Vaccination is a process of injecting a dead or weakened form of a pathogen into the body. How does this help strengthen the immune system?
It allows the body to increase its internal temperature.
It allows the body to regulate the inflammatory response.
It allows the body to keep pathogen information for future infections.

Correct answer: "It allows the body to keep pathogen information for future infections."
Why: Vaccines expose the immune system to harmless forms or parts of a pathogen (antigens). That triggers an adaptive immune response that produces antibodies and, importantly, memory B and T cells. Those memory cells “remember” the pathogen so if the real pathogen appears later the immune system responds faster and stronger, often preventing illness.
(The other two choices—raising internal temperature and regulating inflammation—are not the primary mechanisms by which vaccination protects you.)
