Questions and Answers
How does artificially acquired active immunity differ from naturally acquired active immunity?
How does artificially acquired active immunity differ from naturally acquired active immunity?
- Artificially acquired active immunity involves receiving pre-made antibodies.
- Artificially acquired active immunity results in no immunological memory.
- Naturally acquired active immunity requires injection of antibodies from another person or animal.
- Naturally acquired active immunity involves exposure to a pathogen in the environment, while artificially acquired active immunity involves exposure through artificial means, such as vaccination. (correct)
Why is artificially acquired passive immunity used when there is not enough time for the body to create its own antibodies?
Why is artificially acquired passive immunity used when there is not enough time for the body to create its own antibodies?
- Artificially acquired passive immunity only works in conjunction with active immunity.
- Artificially acquired passive immunity has a longer-lasting effect compared to active immunity.
- Artificially acquired passive immunity provides immediate protection by directly introducing antibodies. (correct)
- Artificially acquired passive immunity stimulates the body to produce antibodies faster.

Adaptive Immunity
Adaptive Immunity
Specific immunity that creates immunological memory to pathogens.
Active Immunity
Active Immunity
Immunity gained by producing antibodies after exposure to an antigen.

Study Notes
- Adaptive immunity is specific and creates immunological memory to pathogens
- Immunological memory is acquired through four different ways, categorized into active and passive processes
Active Immunity
- Involves the body creating its own antibodies against a pathogen
- Includes naturally acquired and artificially acquired immunity
Naturally Acquired Active Immunity
- Occurs when the body encounters a pathogen in the environment and mounts an immune response
- Results in the creation of antibodies and immunological memory against the specific infection
Artificially Acquired Active Immunity
- Involves exposure to a pathogen through artificial means, such as vaccination
- The body creates antibodies against the pathogen, leading to immunological memory
- Example: Polio vaccine exposes individuals to an inactivated form of the virus, enabling the body to create antibodies and prevent the disease
Passive Immunity
- Involves receiving pre-made antibodies rather than creating them
- Includes naturally acquired and artificially acquired immunity
- Natural sources mean it is coming from environmental/bodily sources
Naturally Acquired Passive Immunity
- Involves receiving antibodies through breast milk or maternal antibodies
- Maternal antibodies help protect infants who cannot mount their own immunological defenses
Artificially Acquired Passive Immunity
- Involves receiving antibodies produced in another person or animal via blood plasma or serum
- Used when there is not enough time for the body to create its own antibodies
- Example: Post-prophylactic injection of antibodies for suspected rabies contraction to fight off the infection
- Monoclonal antibodies are obtained from a person or animal
