Vaccination involves:

Correct option is A

Ans. (a) Sol. Vaccination involves injecting the body with materials that stimulate the body to produce antibodies. These materials are usually weakened or inactivated forms of pathogens (like viruses or bacteria) or parts of the pathogen (like proteins), which stimulate the immune system to recognize and fight off the pathogen if it encounters it in the future.
· Option (b): Vaccination does not stimulate the body to produce antigens. Rather, it stimulates the production of antibodies that can recognize and neutralize antigens.
· Option (c): The use of monoclonal antibodies is a form of passive immunity, not vaccination. Monoclonal antibodies are used to treat diseases but are not used for vaccination.
· Option (d): Antibiotics are used to treat bacterial infections, not for vaccination, which is a preventive measure.
