What is natural immunity?
Immunity that has been developed without medical intervention
What is artificial immunity?
Immunity that has been developed via medical intervention
Natural active?
- Getting sick
- Provides long term immunity
Exposure to pathogen is not deliberate
Natural passive?
- Recieving antibodies from mother during breast feeding
- Provides short term immunity
No memory cells are produced
Artificial active?
- Vaccinations
- Long term immunity
Your body makes the antibodies
Artificial passive?
- Being administered antibodies
- Antibodies provide short term immunity
No memory cells are produced
A person bitten by an animal with rabies should be given an injection of specific antibodies, what type of immunity is this?
Artificial passive
What is a vaccine?
A solution containing antigens that artificially stimulate an immune response
Cell mediated response is NOT stimulated by vaccines
Effective vaccines
- Contains the specific antigen from disease
- Stimulation of B cells
Vaccinations become effective after a few weeks
True
This gives time for the immune system to produce B memory cells
Infectious disease
Illness caused by a pathogen
Non-infectious disease
An illness not caused by a pathogen
Emerging disease
Diseases that have not occured in humans before
Typically from animals
Re-emerging disease
Diseases that were once a public health problem, but declined.
Could be because pathogen has evolved or decreased vaccination rates
