2.63B understand how vaccination results in the manufacture of memory cells, which enable future antibody production to the pathogen to occur sooner, faster and in greater quantity

Vaccination&Immune Response:
-During vaccinations, you are injected with a harmless dose of bacteria/pathogen, that acts as an antigen.
-This will stimulate immune response so lymphocyte will split to 2 cells.
-1 cell will produce antibodies that will deactivate antigens of bacteria.
-the other cell will be a memory cell that will stay in the immune system.
-If the same pathogen/bacteria is detected , the memory cell allows production of the same antibodies sooner, faster and in greater quantity, stopping the spread of diseases.
