प्रश्न
Answer the following question in your own words.
Explain the meaning of vaccination.
उत्तर
Vaccines are the dead or weakened microorganisms, which help the body in fighting against diseases. Our body reacts to infection by microorganisms by producing certain substances called antibodies. These antibodies kill the invading microorganisms, thereby freeing the body from diseases. In order to protect the body from diseases caused by microorganisms, some dead or weakened microbes are introduced in the body, which cause the production of antibodies. These antibodies then remain in the body for a long period of time protecting the body from diseases. This whole process of introducing vaccines into the body is known as vaccination.
