Defence Against Infections Flashcards
The adaptive immune response is mediated by what cells?
B and T lymphocytes
What is active immunisation?
Causing a state of immunological readiness such that the first infection was a given pathogen is recognised during the second infection. Requires active immune response involving B and T cells
What is passive immunisation?
Transfer preformed immunological mediators (antibodies) to generate a state of enhanced immunity
Give examples of infections for which vaccination has been successful
Smallpox Diptheria Measles Mumps Pertussis Polio Rubella Tetanus
Is Tetanus actively or passively immunised against?
Passive
Is Gangrene actively or passively immunised against?
Passive
Is Snakebite actively or passively immunised against?

Active immunisation can be divided into what two groups?
Attenuated (live)
Inactivated (dead)

Active
Is Rabies actively or passively immunised against?
Passive
Is Yellow fever actively or passively immunised against?
Active
Why was Smallpox successfully eradicated?
- Exclusive to humans (no animal reservoir)
- No hidden carriers (obvious disease)
- Only one serotype
- Vaccination were 100% successful
