Vaccines essentially introduce a weakened preview of a viral pathogen to an organism. These pathogens stimulate memory cells that will effectively destroy the natural version of the viral infection when it comes in contact with the organism. In this case, the prepared memory cells generate large amounts of antibodies and lymphocytes to kill the virus.
