${\huge{\underline{\underline{\sf{\blue{Answer:-}}}}}}$

A substance used to produce immunity against diseases in the living body is called a vaccine. Vaccines are prepared by using the dead or weekend disease causing microbes. Immunity is the ability of the body to fight against diseases. Immunity can be natural or artificial ( in form of vaccines ). The process of producing immunity by injecting into the body is called vaccination.

When diseases carrying microbe enters our body, the body produces a substance called antibodies. The antibodies fight and destroy the invader ( disease carrying microbe ). The body also remembers how to find the microbe if it enters again in future as the antibodies remain in the body. Thus, the body produce immunity against the disease. This is how a vaccine works. Several diseases, including cholera, tuberculosis, smallpox and hepatitis can be prevented by vaccination.
