  "term": "Acquired immunity",
  "field": "Oncology and biomedicine",
  "definition": "A type of immunity that develops when a person’s immune system responds to a foreign substance or microorganism, or that occurs after a person receives antibodies from another source. The two types of acquired immunity are adaptive and passive. Adaptive immunity occurs in response to being infected with or vaccinated against a microorganism. The body makes an immune response, which can prevent future infection with the microorganism. Passive immunity occurs when a person receives antibodies to a disease or toxin rather than making them through his or her own immune system.",
