Immune Response: B-lymphocytes and Antibodies_
