Answer: Vaccination often the only feasible way to control many viral diseases because viral diseases cannot be effectively treated once a person become infected with. However, owing to the enormous variations in viruses, their epidemiology and pathogenesis, there is no single, magic- bullet approach to control diseases caused by them. Thus, vaccination is one of the way to control viral diseases. Vaccine is a material the antigen or a mixture of antigens (i.e. non-toxic or non-virulent preparation) used to induce artificial active immunity. The vaccines can be used to induce long term humoral as well as cell mediated immune response against pathogen. And a process of generating such an immune response is immunization or vaccination. The active immunization involves administering a virus preparation that stimulates the body\'s immune system to produce its own specific immunity. Now a days, the viral vaccines are available in the form of: Example: The Sabin polio vaccine (an attenuated vaccine), induces production of secretory IgA, which serve as an important defense against naturally aquired poliovirus.

Vaccination often the only feasible way to control many viral diseases because viral diseases
cannot be effectively treated once a person become infected with. However, owing to the

bullet approach to control diseases caused by them. Thus, vaccination is one of the way to
control viral diseases.
