Antigen: An antigen is a substance which when introduced into the system is capable of including an immune response leading to the formation of antibody with which it reacts specifically.
     
Antibody: An antibody is a modified globulin (immunoglobulin) produced in response to an antigen with which it reacts specifically.
     
Immunization: It is a technique by which immunizing agents are introduced into the body for the production of antibody to prevent diseases.
  
    
Toxin: It is the product of bacterial metabolism and is toxic, i.e., inhibitory or lethal to the cells of the host.
   Toxin may be –
    (i) endotoxin
    (ii) exotoxin
