Detailed explanation-1: -The yellow fever vaccine containing attenuated yellow fever viruses; The Var or varicella zoster virus vaccine containing attenuated varicella zoster viruses.
Detailed explanation-2: -Artificially acquired active immunity is protection produced by intentional exposure of a person to antigens in a vaccine, so as to produce an active and lasting immune response.
Detailed explanation-3: -Artificially-acquired passive immunity is an immediate, but short-term immunization provided by the injection of antibodies, such as gamma globulin, that are not produced by the recipient’s cells. These antibodies are developed in another individual or animal and then injected into another individual.
Detailed explanation-4: -Active Immunity-antibodies that develop in a person’s own immune system after the body is exposed to an antigen through a disease or when you get an immunization (i.e. a flu shot). This type of immunity lasts for a long time.
Detailed explanation-5: -Vaccines contribute to active immunity by providing us with a controlled way to create an immune response. When a vaccine is introduced, our immune system treats it like any other exposure. It works to stop the “assault” and, in the process, immunologic memory develops.
Detailed explanation-6: -Vaccines contain a harmless form of the bacteria or virus that causes the disease you are being immunised against. The bacteria or virus will be killed, greatly weakened, or broken down into small parts before use in the vaccine so that they can trigger an immune response without making you sick.
