  • Recognize the virus, bacteria, or germ that invades your body 
  • Build resistance for specific conditions and strengthen your immune system 
  • Produce antibodies to fight the disease 
  • Memorize the disease as well as how to fight it 

In this way, your protection against a disease can last from anywhere between years, decades, or lifetime.
