When the body is able to make its own antibodies by having disease & recovering or by vaccination, it is known as?
Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2015
Explanation
- Active immunity is the resistance developed by an individual's own immune system.
- This process is initiated either by recovering from a natural infection or through artificial means like vaccination.
- The key feature is the production of specific antibodies and the formation of immunological memory by the host's body.
- This memory allows for a faster and stronger response to future exposures to the same pathogen.
Why Other Options Were Wrong
- Option A: Acquired immunity is a very broad term that includes both active and passive immunity. The question describes a specific type of acquired immunity.
- Option B: Passive immunity involves receiving pre-made antibodies from another source, not producing them. The question explicitly states the body is 'making its own antibodies'.
- Option D: Passive acquired immunity is synonymous with passive immunity. It involves the transfer of ready-made antibodies, which is the opposite of the process described in the question.

Clinical Relevance
- Nursing practice connection: Knowing Types of Immunity helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
- Understanding the difference between active and passive immunity is fundamental for nurses in patient education, especially regarding vaccination schedules and benefits.
- Nurses administer vaccines (artificial active immunity) and sometimes immunoglobulins (artificial passive immunity), so they must know the onset, duration, and purpose of each.
- What if a patient who is immunocompromised is exposed to measles? They cannot mount an effective active immune response. The appropriate action would be to administer measles immunoglobulin (artificial passive immunity) for immediate protection.
How to Approach the Question
- First, analyze the question's keywords: 'make its own antibodies', 'having disease & recovering', 'vaccination'.
- These keywords point to a process where the body is actively involved in creating its own defense.
- Define the options. 'Active' implies the body is doing the work. 'Passive' implies the body is receiving help.
- Evaluate 'Active immunity': This matches the description perfectly, as it's triggered by infection or vaccination, leading to the body producing its own antibodies.
- Evaluate 'Passive immunity': This is the opposite; it involves receiving antibodies, so it's incorrect.
- Evaluate 'Acquired immunity': This is a general category. Since a more specific and accurate option ('Active immunity') is available, choose that one.
