What is the primary purpose of vaccines?

Explanation:
Vaccines train the immune system to respond quickly and effectively to real pathogens by exposing the body to an antigen. This builds immune memory so that, if the person later encounters the actual pathogen, the immune response is rapid and strong enough to prevent illness or greatly lessen its severity. The goal is prevention, not treatment of an active infection, and vaccines do not increase susceptibility nor cure chronic diseases. For example, after vaccination, your immune system recognizes the pathogen faster the next time and can stop it from causing significant illness.
