Study Notes
Passive Immunity
- Antibodies are received from an external source
- The body does not produce the antibodies itself
- Examples of passive immunity include receiving antibodies from a mother through breast milk or through an injection of antibodies
Active Immunity
- The body produces its own antibodies
- Occurs after exposure to a pathogen or vaccination
- Provides long-term protection against a specific disease
Natural Immunity
- Antibody production or pathogen encounter occurs naturally
- This process can be acquired through exposure to a pathogen in the environment or through inheritance from a parent
Artificial Immunity
- Antibody production or pathogen encounter occurs through medical intervention
- Involves the deliberate introduction of a pathogen or a substance that stimulates the immune response
- Examples of artificial immunity include vaccinations and immune globulin injections
Types of Immunity
- Passive Immunity: Antibodies are received from an external source. The individual's immune system does not produce them.
- Active Immunity: The individual's immune system produces antibodies in response to an antigen exposure.
- Natural Immunity: Antibody production or pathogen exposure happens naturally, without medical intervention.
- Artificial Immunity: Antibody production or pathogen exposure is induced by a medical source, such as a vaccine or immune serum.
Example: Immunity in Infants
- Passive, Natural Immunity: A baby receiving antibodies from the mother’s breast milk is a prime example of this type of immunity. The antibodies were not generated by the baby's immune system, but rather transferred from the mother through natural means.
