Definition of Vaccine

A vaccine is a medicine that helps you to fight disease-causing germs. Doctors give you these medicines well in advance so that when your body comes face to face with the dangerous germs it can fight them.

How do Vaccines Work?

  • A vaccine contains a little bit of a disease-causing germ that is weak or dead. Since the germ has been killed or weakened before it is used to make the vaccine, it does not make the person sick.
  • When a person receives a vaccine, the body’s defense system jumps into action and reacts strongly by making antibodies.
  • The army of antibodies then helps to trap and kill the harmful germs that could lead to disease.
