    Yes by vaccination it is called active artificial immunity and developing an infection is called active natural immunity. Getting sick naturally is better because you immune response is stronger and creates better memory.

    Immunity derived from immunization/vaccines:

    - Artificially Acquired Active Immunity

    Immunity developed from infection:

    - Naturally Acquired Active Immunity

    When you get an immunization, you receive the virus itself, however it's in a dormant state so no harm is done. The body reacts to the virus and builds up a defense so when the time that the real virus develops, there is already a defense for that particular virus.

    When you develop an infection, there was no prior defense and the body is reacting to the present state infection and not to one that was built before hand.

    It depends on the immunization. The killed Salk polio vaccine that is injected provides you with protection from paralysis after you are already infected, but does not protect from being infected.

    The Sabin live polio virus vaccine that was given orally, actually sets up an infection that protects against both infection and paralysis, just like the natural infection would, if you survived.
