The administration of the hepatitis A vaccine leads to immune activation of lymphocytes, which proceed to engulf the hepatitis A antigen, leading to the release of inflammatory mediators that stimulate B and T cells to attack the viral antigen. Following this stimulation, the B cells and T cells then differentiate into memory cells, antibody-producing B cells, cytotoxic T cells, and helper T cells to provide immunity against infection with Hepatitis A.
