A vaccine is an immunizer that usually contains dead, or live, weakened microbes that should not be able to infect a person. When these microbes interact with the immune system, it synthesizes antibodies that have the capacity to kill the microbes.
If the person is infected by the same disease after vaccination, the neutrophils will be able to recognize the microbes, and will alert the immune system to it. Then, other white blood cels and lymphocytes will begin producing anti-bodies and engulfing tge microbes, curing the person.
