How does a vaccine work?

To understand how Vaccine works, we should know how the immune system of our body works. When a foreign body enters into a human body, the immune system gets activated. The white blood cells produce antibodies in response to the foreign object and neutralize the object. But this doesn’t happen instantly it takes several days. During this period the foreign object if it is a living virus or bacteria it reproduces and causes various diseases. After a certain time, White
blood cells will be able to contain this situation. This is stored in the form of memory in the body. And when the same object enters into the body, the body is prepared for that.

Similar happens with the vaccine. When the vaccine is given to a person, white blood cells get activated thinking of it is a foreign object. It contains the object and stores the information for future use.
