Question 1

What is a vaccine

Answer 1

Vaccines contain small amounts of weakened or dead versions of a pathogen. They are inserted into your body usually by an injection. The vaccination causes your lymphocyte to produce antibodies to the pathogen.

Question 2

How does this improve the response to pathogens

Answer 2

If you later encounter the real pathogen your body can respond more quickly than if you had not been vaccinated. Removing disease causing microorganisms before they cause disease.
