Vaccines are like a training course for the immune system. They prepare the body to fight disease without exposing it to disease symptoms.
When foreign invaders such as bacteria or viruses enter the body, immune cells called lymphocytes respond by producing antibodies, which are protein molecules. These antibodies fight the invader known as an antigen and protect against further infection. According to the Centers for Disease Control and Prevention (CDC), a healthy individual can produce millions of antibodies a day, fighting infection so efficiently that people never even know they were exposed to an antigen.

HEYA!!!
HERE IS YOUR ANSWER,
> 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 the microbes, curing the person.
HOPE IT HELPS YOU,
THANK YOU.☺️☺️
