Vaccination Principles

Vaccination Principles

Vaccinations stimulate the immune system to produce antibodies without causing the disease, providing active artificial immunity.

Types of Immunity

  • Active Immunity: Body produces its own antibodies (vaccines or infection).
  • Passive Immunity: Temporary protection through pre-formed antibodies (e.g., immunoglobulin or breast milk).
  • Herd Immunity: Sufficient population immunity to stop disease spread.
