Yes, vaccines contain a weakened form of the disease that is injected into the bloodstream, your immune system detects this weakened disease as a threat and neutralizes it, but also copies the coding of the disease so you can quickly get rid of it if or when it attacks.
Vaccines are not effective against a virus for very long though, due to a virus changing its structure , but for most bacteria diseases it is.
