Vaccines are made of mixtures that contain either parts of pathogens or whole pathogens that prepare the body's defenses to fight against the pathogens.

Answer from: Lalagrl

A vaccine is a substance that helps protect against a particular infection. The body fights infections using the immune system. Each vaccine contains a small amount of the disease germ (virus or bacteria) or parts of the germ. For examples are the measles virus and pertussis (whooping cough) bacteria.
