Vaccines are used to boost the immune system and prevent serious life-threatening diseases. Vaccines expose you to a very small, very safe amount of viruses or bacteria that have been weakened or killed. Your immune system then learns to recognize and attack the infection if you are exposed to it later in life. As a result, you will not become ill, or you may have a milder infection. This is a natural way to deal with infectious diseases.
