Answer 2

Hi dude

here's ur answer...

To understand how vaccines work, it helps to look first at how the immune system works, because vaccines harness the natural activity of your immune system..

A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria..
