Effectiveness Of Vaccines

The effectiveness of vaccines is based on immunological memory that can be defined as a heightened immune response directed against a previously encountered microorganism and characterised by an increased number of antigen-specific cells and their capacity to respond to a secondary stimulation, through both antibody production and T cell responses. The active immunization that results after vaccination is the consequence of the exposure of the host to an antigen followed by the stimulation of humoral and cell-mediated components of immune response enhancing the ability of the host to react to a second exposure to the same antigen. Vaccines induce a specific immune response in the host through the activation of both innate and acquired immune cells. Antigen vaccines are able to recognize and activate PRRs.
