Global Disease Elimination Progress

  • Eradicated: Smallpox (1980)
  • Near elimination: Polio (99.9% reduction since 1988)
  • Dramatically reduced: Measles, mumps, rubella, diphtheria, tetanus

Quick Recall Flashcards

What is a vaccine and how does it work?
A vaccine contains a dead or weakened form of a pathogen (or its antigens). It triggers the immune system to produce antibodies and memory cells without causing disease. If the real pathogen enters later, memory cells respond rapidly.
Why don't vaccines cause the disease they protect against?
Vaccines use dead or inactive pathogens, or just antigens from the pathogen's surface. The pathogen cannot multiply or cause infection. The immune system still recognises the antigens and builds immunity.
