Vaccines are like a training course for the immune system. They prepare the body to fight disease without exposing it to disease symptoms. When foreign invaders such as bacteria or viruses enter the body, immune cells called lymphocytes respond by producing antibodies, which are protein molecules

Answer:
When a disease carrying microbes enter in our body the body produces antibodies to fight the invader. The body also remembers how to fight and kills the microbes by producing suitable antibiotics. The antibodies remain in the body and we are protected from disease causing microbes. Thus a vaccine works.
