Answer 1

The amount of circulating antibodies against a particular antigen rises after vaccination. B cells are a particular type of white blood cell (lymphocyte) that make antibodies. One unique epitope is the only one against which a B cell may make antibodies.

A type of white blood cell called a lymphocyte is a component of the immune system. B cells and T cells are the two primary subtypes of lymphocytes. Antibodies made by B cells are utilised to combat foreign bacteria, viruses, and poisons. The body's own cells that have contracted viruses or developed malignancy are destroyed by the T cells. The immune system is made up of lymphocytes, which are blood-circulating immune system cells. The two primary categories of lymphocytes are T cells and B cells.
