Q. 5

How does vaccination protect a person suffering from a disease?

Answer :

Vaccination cannot protect a person who is already suffering from a disease. Vaccination is an injection given during early stage of life, which has killed or weakened microbes in it in order to stimulate the immune system of the baby so that if the pathogen again attacks the person, the pre formed antibodies can fight and kill the disease causing microbe. So if a person is already suffering from the disease we cannot vaccination will not help.
