Answer:

Since the first vaccine was developed in 1796, vaccinations have been phenomenally successful at preventing infectious diseases, and wiping out some altogether.

After you have been vaccinated, some of the cells that are responsible for protecting you against disease — your B lymphocytes — detect the antigens in the vaccine. The B lymphocytes will react as if the real infectious organism was invading your body. They multiply to form an army of identical cells that are able to respond to the antigens in the vaccine. The cloned cells then evolve into one of 2 types of cells:

plasma cells; or

memory B cells.
