Correct option is C)

  • A vaccine is a biological preparation that provides acquired immunity to a particular disease. 
  • Vaccines are made from microbes. The antigen in the vaccine is the same as the antigen on the surface of the disease-causing microbe. 
  • The vaccine stimulates the body to produce antibodies against the antigen in the vaccine. 
  • The antibodies created will be the same as those produced if the person was exposed to the pathogen. 
  • When the vaccinated person comes into contact with the disease-causing microbe, the antibodies recognize the pathogen and act against it. Hence, the vaccine should be given before attacking the disease. 
So, the correct answer is option C.
