adoptive immunity
C1/C2Technical/Scientific
Definition
Meaning
Immunity acquired by receiving ready-made immune cells or antibodies from another individual, rather than through one's own immune response.
A state of temporary or long-term immune protection resulting from the transfer of immune components (like T cells, antibodies, or memory cells) from a donor to a recipient. This is distinct from active immunity, which the body generates itself. Examples include immunity from mother to fetus, therapeutic cell transfers, or some forms of vaccination.
Linguistics
Semantic Notes
This is a specialized term in immunology and medicine. Often contrasted with 'active immunity' and 'innate immunity'. 'Adoptive' in this context refers to the 'adoption' of external immune components by the recipient's body.

Context Usage
Academic
The primary domain. Used in research papers, textbooks, and lectures on immunology, virology, and cell therapy. E.g., 'The study demonstrated durable adoptive immunity against the tumour.'
Everyday
Virtually never used in everyday conversation.
Technical
Used by medical professionals, researchers, and in clinical settings discussing immunotherapies, transplant immunology, and maternal-fetal medicine.
Examples
By Part of Speech
verb
British English
- The treatment aims to adoptively transfer immunity to the patient.
- The cells were adoptively transferred.
American English
- The therapy adoptively confers immunity to the recipient.
- Researchers adoptively immunized the mice.
adjective
British English
- The adoptive immune response was carefully monitored.
- They studied adoptive T-cell therapies.
American English
- The patient showed signs of adoptive immune protection.
- Adoptive immunotherapy is a promising field.
Examples
By CEFR Level
- Newborns have some adoptive immunity from their mothers.
- Adoptive immunity does not create long-lasting memory in the recipient.
- The clinical trial focused on using adoptive immunity to treat resistant infections.
- Unlike a vaccine, this approach establishes adoptive immunity by directly infusing engineered lymphocytes.
- A key challenge in adoptive immunity is preventing the host from rejecting the transferred cells.
Learning
Memory Aids
Mnemonic
Think of 'adopting' a child—you receive a child who was made by someone else. Similarly, in 'adoptive immunity', your body receives immune cells or antibodies that were 'made' by someone (or something) else.
Conceptual Metaphor
IMMUNITY IS A TRANSFERABLE COMMODITY / IMMUNE DEFENCE IS A GIFT.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'адаптивный иммунитет' (adaptive immunity), which is a broader term referring to the body's specific, learned immune response. 'Adoptive immunity' is a specific subset of this, involving transfer. The correct Russian translation is typically 'адоптивный иммунитет' or 'пассивный клеточный иммунитет'.
Common Mistakes
- Confusing 'adoptive' with 'adaptive'. 'Adaptive immunity' is the system that learns; 'adoptive immunity' is a type of transfer within it. Incorrect: 'Vaccines provide adoptive immunity.' (They typically stimulate active immunity).

FAQ
Frequently Asked Questions
'Adaptive immunity' is the broader system of specific, learned immune responses (involving B cells and T cells). 'Adoptive immunity' is a specific type of adaptive immunity where these learned cells (or their products) are transferred from one individual to another.
Typically, it is not permanent unless the transferred cells persist long-term in the recipient. It often provides temporary protection, as the transferred cells have a limited lifespan and are not constantly regenerated by the recipient's own body.
Standard vaccines are designed to stimulate 'active immunity', where your own body learns to make the response. However, some advanced immunotherapies (like certain cancer treatments) involve extracting, modifying, and re-infusing a patient's own cells, which is a form of autologous adoptive immunity.
A baby receiving antibodies from its mother through the placenta (before birth) or through breast milk (after birth) is a natural example. A medical example is CAR-T cell therapy, where a patient's T cells are genetically engineered to fight cancer and then transferred back into the patient.
