A)Administration of the vaccine introduces a small number of weakened yellow fever viruses into the body. Macrophages ingest these viruses while also presenting the viruses' antigens to T cells and B cells. Exposure to the antigens causes the T cells to attack the yellow fever viruses. It also triggers the B cells to begin secreting yellow fever antibodies, which attack and destroy yellow fever antigens. Thus, the initial weak infection is eliminated and the body is left with a supply of memory T and B cells that provide future protection against the yellow fever virus. In this way, vaccination leads to the development of active immunity, unlike administration of large amounts of antibodies that were produced in another host, which is a type of passive immunity.
