A vaccine is a preparation that stimulates an immune response which can prevent an infection or create resistance to an infection. The vaccines are injected in the body to prevent the chances of catching diseases that can effect the health of a person. Vaccination is based on the property of the memory of the immune system. when a microbe infects our body during natural infection, our immune system takes time to react to the microbe and destroy it and we get the disease. but when vaccines are given in the form of killed or inactivated microbes, antibodies are produced in our body against that microbe and these remain as memory in our body for ever. On the actual infection by the same microbe (the one taken in the form of vaccine) our body recognizes the pathogen quickly and overwhelm the invaders with strong immune response and prevents our body from getting any disease.
