Vaccines are effective because they lead to the production of memory cells which remembers the experience when the body got an exposure to the antigen for the first time.
When the antigen get exposed to the body, B cells of the body are activated. They further get divided into two parts, one part forms plasma cells and the other part forms memory cells.
The plasma cells secrete antibodies in the blood to fight disease and other part gets stored in the lymph until it is exposed for the second to antigen which will convert them into plasma cells.
The reserved cells are known as memory cells.
