    1-though vaccination if you are talking about active inmunity

    or 2- passive inmunity which diminishes in a relatively short time, usually a few weeks or months

    Definition of Active immunity

    Active immunity: The production of antibodies against a specific agent by the immune system. Active immunity can be acquired in two ways:

    * by contracting an infectious disease -- such as, for example, chickenpox; or

    * by receiving a vaccination usually pe-- such as, for example, against polio.

    Active immunity is permanent. The individual is protected from the disease all their life.

    There is no way to have active immunity to a disease without getting it, or small strain of it (which is vaccination). I think that the best response is B.

    If your asking which one of thise. i would say B just because a vaccination is the disease your trying to prevent against, your getting avery small dose of it...either that or they are dead. Your body will build up an amunity to it and be able to defend your body against it when exposed.
